INTRODUCTION

1.1

The VX-4c/VX-6c projector is a professional quality

DMD projector that uses Digital Light Processing

(DLP ) technology from Texas Instruments to achieve

high-brightness multimedia and video projection. The

VX-4c/VX-6c is compatible with standard international

video formats and can interface with IBM -compatible

PC, Macintosh computers and high-definition (DTV)

decoders. The VX-4c/VX-6c is ideal for use in both large

and small home theaters; performing exceptionally well

in venues with ambient light.

The features of the VX-4c/VX-6c include:

ꢀThe VHD Ultra Controller for optimum picture quality when using NTSC sources

ꢀ1280 x 1024 native resolution, with other resolutions fully scaleable

ꢀ3000 ANSI lumens light output (6000 ANSI VX-6c)

ꢀConstant height aspect ratio control up to 2.35:1 screens

ꢀInterchangeable lenses for screen widths up to 500 inches

ꢀMemory for up to 99 custom “Memory Banks” (source setups)

ꢀIntuitive on-screen menus or hidden direct control

ꢀModular design for easy servicing.

How The Projector Works?

The VX-4c/VX-6c can accept data/graphics and video input signals for projection on to front or

rear flat screens. High brightness is generated by an internal 700W (1200W VX-6c) Xenon arc

lamp, then modulated by three DMD (digital micromirror device) panels that provide digitized

red, green or blue color information. Light from the “on” pixels of each panel is reflected, con-

verged and then projected to the screen through a single front lens, where all pixels are perfectly

superimposed as a sharp full-color image.

ANAMORPHIC LENS

DLP™ projectors use a small device called a DMD™ (Digital Micromirror Device) to create the

video image. DMDs are designed in aspect ratios ranging from 4:3 (standard) and 16:9

(widescreen), to 5:4 (digital cinema). Understanding that more and more home theaters are

designed using 16:9 or cinemascope projection screens (similar to your local Cineplex's), Runco

has developed an anamorphic lens system to make the 5:4 DMD fully compatible with a home

theater that has 16:9 and 2.35 screen formats.

The Runco Anamorphic Optical System elevates the image quality of a 16:9 picture to a higher

level. This system consists of two components; one being the controller and the other the anamor-

phic lens. The first component is Runco's award-winning Vivix™ VHD™ Ultra Controller with

10-bit processing which is used to scale the video signal to mach the native resolution of the pro-

jector. The second part utilizes one of three anamorphic lenses that optically stretch the image to

a 16:9 or 2.35 aspect ratio.

The advantages of using the anamorphic lens system is that it takes advantage of the entire mir-

ror array on the DMD™ resulting in a higher resolution picture. The result is a high-resolution

picture in a big screen format for the home theater. Another benefit of employing all the mirrors

on a DMD™ is 25% greater light output for an increase in picture brightness. Runco's industry-

renowned controller helps to trigger the electronic corrections for the stretched image and pro-

vides four geometrically correct aspect ratios - 16:9 widescreen, letterbox, 4:3 and VirtualWide™.

HDTV is also geometrically correct and has higher resolution. The Anamorphic optical systems

include an Anamorphic lens, the lens mount assembly, and an Anamorphic Vivix™ Controller.

The Anamorphic Optical System is the ultimate way to maximize resolution and will significant-

ly shorten the throw distance of any Video XTreme™ series projector it is used with. Consult the

specification sheet of the projector for specific throw distance calculations.

carefully and retain it with your other important documents.

LIMITED WARRANTY as defined in the Magnuson-Moss Warranty Act. Please read it

WHAT IS COVERED UNDER THE TERMS OF THIS LIMITED WARRANTY:

SERVICE LABOR: Runco will pay for service labor by

needed as result of manufacturing defect for period of two (2) years from the effective date of

delivery to the end user (excluding the lamp).

Runco Authorized Service Center when

PARTS: (Not including the lamp) Runco will provide new or rebuilt replacement parts for the parts

that fail due to defects in materials or workmanship for period of two (2) years from the effective

date of delivery to the end user. Such replacement parts are then subsequently warranted for the

remaining portion (if any) of the original warranty period.

PROJECTOR LAMP: Runco will pay for service labor by Runco Authorized Service Center when

needed as result of manufacturing defect for period of six (6) months or 1000 hours, which ever

comes first, from the effective date of delivery to the end user. In addition, Runco will provide new

or rebuilt replacement lamp for the lamp that fails due to defects in materials or workmanship for

period of six (6) months or 1000 hours, which ever comes first, from the effective date of delivery to

the end user. Such replacement lamps are then subsequently warranted for the remaining portion (if

any) of the original warranty period.

WHAT IS NOT COVERED UNDER THE TERMS OF THIS LIMITED WARRANTY:

Image burn-in on CRT projectors are specifically excluded from coverage under this Limited Warranty

Image burn-in is the result of misuse of the product and therefore cannot be repaired under the terms

of this Limited Warranty

TO AVOID IMAGE BURN-IN:

Please ensure that still images are left on your CRT projector for no more than

few minutes. Also

ensure that images displayed in the 4:3 aspect ratio mode (black or gray stripes, but no picture

information is present on the left and right edges of the screen) are used as infrequently as possible.

This will prevent permanent image burns on your CRT projector, which can be seen permanently

under certain conditions once burn-in has occurred.

The types of images to avoid include video games, still images and computer screens with stationary

to prevent still images

tool bars and icons. (This is why computers are equipped with screen savers

–

from burning into the monitor’s phosphors after being displayed continuously for an extended period

of time).

Normal viewing material such as television/satellite broadcasts, videotape or DVDs (not put into

pause for extended periods of time) will not cause damage to your display under normal conditions.

Many DVD players are also equipped with screen savers for this reason.

Installing The Lens

A variety of lenses are available to accommodate different throw distances and specific types of

installations. See page 2-10 for details. To change/install a lens, follow the steps below.

NOTES: 1) You will need a 9/64”(3mm or 3.5mm) hex socket ball driver (supplied with projec-

tor) or allen wrench for this procedure. 2) “Top” or “bottom” references assume a non-inverted

projector, as illustrated. 3) If you are installing a lens, first make sure its Lens Adapter is present

on either the lens or projector. Such an adapter/flange secures to the projector in the same man-

ner as the flange described below, but accommodates a screw-mount lens.

STEP 1ꢀTurn off the projector, cool, and unplug.

Before removing or installing a lens, turn off the

projector and allow it to cool for five minutes before

unplugging. Make sure that the lens cap is on.

WARNING

Install Lens Cap

Unplug the projector.

Install the lens cap.

STEP 2ꢀLoosen the 3 lens mount screws

ꢀIF FIXED LENS: Use the hex socket ball driver

provided with the projector to loosen the 3 lens mount

screws that secure the lens flange to the mount-loosen

these screws only, do not remove.

INSTALLATION AND SETUP

STEP 4ꢀ Pull lens assembly out

ꢀCarefully pull the lens assembly straight out of the projector

and set aside.

Remove Lens Assembly

STEP 5ꢀInstall new lens assembly

ꢀIMPORTANT: Remove the rear (smallest) lens cap from the new

lens. Make sure the front lens cap remains on during installation.

ꢀAlign the large cut-out area on the lens flange to the bottom of the

lens mount (which has a matching cut-out). The 3 lens assembly slots

should align with the lens mount screws so that the screw heads will fit

through the large end of the slots (see Orientation figure).

NOTE: On most lenses, a small extra “keying” slot located at approxi-

mately 2 o’clock on the lens flange will align with a set screw in the same

location on the lens mount, preventing the lens from being installed in the

wrong orientation. If the lens flange does not seem to fit into place over all

screws, try rotating the lens assembly in one direction or another.

to refine other display parameters, if necessary. See 3.5 Using Inputs and Memory Banks if you want

to work with other source inputs or defined memory banks.

You may want to reduce initial setup time by starting with an “Auto Setup”. The projector will automatically

optimize a variety of display settings according to the incoming source detected. You can then re-adjust these

settings at any time, if desired.

2.3

Installation Considerations

Although this projector delivers a high brightness quality output, final display quality could be

compromised if the projector is not properly installed. This subsection discusses issues you

should consider before proceeding with a final installation. Even if you do not intend to use the

projectors in a fixed and permanent installation, this subsection will help you to better understand

what you can do to enhance display performance.

Lifting

For any new installation, you will likely have to safely lift the projector into place. Keep in mind

that the projector is quite heavy, and the aid of a CO²or other type of mechanical lift is highly

recommended.

2.4

Additional Considerations

Here are some other considerations and tips which can help you improve your installation:

Ventilation is an important factor when preparing a projection room. The ambient

temperature should be kept constant and below 35°C (95°F). Keep the projector

away from heating and/or air conditioning vents. Changes in temperature can

cause drifts in the projector circuitry that may affect performance.

ꢀKeep the projector away from devices that radiate electromagnetic energy such as motors and

transformers. Common sources of these are slide projectors, speakers, power amplifiers, ele-

vators, etc.

ꢀFor rear screen applications, less space is required if a mirror is used to fold the optical path.

ꢀChoose the right screen size for the application:

U As screen size increases, magnification increases and reduces brightness. Select a screen

size which is appropriate for the theater, but not larger than what is required.

U Installing a large screen in a small room is similar to watching television close up; too

large a screen can overpower a room. A good rule of thumb is to be no closer than 1.5

times the width of the screen.

U Larger screens require greater attention to lighting conditions.

INSTALLATION AND SETUP

Always consult this section when planning a projector installation. See also section 2.7 and 2.8, Projector

Position and Mounting.

Calculating Throw Distance

Correct throw distance depends on the screen size and lens present-the larger the image needed,

the greater the distance you must allow between the lens and screen. Once you know the screen

size and lens type present, you can calculate the precise throw distance you require by using the

appropriate formula as found in this appendix.

Throw distance is the distance between the projector front feet and the screen. This measurement

is not necessarily parallel to the floor-i.e., the projector and screen may be inclined.

NOTE: If your projector is tilted

up or down in relation to the

screen, as is sometimes the case

for large venues or elevated

installations, throw distance still

represents the smallest measure-

ment between the screen and

front feet centers.

Pre-calculated throw distances for the complete range of lens types and screen sizes appear in the

charts and graphs on the following pages. Refer to these examples to quickly determine the prop-

er throw distance (±5%) for your installation and lens.

NOTE: Variable operating ranges for zoom lenses appear in graphs only.

INSTALLATION AND SETUP

2.6

Vertical & Horizontal Position

THE VERTICAL POSITION of the projector in relation to the screen also depends on the size

of the screen and the lens type. Correct vertical position helps ensure that the image will be rec-

tangular in shape rather than keystoned (having non-parallel sides) and that image focus and

brightness both remain optimized.

In addition, vertical position of the image can be manually offset-that is, moved up or down-by

turning the top screw on the front of the projector (the bottom screw if the projector is ceiling

mounted). The range of adjustment is roughly 130%, depending on the specific lens you are using

and whether or not you are also offsetting horizontally. See Table 1 for the percentage of the

image that can be displayed above and below the center of each type of lens designed for this pro-

jector. These image offsets are also illustrated below (Fixed Lenses) and on the following page

(Zoom Lenses).

Maximum Vertical Offsets (ZOOM LENSES)

NOTES: 1) If you cannot raise or lower the image enough using

mechanical vertical offsets, try adjusting V-Shift in the Scaling

Parameters menu (see 3.6, Adjusting the Image). 2) If the image

becomes keystoned or exhibits uneven brightness, the projector

may simply be too high or low in relation to the screen.

3) Recommended offset ranges can be exceeded, however this may

affect image quality. 4) Simultaneous horizontal and vertical

offset limits the adjustment range of each.

THE HORIZONTAL POSITION of the image can be offset-that is, shifted left or right of lens center-by

turning the bottom screw on the front of the projector (the top screw if the projector is ceiling mounted). The

maximum horizontal offsets for the lenses designed for this projector is shown on the following page. For this

projector, this value expresses the maximum percentage of the image that can be projected to one side of the lens

center (roughly 80%, depending on the lens).

Mounting

For typical front or rear floor mounts, mount the projector on a secure table

or cart. Take care with a mobile cart-avoid sudden stops, excessive force and

uneven surfaces that may cause the projector and cart combination to over-

turn.

The table or cart should be reasonably level. Fine adjustments to the projec-

tor level can be made by adjusting the height of the projector legs.

Special Mounting

Note that projector can be rotated and mounted at any vertical angle-i.e., you can tilt the face of

the projector up or down as much as desired for your installation. The side-to-side tilt, however,

must not exceed 15° (see below). This limit ensures that the arc lamp in the projector operates

properly and safely. Always make sure that exhaust air from the projector does not vent towards

the lens, otherwise you may detect heat waves in your projected image.

Horizontal and Vertical Tilt Ranges

You must use the proper ceiling mount fixture or stacking kit for your projector. For more infor-

mation, contact your Runco Dealer.

Folded Optics

In rear screen applications where space behind the pro-

jector is limited, a mirror may be used to fold the opti-

cal path. The position of the projector and mirror must

be accurately set-if considering this type of installation,

call your Runco dealer for assistance.

2.9

Source Connections

The rear panel of the projector provides standard input panels to which you may connect a vari-

ety of sources. See below - the lower left area (INPUT 1) typically accepts an RGB signal from

an external RGB source (such as the VHD Ultra Controller), or it can also be used for YPbPr sig-

nals from DTV sources. The upper right panel-the Video Decoder Module-accepts only compos-

ite video at INPUT 3 or S-video at INPUT 4 from devices such as VCRs, laser disc players or

DVD players. There are also several optional interfaces available for connecting other sources at

INPUT 2. Such an option installs in the upper left area, just below the audio connectors. For any

input, including the optional inputs, audio with loop through connects at the audio input panel

located between the license label area and INPUT 2.

Note: The decoder module is an option; it is not supplied with the Projector.

INSTALLATION AND SETUP

2.10 RGB Signals

INPUT 1 provides 5 BNCs (connectors) for linking to a variety of sources. The typical connec-

tion would be to an RGB source such as the VHD Ultra Controller, computers or DTV decoders

with an RGB output. This projector supports multiple sync types with RGB signals: sync-on-

green, composite sync, and separate H & V syncs.

NOTES: Depending on the source, you may need a custom adapter cable that has BNC connec-

tors at the projector end and a different type of connector at the other (such as a 15-pin “D” con-

nector for computer sources). Contact your Runco dealer.

Connect the SYNC BNC input(s) first. Then connect the red, green and blue source outputs to the

RED, GREEN, and BLUE BNCs on the INPUT 1 panel. If the source uses sync-on-green, only

the red, green, and blue connections are required. If the source provides a composite sync output,

connect it to the SYNC input labeled HOR/COMP. If the source provides separate horizontal

and vertical sync outputs, connect horizontal sync to the SYNC input labeled HOR/COMP and

connect vertical sync to SYNC input labeled VERT. See below.

NOTE: To connect YPbPr signals, such as from analog HDTV sources, to INPUT 1, use the red,

green and blue BNCs as described in YPbPr Signals later in this section.

Connecting RGB Input

AUDIO for INPUT 1: To control audio levels in an audio/visual system, connect pre-amplified (line level) audio

inputs to the “IN 1” left and right channel audio inputs located near the top left corner of the rear input panel.

Then connect external audio amplification equipment to audio “OUT” for sound output. Audio connection

cables require standard RCA type phono plugs.

INSTALLATION AND SETUP

2.11 Keypad Protocols and Conversion

The keypad is assigned “A” as its default protocol, which is simply a collection of settings that

determine how the keypad operates. Once assigned, this protocol remains in effect until it is

changed-that is, the keypad will operate as it currently does until you change its protocol.

Protocols are most useful for multiple-projector applications. For example, you might want to

change a keypad protocol if you are working with two projectors and two remote keypads in the

same room and need to control each projector independently (see below). When Keypad A has a

different protocol than Keypad B, each keypad communicates only with the projector having a

matching protocol. Or, if you have a network of two or more projectors connected together via

RS-232 serial ports, you may want only certain projectors to respond to a wired keypad, thus you

can use different protocols to limit responses.

NOTE: Matching the protocol on the projector to that of a keypad is done through a setting in the

Serial Setup menu. See 3.7, Adjusting System Parameters and Advanced Controls for further

information on how to change the projector’s infrared sensor (rear and front) protocol.

A protocol for either type of remote keypad - IR or wired - can be changed through software com-

mands entered on the keypad. A new protocol set through software commands remains in effect

until the keypad batteries are removed and replaced (if an IR remote), or until the keypad is

unplugged (if a wired remote). A remote can also be changed manually -you can “hard-wire” new

jumper settings inside the keypad so that they remain in effect until you change the hard-wiring.

A hard-wired protocol can be temporarily overridden by the software protocol change, effective

until the keypad is unplugged and plugged in again (if a wired remote) or until a battery is

removed (if an IR remote).

AC LINE CORD INPUT - The projector requires AC power of 100 to 240 VAC, 50 to 60 Hz

(11.5 amps @ 100 VAC, 5.5 amps @ 220 VAC). Always use the line cord that is supplied with

the projector-the projector requires this high-current 13A rated cord. See complete power speci-

fications in Section 5.

WARNING

Do not attempt operation if the AC supply is not

within the specified voltage and power range.

STATUS/POWER LEDS - Two LEDs (light emitting diodes) located in the lower right corner of

the rear connector panel indicate projector “Status” (top) and “Power” (bottom). During normal

operation, the “Power” light is steady green and the “Status” light flashes green each time a key

is pressed or when the projector receives a serial command. Use the following as a guide:

Using the Keypad The keypad appears in two locations:

ꢀ

Infrared (IR) Remote for wireless control up to 100 feet away

Wired Remote (optional) tethered to the rear of the projector

While each keypad is identical in layout and provides complete control of the projector, you may

find one keypad more convenient than another for your specific installation and application.

IR Remote

The IR Remote Keypad controls the projector by way of wireless communications from a battery-

powered infrared (IR) transmitter. Use the IR remote keypad the same way you would use a

remote keypad supplied with a TV or VCR. When making key presses, point the keypad either

toward the screen or toward the front or rear of the projector. One of two sensors on the projec-

tor will detect the signals and relay the commands for internal processing.

Wired Remote (OPTIONAL)

The wired remote keypad connects to the 3-pin XLR jack via a 50 ft. cable. It is recommended

when:

Using Inputs and Memory Banks

NOTE: See Section 2, Installation and Setup, for a full explanation of how to connect a variety

of sources to the projector.

The projector stores and automatically recalls up to 99 different Memory Banks (source setups)

for a variety of inputs. This memory feature allows you to define and conveniently use a wide

variety of customized setups rather than having to repeatedly re-configure the projector for dif-

ferent presentations. Each physical source (i.e., input) can have several different Memory Banks

associated with it.

Selecting an Input ꢀ

INPUT - An input simply describes a physical location for an incoming signal connection.

These connections are always either on the projector itself (one of the four inputs at the rear of

the projector).

EXAMPLE:

Input

Input1

= use source connected to the projector, slot #1 (i.e.,

)

Input1

Pressing the appropriate direct key -

, or

- is a quick and seamless way to

display from one of the four inputs connected at the rear of the projector.

If it is the first time you have used the source/input (or if you used the input but did not define

a Memory Bank by adjusting anything ), the projector will recognize the new input signal based

on its frequencies and polarities, and will automatically display an image according to default set-

tings for such a signal. Note that a graphic source will resize into a full-screen image, whereas

video or HDTV sources will resize only as much as possible while maintaining their aspect ratio.

If you used the source once before and changed a display parameter such as contrast, V-Shift

etc., then a Memory Bank was automatically created and still exists in projector memory (see

Input

below). Using an

key will automatically recall this Memory Bank - and all its setup param-

eters - and update the display accordingly.

If more than one Memory Bank exists for the input, the image will be displayed according to

the setup parameters for the first Memory Bank with matching characteristics.

OPERATION

MEMORY BANK - A Memory Bank is a collection of measurements, locations and settings that

tailor a display to your specific needs. Since source types and applications can vary greatly, you

will likely want to adjust and define a wide variety of parameters, such as brightness, contrast,

tint, size, etc., in order to customize and optimize the display coming from a particular source.

For example, the display settings you choose for a VCR source may be very different from those

you choose for a high resolution computer source, or one signal may simply vary from another

signal used earlier through the same input location. Once you have adjusted a display parameter,

such as pixel tracking or contrast, all current settings are collectively stored in the projector's

memory as a unique 2-digit Memory Bank, such as

. You can have numerous distinct

Memory Banks available for the same input, any of which can be selected by using the key on the

keypad followed by the 2-digit Memory Bank number.

key may display a Memory Bank list or not, depending on what you have

In order to use Memory Banks (

on the keypad), you must first create them. See below.

Creating a New Memory Bank ꢀ - AUTOMATIC -

To use a new source with the projector, a new Memory Bank must be added to projector memo-

ry so that the projector will respond properly to an input signal from that source in the future. A

new Memory Bank can be created automatically, as described here, or it can be copied from an

existing Memory Bank and then edited as necessary (see Copying or Deleting Memory Banks

later in this section).

Input

Input1

When you select a direct input (press

, or

), the existing Memory

Banks in the projector are searched for matching input and signal parameters. If no match to the

incoming input signal is found in the currently defined Memory Banks, a new Memory Bank is

temporarily created based on factory-defined defaults for this signal. The Memory Bank Number

assigned to this Memory Bank is the lowest available number from 01-99.

NOTES: 1) An automatic Memory Bank will be discarded unless one or more of its parameters

are changed, and will not appear in the Bank List (see below). 2) If two Memory Banks have

the same distinguishing source characteristics except for the reversal of sync connectors (i.e.,

H-sync and V-sync, are switched), they are still defined as distinct Memory Banks. 3) You can-

not define a new Memory Bank without a signal present.

If the incoming signal does match an existing Memory Bank, the image will be set up and dis-

played as usual according to the parameters currently defined for that Memory Bank.

Total H Dots:

Pixel

(SHORT CUT: Press

and adjust the top slidebar.)

Total H Dots adjusts the frequency of the pixel sampling clock, indicated by the number of pix-

els per line, so that all pixels generated by a particular source are sampled. Proper pixel tracking

ensures that the image quality-whether good or poor- is consistent across the screen, and that V

Dots can be optimized (below).

NOTE: By default, the projector will sample at the correct frequency for most sources.

Total H Dots is adjusted most effectively using a good test pattern, such as a smooth gray con-

sisting of a clear pattern of tiny black and white dots, or a similar “half on, half off” graphic

image, such as the Windows shutdown screen. Steady flickering or several soft vertical stripes or

bands across the entire image indicates poor horizontal dots. Adjust the slidebar until the stripes

broaden to the point where one large stripe fills the image. Again, the image may still exhibit

some noise. See Fine V Dots.

Fine V Dots

Pixel

(SHORT CUT: Press

and adjust the bottom slidebar.)

Fine V Dots adjusts the phase of the vertical dots sampling clock relative to the incoming sig-

nal. It is used primarily for adjusting RGB inputs.

NOTE: Adjust Fine V dots after Totat H dots is properly set.

Adjust Fine V Dots when the image (usually from an RGB source) shows shimmer or “noise”.

Fine V Dots adjustment is done most effectively from within a proper test pattern, such as a

smooth gray consisting of a clear pattern of tiny black and white dots, or a similar graphic image.

Adjust until the image is stable and each dot is clearly defined. Using the numbers on the slide-

bar as a guide, you will notice that you can actually stabilize the image at more than one point-

i.e., you may find that the image appearance at “11” is identical to the image appearance at “38”,

thus you can select either setting.

OPERATION

Contrast

(SHORT CUT: Press

Enter

and adjust the slidebar.)

"Contrast" increases or decreases the perceived difference between light and dark areas of your

image (0-100). If contrast is set too high, the light parts of the image lose detail and clarity. If set

too low, the light areas will not be as bright as they could be and it may be difficult to distinguish

between foreground and background information. Adjust so that whites remain bright but not dis-

torted or tinted. For best results, keep close to 50.

NOTE: If environment lighting changes, it may be necessary to re-adjust both options.

Brightness

(SHORT CUT: Press

Bright

and adjust the slidebar.)

"Brightness" increases or decreases the amount of perceived light in the dark part of the image

(0-100). If video or data is displayed with a black background, adjust until the background just

changes from black to very dark gray. For best results, keep close to 50.

Sharpness

(SHORT CUT: Press

Detail

and adjust the slidebar.)

“Detail” adjusts the sharpness of the video image. Use

until the display is as sharp

as possible, keeping in mind that any level of detail above 3 (default) will increase the level of

detail as well as introduce some level of noise in the image. Set below 3 to filter the signal and

remove noise from a noisy source. Keep at 3 to apply no detail. NOTE: DETAIL is not available

in the RGB mode.

OPERATION

Color Balance

Select this submenu to work with aspects of color - adjust for saturation and overall hue in video

signals, or adjust gamma or temperature in any signal.

Color

(SHORT CUT: Press

Color

and adjust the slidebar.)

“Color” adjusts color saturation level, or the amount of color in a video image. For

example, setting Color to “0” produces a black and white image. If Color is set too high,

the color levels in the picture will be over-powering and unrealistic. Use

until the desired color saturation level is displayed. NOTE: COLOR is not available in

the RGB mode.

Tint

(SHORT CUT: Press

and adjust the slidebar.)

“Tint” adjusts color hue to obtain true color reproduction of NTSC video signals. Use

or until you reach optimum balance of red-to-green in your image. It is

best to adjust tint while displaying a proper SMPTE color bar test pattern-otherwise, it is

recommended that tint remain at its default setting. NOTE: TINT is not available in the

RGB mode.

THE ENHANCED SETTING elevates middle gray levels compared to

“Default”, and provides a more gradual rolled-off transition to maximum white.

Together, these differences can improve the apprearance of many kinds of

images.

THE 1.8 SETTING elevates low gray levels compared to the “Default” and “3.2” settings. In

high amibient light conditions, details can be seen in the dark parts of the image that would oth-

erwise be difficult to perceive.

THE 2.5 SETTING results in a darker image with higher contrast. The gamma curve more

closely matches the official standard for PAL and SECAM video signals.

THE 1.0 SETTING is a straight, linear transition from black to white. For normal source sig-

nals, it results in a picture of low contrast with highly elevated low-and mid-level grays. It should

be used only with sources that have their own pre-applied gamma control.

Setting the correct speed is important when you are controlling the

projector with an external device or another projector via an RS-232 or

RS-422 port. You must set the projector baud rate at these ports to

match the baud rate of the controlling device. If you are unsure about

what baud rate to choose, refer to the documentation for the control-

ling device.

OPERATION

Front IR Receiver / Back IR Receiver

As described in Section 2, the standard IR remote keypad is capable of sending

data to the projector in either one of two protocols called A or B. Likewise, the

front and rear IR sensors on the projector can be set to accept IR data accord-

ingly, responding to A, B or both. The projector’s A or B default is adequate

for most single-projector installations. Select a specific protocol to prevent

interference when you are controlling two protectors in the same area and want

to work with one projector at a time.

A or B

Off

Note that the front and rear IR sensors cannot respond to different protocols-if you change a pro-

tocol for either sensor to anything other than OFF, the protocol for the other sensor also changes.

For example, setting Front IR Receiver to B also changes the Back IR Receiver to B. If you want

only one sensor to respond to a particular protocol- A, B, or A or B-disable the other sensor by

setting its protocol to OFF.

If you want to disable both IR sensors, you cannot use the IR remote keypad to select the second

OFF setting. This safeguard prevents accidentally disabling a keypad while you are using it.

Instead, use either the built-in keypad or the wired remote to set the remaining active sensor to

OFF. The projector will no longer respond to an IR remote keypad.

IMPORTANT

Keep at “A OR B” unless you are sure of

the current IR keypad protocol.

NOTES: 1) The IR remote keypad for this projector is set at Runco to “Protocol A”. See 2.12 in

Chapter 2, Keypad Protocols and Conversion for information about changing the keypad proto-

col. 2) A key press from a conflicting protocol will cause a single yellow flash on the Status LED

located in the lower right corner of the rear projector panel.

Wired Keypad

Like the IR remote keypad, the optional wired keypad is either a “Protocol A” keypad (default)

or a “Protocol B” keypad. Likewise, the projector can be set to accept wired keypad data accord-

ingly, responding to A or B. If desired, you can prohibit the projector from responding to a par-

ticular wired keypad protocol, or you can ensure that the projector responds to either protocol

(default). You can also prevent the projector from responding to the keypad entirely. In the pull-

down list, select the desired protocol.

NOTE: The wired keypad for this projector is set at manufacture to “Protocol A”. See 2.12,

Keypad Protocols and Conversion for information about changing the keypad protocol.

Adding a Protocol: To add a protocol, select the A or B option.

3-26

Download from Www.Somanuals.com. All Manuals Search And Download.

OPERATION

Changing a Protocol: As a safeguard, you cannot accidentally select an option in the “Wired

Keypad” list that would disable the wired keypad during use, since such options are automatical-

ly disabled in the list. In other words, you cannot switch to the opposite protocol or select OFF

using the wired keypad. Instead, if you want to quickly change to the other protocol, you may find

it more convenient to use one of the other keypads (the built-in keypad or the IR remote) to exe-

cute the protocol change for the wired keypad. The projector will now recognize only the oppos-

ing change for the wired keypad protocol. Or, if you prefer, use the wired keypad to safely change

its own protocol:

1. Select the A or B option. This will ensure that once your keypad is manually changed

(see Step 2), it will still be recognized by the projector.

2. Unplug the keypad and change the protocol in the keypad as desired. Do this either by

entering the short-cut software command or by hard-wiring the keypad as described in

2.12, Keypad Protocols and Conversion.

3. Plug the keypad back into the projector. Return to the IR and Serial Setup menu and

select the new protocol you have just set up in the wired keypad.

Turning off the wired keypad: If you want to disable the wired keypad entirely, you cannot use

it to select the OFF option. This safeguard prevents you from accidentally disabling the wired

keypad during use. Instead, use either the built-in keypad or the IR remote keypad to select OFF.

The projector will no longer respond to the wired keypad.

1. Use an external grayscale test pattern of some kind (make sure it has both dark grays

Func

and light grays).

2. Make sure the image is displayed in its native resolution, i.e. with No Resizing.

3. Display a single color - choose through the “DMD Enable” menu option or use the key

shortcuts shown on the back of the remote keypad.

4. Examine an area of darkest gray (but not black). If there is a 1-pixel wide pattern pres-

ent, adjust “DMD Odd Pixel” offset for the current color. Stop when the pattern disap-

pears and the area is smooth.

5. Examine an area of lightest gray (but not white). If there is a 1-pixel wide pattern pres-

ent, adjust “DMD Odd Pixel” gain for the current color. Stop when the pattern disappears

and the area is smooth.

6. Repeat for each color, adjusting offset then gain for each.

NOTES: 1) Always adjust offset before gain, since offset affects gain. 2) A value of 128 repre-

sents no change in normal odd pixel offset or gain. 3) DMD Odd Buffer eliminates “1 pixel on, 1

pixel off” patterns only, not any type of larger patterns.

Advanced Color Temperature

Select the Advanced “Color Temp” option if you want to apply, alter, add, or copy a color tem-

perature, or if you want to use an unaltered factory default color temperature.

By default, the projector can utilize any of four calibrated factory-set color temperatures: 3200,

5400, 6500 or 9300 (expressed in degrees Kelvin). For most applications, these temperatures will

display accurate and realistic colors from a variety of sources. They can be selected at any time

in either the Image Adjustments menu or in the Advanced Color Temperature menu.

temperature created here is immediately applied, or it can be selected at any time from the Image

Adjustments menu as usual, regardless of your source or channel. The Color Balance Setup menu

options are described below.

NOTE: For best results, use an internal grayscale test pattern when working with color balance.

SET COLOR BALANCE - See Color Balance Setup Menu above. Upon opening the Color

Balance Setup menu, the current temperature appears as the top option. You can change to a dif-

ferent color temperature here as desired, just as in the Image Adjustments menu. Note that if you

select a "Custom" color temperature, the "White Level" options further down in the Color

Balance Setup menu are no longer disabled-you can adjust them as desired to define or change a

"Custom" color temperature (see "White Levels", below). Likewise, selecting "Infinite

Adjustable" here activates the "Infinite Adjustable" slidebar for defining or changing color tem-

perature.

INFINITE ADJUSTABLE - Select this option if you need a specific color temperature that lies

somewhere between one preset color temperature and another. Adjust the slidebar to define a new

temperature that will be adjusted from the neighboring presets (for example, 7841 is interpolated

from 6500 and 9300). It can be used any time and appears as a 4-digit temperature when present.

WHITE LEVELS -These 3 controls are adjustable only if a "Custom" choice is selected (in

which case "Custom 1, 2, 3 or 4" appears at the top of the Color Balance Setup menu). Their cur-

Lamp Adjust submenu

From the Advanced menu, select the "Lamp Adjust" option for access to the Lamp Adjust sub-

menu, where all lamp functions and data appear. Read-only information includes the number of

hours logged on the lamp so far and the serial number

recorded for the installed lamp.

XENON LAMP HOURS shows the number of hours logged on the current lamp. Whenever you

record a new lamp serial number, this value automatically resets to "0", where it begins to log time

for the new lamp. Note: Read-only. This information also appears in the Information menu.

New XENON Lamp Serial No. is the serial number recorded for the current lamp. When you

install a new lamp and enter its serial number, the number will appear here in the Xenon Adjust

menu. Note: Read-only.

Enter a checkmark for LAMP MESSAGE if you want to enable a warning message upon power-

up that the lamp has reached the specified lamp limit and should be replaced. Delete the check-

mark if you do not want to see this warning-instead, when your lamp expires, only the status

information on the back of the projector will provide the warning to replace the lamp.

NOTES: 1) It is recommended that the Lamp Message checkbox remain enabled. 2) When a lamp

warning message appears, press to temporarily cancel the message. The message will continue

to appear upon power-up until you install a new lamp.

Set XENON LAMP LIMIT to the number of hours you expect to log on the current lamp before

replacing it. The recommended limit is 1000 hours. At lower power settings, 2000 hours is pos-

sible.

NOTE: 1) If you change modes over the life of a lamp, the lamp limit you originally expected

may no longer be possible. 2) Turning the lamp on and off reduces lamp life significantly, as do

other factors.

Set which XENON LAMP MODE you want to use in order to control

the light output. Although there are exceptions, in most lamps, the high-

er the light output or power setting, the shorter the life span of the lamp.

OPERATION

Use the lamp mode that best suits your brightness needs. For example, in a tiled application you

may want to precisely match brightness levels between adjacent images-choose Intensity for each

projector, then judge by eye and set each individual intensity setting as necessary (see "Constant

Intensity", below). Or you may simply always need as much brightness as possible-choose Max

Output.

Lamp modes are described below:

ꢀ

Max Output: The lamp will always burn as brightly as possible, driven by maximum

power of 700W (VX-4c) and 1200W (VX-6c). Keep in mind that the "maximum bright-

ness" for any lamp gradually diminishes with age - the image will become dimmer over

time. Its current output level appears in the "Constant Intensity" option (not in lumens).

Constant Intensity: Brightness will remain at a specified level for as long as possible.

Once you select this option, enter a number representing the intensity level (brightness) you

wish to maintain. Note this value is a correlation only (0-9999), not actual lumen levels pos-

sible (0-3000, e.g.). See "Constant Intensity” below.

Constant Power: The power supplied to the lamp will remain at a desired watt level

throughout the life of the lamp. Once you select this option, enter the number of watts rep-

resenting the power level you wish to maintain. See "Constant Power" below.

CONSTANT POWER: The number shown here indicates how many watts are applied to the

lamp. Set from 450-700W (VX-4c) and 800-1200W (VX-6c) as desired, keeping in mind that

lower power levels produce dimmer images. When in "Constant Power" or Max Output modes,

the power level remains constant. When in "Constant Intensity" mode, the power level will

change as necessary. Specifying a power level of 700 is the same as operating in Max Output

mode.

NOTES: 1) Power level can be set only if the lamp is in "constant power" mode. 2) If you are in

"Intensity" mode, the power level value will automatically increase over time as necessary to

maintain the desired brightness, until power reaches 700W.

CONSTANT INTENSITY: This number is a representation of the current brightness of your

lamp, decreasing over time when you are operating at Max Output or at a specific Power level.

However, when you are operating in "Constant Intensity" mode, this value remains at the orig-

inal "IN" setting chosen.

NOTE: The number shown for "constnat intensity" is not the actual lumen output, but rather a

correlated value only-9999 may represent 3000 lumens, for example.

To use "Constant Intensity" mode, judge by eye and set the level as desired for your application,

remembering that higher settings can significantly shorten lamp life. Over time, the projector will

automatically increase the power supplied to the lamp as needed to maintain the chosen intensi-

ty to within 5% of the setting. This is called "brightness tracking".

3-36

Download from Www.Somanuals.com. All Manuals Search And Download.

OPERATION

Keep in mind that once the lamp power has reached its maximum of 700 watts (see "Constant

Power", above), this tracking is no longer possible. At this point, the lamp will gradually begin

to dim as usual, even though your original "Intensity" value will still appear in the menu. To

resume accurate tracking, reduce the intensity setting so that the resulting "Power" value is under

700 watts (VX-4c) and 1200W (VX-6c) - the lower the intensity, the longer it can be maintained.

Do not lower the "Intensity" so much that the corresponding "Power" value reaches its minimum

of 450 watts (VX-4c) and 800W (VX-6c) - the intensity setting will be inaccurate and cannot be

maintained.

NOTES: 1) Lamps become more stable over time, thus a specific intensity is more easily main-

tained as the lamp ages 2) Intensity can be set only if the lamp is in "Intensity" mode 3) Intensity

cannot exceed the output of Max Brightness mode.

3.8 Error Conditions

Occasionally the projector may encounter an error condition that interrupts normal operation.

Such a condition can be caused by an invalid user entry, an input signal error (most common) or

other system error.

If you would like to be notified on-screen of such errors, select the "Screen" option from the

"Display Error Messages" pull-down list (in OSD Settings menu). If you would like to be notified

via a serial communication only, select the "RS-232" option instead. To receive both notifications,

select "All". To disable error messages (except for invalid user entries), select "Off".

NOTE: Error messages also always appear at the rear LCD next to the keypad.

Invalid User Entry

Any keypad entry not recognized by the projector will trigger an on-screen error message describ-

ing the problem. For example, if you specify a channel number that has not been defined, the mes-

sage "Invalid Channel” will appear. Or if you try to enter the wrong password, you'll see "Invalid

Exit

Enter

Password". Press

to confirm the message and eliminate the message box.

NOTE: Displaying of "Invalid User Entry" messages cannot be disabled, even if Display Error

Messages has been set to "Off".

Input Signal Error

Input signal errors messages appear when there are no menus present, and have selected an input

on which the projector detects a problem. While menus remain operational and pressing any key

will temporarily remove the message from the screen, you must resolve the signal problem in

order to permanently eliminate the message.

NOTE: Input signal messages appear on-screen only if Display Error Messages has been set to

"Screen" or "All".

3-38

OPERATION

No Signal

The message "No signal" appears when there is no signal detected at the selected input. Both

HSYNC and VSYNC are inactive and the screen background is black. Connect or correct the sig-

nal, or select another input.

On the IR remote or wired keypad, press to display the projector box. Press again without enter-

ing a number - the keypad commands will now affect all projectors.

Make certain that only one projector has its "Broadcast Keys" option selected (checked) - the

remaining projectors should have the option unchecked and their keypads disabled (do this in

Preferences menu). The "Broadcast Keys" projector will then relay keypad commands to the oth-

ers. If using a wired remote, make sure to select the "Broadcast Keys" option for the projector to

which the wired remote is connected.

NOTE: If you are using a computer or controller to issue commands, use the correct RS-232 soft-

ware command to broadcast.

Bad Sync

The message "Bad Sync" is displayed when HSYNC or VSYNC are active but the signal cannot

be displayed. Such a condition occurs when only one of the two signals is present, or when either

signal is unstable or of the wrong frequency. Correct the signal or select another input.

Other Signal Error Messages

In addition to the common "Bad Sync" and "No Signal" errors, you may encounter a signal error

message indicating that Hsync and/or Vsync are either too fast or too slow. When such a message

appears, check the frequencies shown in the Information menu. If they are correct, then the sig-

nal may be out of the projector's operating range. On some PCs you may be able to change the

settings to generate a compatible signal. If the frequencies shown in the Information menu are

incorrect, check the cabling to see where the problem is.

System Warnings / Errors

When the projector encounters a system malfunction, either a System Warning message or a

System Error message may appear. Both types of messages are accompanied by a steady red

"Power" LED and a flashing red-and-yellow error code on the "Status" LED. This condition indi-

cates the need for service by a qualified Runco service technician.

NOTE: System messages appear on-screen only if Display Error Messages has been set to

"Screen" or "All".

System Warnings

A system warning message indicates that a system malfunction has been detected (see Status LED

Codes, below). A system warning message replaces any input signal message and disappears

when the input signal status changes. While the projector will remain operational, the message

indicates the presence of a serious problem that should be reported to the manufacturer. You can

Exit

press

to remove the message, but for best results you should reset the projector-power the

OPERATION

System Errors

A system error message indicates that a serious malfunction has been detected and must be

reported to the manufacturer (see Status LED Codes, below). The projector will no longer oper-

Power

ate and must be reset-power the projector down and up again with the

key.

The Status LED Codes

If the "Status" LED on the back of the projector repeatedly flashes a pattern of yellow and red

light while the "Power" LED glows a continuous red, you have encountered a likely system error

requiring the attention of a qualified service technician (see System Warnings and System Errors,

above). Try resetting the projector by powering it off and on again, cooling when necessary.

Consult Table 1 and contact your Runco Dealer if the problem persists.

The specific pattern of flashing indicates the 2-digit code identifying the type of problem encoun-

tered-the number of yellow flashes represents the first digit and the number of red flashes indi-

cates the second digit. For example, a pattern of "yellow-yellow-red-red-red" is "Code 23", mean-

ing the lamp ballast (power supply) is overheated. These codes include (see next page):

Maintenance

4.1

Warnings and Guidelines

This projector is CSA approved and is designed for safe and reliable operation. However, safe

operation cannot be assured by design alone; installers, maintainers, and users must maintain a

safe operating environment for the system. Please read through and understand the following

warnings and guidelines promoting safe usage of the projector.

! WARNING

Never look directly into the projector lens.

The extremely high brightness of this projector

can cause permanent eye damage.

! WARNING

For protection from ultraviolet radiation,

keep all projector shielding intact during operation.

Labels and Markings

Observe and follow all warnings and instructions marked on the projector.

The exclamation point within the equilateral triangle alerts the user to important

operating and maintenance (servicing) instructions in the literature accompanying

the projector.

The lightning flash and arrowhead symbol within the equilateral triangle alerts the

user to non-insulated "dangerous voltage" within the projector's enclosure that

may be of sufficient magnitude to constitute a risk of electric shock.

Projector Location

Operate the projector in an environment that meets the operating range specifications in Section

5, Specifications. Do not operate the projector close to water, such as near a swimming pool.

Do not place the projector on an unstable cart, stand or table. If the projector is to be ceiling

mounted, only use a Runco-approved ceiling mount fixture.

A projector and cart combination should be used with care. Sudden stops, excessive

force, and uneven surfaces may cause the projector and cart combination to overturn.

MAINTENANCE

Lamp and Filter Replacement

LAMP: Do not operate the Xenon lamp for more than 1000 hours; risk of the lamp shattering

increases as a result of changes in the quartz glass. Also, operation beyond 1000 hours signifi-

cantly reduces brightness output.

WARNING

Never attempt to remove the lamp housing directly after use.

The lamp is under great pressure when hot and may explode,

causing personal injury and/or property damage.

Allow to cool completely.

The arc lamp operates at a very high temperature and pressure. Failure to

allow the lamp to sufficiently cool prior to handling could result in an

explosion causing personal injury and/or property damage. After turning

the projector off it is important that you wait at least five minutes before

unplugging it. This provides enough time for the internal lamp cooling

fans to cool the lamp and to automatically shut off. Cool completely

before handling.

WARNING

Use only lamps supplied by Runco.

FILTER: Replace the side filter every 1000 hours or sooner. If this filter is not replaced, air flow

may become restricted and cause the projector to overheat.

See 2.2, Replacing the Lamp and Filter for the complete replacement procedure.

WARNING

Use only filters supplied by Runco.

Power Cord and Attachments

Only use attachments or accessories recommended by Runco, such as the 13 amp high-current

rated power cord supplied. Use of other attachments or accessories with this projector may result

in the risk of fire, shock or personal injury.

! WARNING

Use only the AC power cord supplied.

Do not attempt operation if the AC supply and

cord are not within the specified voltage and power range.

Do not allow anything to rest on the power cord. Locate the projector where the cord cannot be

damaged by persons walking on it or objects rolling over it.

Operate the projector at the specified voltage only. Do not overload power outlets and extension

cords as this can result in fire or shock hazards. Runco recommends a dedicated AC circuit for

the projector itself.

4-2

Download from Www.Somanuals.com. All Manuals Search And Download.

MAINTENANCE

The projector is equipped with a three wire plug having a third (grounding) prong. This is a safe-

ty feature. If you are unable to insert the plug into the outlet, contact an electrician to have the

outlet replaced. Do not defeat the safety purpose of the grounding-type plug.

Ventilation

Before unplugging the power cord, make sure the internal lamp cooling fans have shut off. The

fans automatically shut off when the projector has adequately cooled down.

Slots and openings in the projector provide ventilation. To ensure reliable operation of the pro-

jector and to prevent overheating, these openings must never be blocked or covered. The projec-

tor should never be placed near or over a radiator or heat register. The projector should not be

placed in an enclosure unless proper ventilation is provided.

Do not push objects of any kind into the projector through the ventilation openings. They may

touch dangerous voltages or short-out components resulting in a fire or shock hazard. Do not spill

liquids of any kind into the projector. Should an accidental spill occur, immediately unplug the

projector and have it serviced by a qualified Runco service technician.

Servicing

If any of the following conditions exist, unplug the projector from the power outlet and refer serv-

ice to qualified Runco service personnel.

ꢀ

The power cord has been damaged.

The internal cooling fans do not come on when the projector is first turned on.

Liquid has been spilled into the projector.

The projector has been exposed to excessive moisture.

The projector does not operate normally.

The projector has been dropped or the case has been damaged.

Do not attempt to service the projector yourself. All servicing must be performed by a qualified

Runco service technician. If replacement parts are required, it is important that only Runco-

approved parts are used. Other parts may result in fire, electric shock or risk of personal injury.

4.2

Cleaning

Clean the projector when required. Before cleaning, always unplug the projector from the power

outlet.

Lens

To avoid the risk of scratching the lens, clean the lens only if absolutely required. A small amount

of dust on the lens will have very little effect on picture quality. If the lens must be cleaned, use

a DRY soft cotton cloth. Clean gently in a circular motion.

Lamp

It is important to never touch the glass surface of the lamp, as the oil imprint will seriously

degrade lamp performance. Should you accidentally touch the surface of the lamp, clean careful-

ly with a lint-free cloth moistened with isopropyl alcohol.

MAINTENANCE

Case

Clean the case with a soft dampened cloth. Use a mild commercial cleaner. Do not use liquid or

aerosol cleaners.

4.3

Replacing Keypad Batteries

The optional IR Remote Keypad uses four AA size, 1.5V batteries (preferably alkaline). To install

new batteries, open the battery compartment at the back side of the keypad by pulling on the

raised portion of the cover as shown below.

Replacing Keypad Batteries

Remove the old batteries and properly discard. Wait a minute or two and place the new batteries

in the compartment, orienting the positive/negative of each battery according to the labels in the

compartment. When batteries are in place, replace the cover by inserting its bottom edge first and

snapping the top into place. Do not force.

NOTE: Always wait a minute or two when replacing batteries so that the internal electronics dis-

charge and can recognize the change.

NOTE: For this procedure you will need a VX-4c/VX-6c Lamp and Filter Replacement Kit from

Runco.

The high brightness of your projector is provided by a 700 watt Xenon lamp permanently mount-

ed inside its own protective housing. When the bulb approaches 1000 hours of usage, this lamp

assembly should be replaced.

How Old is The Lamp?

The number of hours logged on the current lamp appears both in the Lamp Adjust submenu

(accessed through the Advanced menu) and the Information menu. In the Information menu, do

not confuse “Xenon Lamp Hours” with “Projector Hours”, which indicates the number of hours

logged during the ‘rental period’, in a situation where the VX-4c/VX-6c is to be rented for vari-

ous functions. In a permanent install, this would be of no consequence.

NOTE: As the lamp nears its limit (as set in Lamp Limit), a message can appear on screen to

warn that the lamp needs to be replaced. To make sure that this warning appears, enter a check-

mark in the Lamp Message checkbox located in the Lamp Adjust submenu.

3. The lamp may have reached the end of its life. Check the “Lamp Hours” via RS-232 request

‘lph?’.

Symptomꢀ The display is jittery or unstable...

CAUSE / REMEDY:

1. If the display is jittery or if it disappears and reappears erratically, check that the source is prop-

erly connected and that its signal is of adequate quality for detection. For example, it the projec-

tor scans the default input for a signal to display, and a poor quality or improperly connected

source is connected, the projector will briefly and repeatedly attempt to display an image. If no

source is connected, the “No signal present” error message appears over a blank display. Correct

the source connection.

2. The horizontal or vertical scan frequency of the input signal may be out of range of the pro-

jector. Refer to page 5-1, Specifications for scan frequency ranges.

3. The sync signal may be inadequate. Correct the source problem.

4. The input signal type may conflict with the input module. Install/use the correct module for the

source.

5. Pixel tracking, phase, filter, etc. may need more adjustment.

Symptomꢀ The display is faint...

CAUSE / REMEDY:

1. Check Input Levels option-turn auto to “off”, then “on” again.

2. Brightness and/or contrast may be set too low. Adjust as necessary.

3. Gamma may be set too low. Recommended setting for most signals is 2.2.

4. The projection room may be too bright. Lower the intensity of projection room lighting and

reduce light reflections as much as possible.

5. The projector may be too far from the screen. Move the projector closer.

MAINTENANCE

6. The location of the audience with respect to the screen may not be ideal. Make sure the audi-

ence is within the viewing angle set by the projector and screen position, and the screen type.

7. The source may be double terminated. Ensure the source is terminated only once.

8. The source (if non-video) may need sync tip clamping. Enter a check in the "Clamp Tip" box

found in the Input Levels submenu.

SymptomꢀThe display is reversed and/or upside-down…

CAUSE / REMEDY:

1. The projector's image orientation is not set correctly for the current installation. Refer to 2.6,

Operating Orientation to set the projector's image orientation to match your installation.

SymptomꢀThe upper portion of the display is waving, tearing or jittering…

CAUSE / REMEDY:

1. This can sometimes occur with video or VCR sources. If you are using a VCR, make sure that

the "VCR" option is checked (in Advanced menu).

SymptomꢀPortions of the display are cut off or wrap to the opposite edge…

CAUSE / REMEDY:

1. Reduce top, bottom, left or right blanking from within the Scaling Parameters menu. Check

size and position adjustments.

2. Resizing may need adjustment. Adjust until entire image is visible and centered.

SymptomꢀThe display appears compressed or stretched…

CAUSE / REMEDY:

1. The frequency of the pixel sampling clock is incorrect for the current source.

2. The Scaling Parameters options may be adjusted poorly for the incoming source signal.

See 3.6, Adjusting the Image.

SymptomꢀDisplay quality appears to drift from good to bad, bad to good…

CAUSE / REMEDY:

1. The operating temperature of the projector may be fluctuating. Watch that the projector is not

located too close to heating/air conditioning vents.

2. The source input signal may be of low quality.

3. The horizontal or vertical frequency of the input may have changed at the source end.

SymptomꢀThe display has suddenly frozen, or an unknown menu has appeared…

CAUSE / REMEDY:

Func

1. You may have accidentally entered a special engineering code using the

key in combi-

Exit

nation with certain numbers, or you may have selected the "Freeze Image" option. Press

necessary to cancel the function and return to presentation level.

2. If the screen blacks out inexplicably, it is possible that excessive voltage noise on the AC or

ground input has interrupted the projector's ability to lock on to a signal. Turn the projector off,

wait for the lamp fans to stop, and unplug. Plug in again and power up as usual.

SymptomꢀThe display is not sharp or "clean"…

CAUSE / REMEDY:

1. More display adjustment may be required-focus, brightness, contrast, pixel tracking, pixel

phase, and detail.

2. If you are using a BNC T-connector, try using a distribution amplifier to boost signal levels.

3. Is the video input signal properly terminated? Set in OSD Settings menu.

4. The screen size may be too large. As screen size increases, magnification increases, reducing

brightness and clarity. See lens specifications in Section 5.

5. The source input signal may be of low quality. Try another source.

MAINTENANCE

SymptomꢀColors in the display are inaccurate…

CAUSE / REMEDY:

1. The color, tint, gamma, color space and/or color temperature settings may require adjustment.

Review all settings, and refer to 3.6, Adjusting the Image and 3.7, Adjusting System Parameters

and Advanced Controls.

Symptomꢀ The display is not rectangular…

CAUSE / REMEDY:

1. Check leveling of the projector. If necessary, try relocating the projector or screen so that the

lens surface and screen are approximately parallel

2. Is the vertical offset set correctly? Adjust as necessary using the vertical offset knob on the

front of the projector.

3. The "Vertical Stretch" option may need adjustment. Also check pixel tracking.

SymptomꢀThe display is "noisy"…

CAUSE / REMEDY:

1. Display adjustment may be required. Adjust pixel tracking, phase and filter.

2. The video input may not be terminated. Make sure the video input is terminated (75 Ω). If it

is the last connection in a loop-through chain, the video input should be terminated at the last

projector only.

3. The signal cables carrying the input signal may be of poor quality. Use only good quality sig-

nal cables.

4. The distance between the input source device and the projector may be too great. If the dis-

tance between the input source device and the projector is greater than 25 feet, signal amplifica-

tion/conditioning may be required.

5. The input signal may be of poor quality.

6. If the source is a VCR or off-air broadcast, detail may be set too high. Keep near 4 for most

sources.

* ANSI Lumen Specification:

This is the typical projector luminosity (brightness) specification found in most sales literature. This measurement is

included in RUNCO literature to allow for direct comparison with other manufacturer’s projectors. These measurements

can be taken at 9,000° to 13,000° Kelvin to get expected performance data when the projector is used in professional,

commercial, and industrial displays.

CSMS Home Theater Calibration ANSI Lumen Specification:

These measurements are taken from the projector as set up in a home theater environment. The projector is calibrated

to ISF specifications including setting the color temperature to 6500° K, the standard for reproducing video.

CSMS Home Theater Calibration foot-Lambert (fL) Specification:

This is the unit of measurement used in commercial movie theaters to express image brightness. The Society of Motion

Picture and Television Engineers (SMPTE) specifies 16 fL as the target image brightness for film-based projectors using

an open gate (without film in the projector). More importantly, today SMPTE specifies 12 fL as the target image bright-

ness in Digital Cinema theaters using DLP™ technology. The foot-Lambert is dependant on screen size, screen gain,

and projector light output.

All measurements are made at RUNCO to ANSI/NAPM IT7.228-1997 specifications using the Photo Research PR-650

Spectra Colorimeter and Minolta LS-100 Luminance Meter, Video Essentials test DVD, and a Da-Lite 1.5 gain, 100-inch

wide screen. The projector is calibrated to a color temperature of 6500° Kelvin and has a minimum of 150 hours of

usage.

INTRODUCTION

General Description

Congratulations on your purchase of the VHD Ultra Controller video processor with Vivix™ technology! This

processor is designed to maximize the image quality of your fixed-pixel display or rear-screen television while

adding an extra level of flexibility to your system. The VHD Ultra Controller's Vivix™ processing techniques

enable this processor to be used most efficiently with fixed-pixel displays, and will provide the most stunning

image that your display can possibly deliver.

Vivix™ is a proprietary technique developed by Runco engineers to match the output resolution of the proces-

sor precisely to the display it will be used with. This precision processing technique resolves all the problems

that conventional video processors have with fixed-pixel displays, which include pixel-tracking

artifacts (jagged lines, moiré, jerky motion, etc.), too much overscan (significant loss of image) and even

improper and disproportionate aspect ratios. The results of Vivix™ technology is an image that nearly rivals

that of a CRT, while providing three geometrically-correct aspect ratios on a 16:9 or a 4:3 screen.

Features and Benefits

The VHD Ultra Controller have many great features and benefits that make it a flexible, high-quality

processor. Its many benefits include:

• Vivix^TMTechnology, which maximizes image quality and flexibility of fixed-pixel displays.

• An adaptive 2-dimensional comb filter that greatly reduces artifacts when using a composite video signal as

an input.

• A Luma edge enhancement circuit makes the edges of objects appear sharper without the ringing and

noise increase associated with traditional sharpness circuits

• A Chroma edge enhancement circuit is included to compensate for lower chroma resolution found in com-

posite and S-video.

• Inverse Telecine (3:2 pulldown) detection and processing allows the scaler to almost completely eliminate

interlace artifacts associated with other scalers

• The controller can correctly scale anamorphic, letterbox and 4:3 formats to fit on a wide aspect-ratio screen,

and scale anamorphic formats on a 4:3 screen

• A pass-through connector is supplied for routing HDTV or computer graphics directly to the display.

• An RS-232 input is provided for easy integration into the automated home theater environment

• A TBC (Time Base Corrector) circuit is provided for unstable sources such as VCR’s.

• 12V outputs are provided for drop screens and screen masking.

• A simple 7-button remote controls all aspects of operation. One button source selection and aspect ratio

control is also provided via the remote control.

While there are many different ways to connect your source equipment to your VHD Ultra Controller,

the examples shown above are the most common.

• COMPOSITE VIDEO INPUT:

Composite video is the most common type of signal used, but is also the lowest in picture quality. Many

sources have outputs that are limited to composite video, such as some VCR’s and camcorders; others

such as Laser Disc players actually produce slightly better results when using composite video.

• S-VIDEO INPUT

S-video is the second-best type of signal that can be used, but is MUCH better than composite video.

Using such sources as Satellite receivers, high-quality VCRs and DVD players (with no component

output) will produce a MUCH cleaner and sharper signal.

COMPONENT INPUT

Component video is the best type of signal that can be used. The most common sources that use com-

ponent outputs are DVD players, and it is highly recommended that component be used when possible.

Component video goes one step beyond S-video in picture quality; chroma (color) information is more

resolved and the overall picture appears more well-defined.

• PASS-THROUGH

This input is used to ‘pass-through’ any high-definition or computer signals that do not require process-

ing. The signal by-passes the VHD Ultra Controller’s processing and is sent directly to the display. The

pass-through may be used for COMPONENT outputs from a DTV decoder, a progressive-scan DVD play-

er or RGB outputs from a computer or other high-resolution sources.

and highlight the desired source, and press ENTER. Otherwise, you may select a source by pressing

either the left or right arrow buttons (on the remote or front panel) when no menus are

on-screen, or by pressing one of the direct access buttons on the remote control (recommended; see page

6-8).

If pass-through is selected, note that no on-screen menus will be displayed since the signal is simply

being 'looped' directly to the output. When pass-through is the selected source, pressing MENU will auto-

matically select the last selected input before Pass-through was selected. If you wish to choose another

source, Runco recommends using the direct access buttons to select the desired source as opposed to

pressing MENU.

Aspect Ratio provides selection of one of three aspect ratios: Anamorphic, Letterbox or standard 4:3. To

select an aspect ratio via the main menu, press either the up and down buttons on the remote or front

panel, highlight ASPECT RATIO and press ENTER. The aspect ratio menu will then appear with the three

choices; highlight the desired aspect ratio with the up or down buttons and press ENTER. Otherwise, you

may select an aspect ratio by pressing either the up or down arrow buttons (on the remote or front panel)

when no menus are on-screen, or by pressing one of the direct access buttons on the remote control (rec-

ommended; see page 6-8).

Installation is where the image shift and blanking controls are located. A full description of this menu is

on page 6-13.

NOTE: If INSTALLATION does not appear on the main menu, see page 6-13 for an explanation on how

to access the Installation menu.

Picture quality adjustments (also known as "Front Panel Controls") are the controls that change different

parameters of the image such as the amount of color, black level, etc. While these adjustments can be set to suit

the needs of the user, there is a way to set these properly. This section will describe what each function does and

how to adjust them properly.

To access the picture quality adjustments, press MENU, highlight the active source (indicated by the arrow) and

press ENTER. The picture quality sub-menu will then appear (see above).

To make an adjustment to a particular function, highlight the function with the up or down arrow buttons and press

ENTER. Once the function is on-screen (i.e. brightness), pressing the UP arrow button on the remote or front panel

will increase the value of that function; pressing the DOWN arrow on the remote or front panel will decrease the

value of that function.

While each of the picture quality adjustments can be set to suit the needs of the user, there is a 'proper' way to set

the adjustments. For setting TINT and COLOR, please refer to the color bar test pattern below.

NOTE: Runco recommends that a BLUE FILTER be used so only the blue color bars can be seen. Blue filters are

provided with the Video Essentials or AVIA test DVDs, or can be purchased from the Imaging Science Foundation

(www.imagingscience.com).

TINT (also known as 'hue') is essentially the ratio of red to green in the color portion of the image.

If TINT is decreased, the image will appear redder, and increasing it will cause the image to appear green-

er. To set TINT properly, look at the color bar pattern through a blue filter (or mute the red and green out-

puts). Adjust TINT until the middle two tall color bars match the middle short color bars

(see color bar drawing).

COLOR (also known as 'saturation') increases or decreases the amount of color in the image. To set

COLOR properly, look at the color bar pattern through a blue filter (or mute the red and green outputs).

Adjust COLOR until the outer two tall color bars match the outer short color bars

(see color bar drawing).

For setting CONTRAST and BRIGHTNESS, please refer to the PLUGE pattern below:

Set contrast

untill there is

no 'blooming'

in this bar.

Below black

Above black

CONTRAST adjusts the white level of the image. To adjust this properly for CRT projectors, adjust CON-

TRAST until there is no blooming (or distortion) in the brightest bar in the PLUGE pattern (see above).

For Fixed-pixel displays, adjust contrast until there is a distinct definition between the two brightest bars.

NOTE: For best results, Runco recommends that CONTRAST be set to '0' or very close to it.

BRIGHTNESS adjusts the black level of the image. To adjust this properly, adjust BRIGHTNESS until the

'below black' bar JUST disappears, but the 'above black' bar is still barely visible.

NOTE: Some DVD players cannot pass the 'blacker than black' bar (they won't pass PLUGE), and that

bar will never be visible. In a case like this, adjust the 'above black' bar until it is slightly brighter than the

background that surrounds it.

SHARPNESS adjusts the amount of high-frequency detail in the image. This can be adjusted to the pref-

erence of the user. Keep in mind that when SHARPNESS is decreased, fine details in the image will

become 'soft'; when it is increased, fine details will become sharper but will also make the picture appear

'noisy' if adjusted too high.

LUMA ENHANCE acts as an edge enhancement, especially around black to white transitions in the

image. Essentially, this has the same characteristics as sharpness but affects the edges of objects far

more that the rest of the image.

FREQUENCIES HIGH/LOW affect the overall range of the LUMA ENHANCE feature. For example, if

using a lower-quality video source such as a VCR, the FREQUENCIES should be set to LOW. For a good

quality source such as a DVD player, set FREQUENCIES to HIGH. To set FREQUENCIES, press ENTER

while LUMA ENHANCE is on-screen.

CHROMA ENHANCE acts as an edge enhancement, especially around color transitions in the image.

Essentially, this has the same characteristics as sharpness but affects the edges of objects far more that

the rest of the image.

Installation Menu

The Installation menu is where you can adjust the type of screen (4:3 or 16:9), shift the image or set blank-

ing.

When the VHD Ultra Controller is turned on for the first time, the INSTALLATION item will not appear in

the main menu. To enable the INSTALLATION menu, there are two options:

· With the processor ON and no menus on-screen, simultaneously press the ENTER, UP and LEFT

buttons (you don't need to hold them down). Release the three buttons and press MENU, ensure INSTAL-

LATION is now on the bottom of the main menu.

· With the remote control, press button 6 (with no menus on-screen). After pressing '6', press MENU and

ensure INSTALLATION is now on the bottom of the main menu.

After INSTALLATION has been accessed, press MENU, highlight INSTALLATION and press ENTER.

This will bring up the INSTALLATION MENU, shown below:

Screen Type

When you are installing the system for the first time, the first order of business is to define what type of screen

will be used with this system. If a 1.78:1 (16:9) or 1.85:1 screen is used, highlight 16:9 SCREEN and press

ENTER. If a standard 4:3 screen is installed, highlight 4:3 SCREEN and press enter.

The purpose of defining the screen type is to tell the processor how to create aspect ratios (see page 6-16 for

a definition of aspect ratios). For example, on a 16:9 screen, the letterbox and anamorphic aspect ratios will

use the entire 16:9 screen, and the 4:3 aspect ratio will be displayed in the center of the 16:9 screen (you'd

have 'black bars' on the left and right sides of the image).

On the other hand, on a 4:3 screen, the 4:3 aspect ratio would fill the screen, but the letterbox and

anamorphic aspect ratios would be displayed in the center of the screen vertically (there would be 'black bars'

on the top on bottom of the image).

Image Shift

IMAGE SHIFT moves the entire image up, down, left or right. If the image is slightly off-center on-screen

after installation, using IMAGE SHIFT can center the image on your screen or display.

While using IMAGE SHIFT will not cause any problems with your display, it is possible to use too much

image shift, which could cause the image to shake or disappear. Therefore, Runco recommends that

image shift be done with the display device itself whenever possible.

Blanking

The BLANKING function allows you to 'cut off' part of the image to fit the screen properly, or to eliminate

anomalies on the extreme outsides (usually the top) of the image. This can be done to the top, bottom,

left or right sides individually.

To adjust BLANKING, highlight the desired area you wish to blank (top, bottom, left or right), and use the

left and right arrows to make the adjustment.

Most CRT projectors themselves have blanking controls, and it is recommended that you use the

controls on the projector as opposed to the processor, if possible. In the event that your display device

does not have blanking controls, however, use the blanking controls provided in the processor.

System Reset

In the event that your VHD Ultra Controller appears to have a software problem, or adjustments have

been made so far out of range that the image is no longer on-screen or discernable, you can reset the

processor back to factory values. This sets ALL settings back to factory values, so any adjustments made

previously will be lost.

To reset your VHD Ultra Controller, follow this procedure:

Turn off the MAIN POWER switch on the back of the processor

Hold down the DOWN ARROW button, and turn the MAIN POWER SWITCH back on.

Continue holding the down arrow button until the LED on the front panel blinks, then release

the down arrow button.

Once this is done, your processor has been completely reset to factory values.

After resetting the unit, Composite video will be the active source.

SYSTEM RESET is not on any of the menus; it must be performed using the instructions above.

ASPECT RATIOS

FREQUENCIES HIGH/LOW affect the overall range of the CHROMA ENHANCE feature. For example, if

using a lower-quality video source such as a VCR, the FREQUENCIES should be set to LOW. For a good

3 units tall

4 units wide

quality source such as a DVD player, set FREQUENCIES to HIGH. To set FREQUENCIES, press ENTER

while CHROMA ENHANCE is on-screen.

An ‘aspect ratio’ is simply the ratio of the width vs. the height of the screen. For example, the current aspect

ratio standard is 4:3 (or 1.33:1), where the image is 4 units wide and 3 units tall.

All of our ‘regular’ televisions are this aspect ratio. You have probably noticed that occasionally you’ll watch

a movie that does not fill the screen vertically. This is because the movie was filmed in WIDESCREEN

(letterbox), and the result is ‘black bars’ above and below the image:

Obviously, watching a movie like this does not lend itself to a truly cinematic experience! This is why

Runco invented the first-ever multiple aspect-ratio projection system back in 1991, so true movie-lovers

can watch actual widescreen (letterbox) movies on a WIDESCREEN!

areas

A WIDESCREEN can be a number of aspect ratios; many movies are either 1.85:1 or 2.35:1, and HDTV

is always 1.78:1 (16:9). The way we create a widescreen (or LETTERBOX) aspect ratio is to take a full

4:3 image, then ‘blank’ (or cut off) the top and bottom so the displayed image is in a widescreen format.

For movies recorded in ‘letterbox’, there would be no information above and below the screen anyways,

so we’re not losing any of the picture. However, if you were to watch standard television broadcast this

way, you would lose some information (see next drawing).

As you can see, our screen in this example is a 1.85:1 ratio. The dashed lines show the area that we

‘blanked’. If you recall, watching a letterbox movie on a 4:3 screen gave us black bars; therefore with let-

terbox movies, we’re not losing any information!

The ‘other’ type of widescreen is called ‘ANAMORPHIC’. The image is still a widescreen format, but

instead of ‘blanking’ the top and bottom, we simply reduce the overall height of the image:

As a result, all objects will be ‘short and fat’ (like the circle above), right? Well, not if you’re using

software that is anamorphic. Most (but not all) DVD movies have an anamorphic option.

Anamorphic material will always produce a better image when using a high quality scaler such as the VHD

Ultra Controller. The reason is that you will actually get more lines of resolution (and ultimately more

Command format (single command): command value (i.e. brightness 30).

NOTE: A space (not an underscore) must be used between the command and its value.

All Commands must be followed by a carriage return.

Command string format: command,command value, command etc.

(i.e. COMPOSITE,BRIGHTNESS 30,ANAMORPHIC)

NOTE: In between commands, a comma or space can be used; a space must be used in

between a command and its value. All commands must be followed by a carriage return.

Other notes:

· All Commands must be followed by a carriage return.

· For command strings, a maximum of 255 characters can be used in a single string.

· If it is necessary to input multiple commands, they should all be together in a single string.

Inputting commands one at a time requires an arbitrary delay between commands while the

commands are being executed. Therefore, programming requires delays and is more difficult.

· For values not automatically stored (see next paragraph), the command "!STORE" must be

sent in order for the VHD Ultra Controller to keep the settings. Otherwise, the values will be

considered temporary and will revert to their stored settings upon source change or power-up.

· The "Value stored" column refers to a command that is either automatically stored or if it must

be manually stored with the "!STORE" command.

· PARAMETER min/max refers to a function's minimum and maximum value range. Inputting

values above or below their range may cause unpredictable (but not fatal) results.

· After each command is entered, the Controller returns the “>” symbol as a prompt

(ASCII code Ox). Use this symbol as an acknowledgement if your control system requires it.

Appendix A

Glossary

This appendix defines the specific terms used in this manual as they apply to this projector. Also included are

other general terms commonly used in the projection industry.

Active Line Timeꢀ

The time, inside one horizontal scan line, during which video is generated.

Ambient Light Rejectionꢀ The ability of a screen to reflect ambient light in a direction away from the "line

of best viewing". Curved screens usually have good ambient light rejection. Flat

screens usually have less ambient light rejection.

Analog Videoꢀ

The video output of most computers and video tape machines. Analog video can

generate a large number of colors.

Aspect Ratioꢀ

The ratio of the width of an image to its height, such as the 4:3 aspect ratio com-

mon in video output.

Auto Sourceꢀ

The ability of the projector to automatically recognize and synchronize to the hor-

izontal and vertical scan frequencies of an input signal for proper display.

Bandwidthꢀ

The frequency range of the projector's video amplifier.

Baud Rateꢀ

The speed at which serial communications travel from their origin. In this projec-

tor, the RS-232 or RS-422 default baud rate of 38400 can be changed to match a

controlling device.

Blanking Timeꢀ

The time inside one scan line during which video is not generated. The blanking

time of the input signal must be equal to or greater than the retrace time of the pro-

jector.

Brightnessꢀ

In projection, brightness usually describes the amount of light emitted from a sur-

face such as a screen. It is measured in foot-lamberts or candelas per square meter.

Candela or Candleꢀ

Unit of measure for measuring intensity of light.

Channelꢀ

A collection of measurements stored by the projector for a given input source,

including frequencies, pulse width, polarity, syncs, channel number and location,

user-adjustable display settings, etc. Use channels to switch between a variety of

setups quickly, automatically recalling previously defined display parameters.

Channel Listꢀ

A list/menu of previously-defined channels available in projector memory.

Channel Numberꢀ

A number that uniquely identifies a specific channel retained in projector memo-

ry. The projector can retain up to 99 channels.

GLOSSARY

Checkboxꢀ

A menu item that indicates whether an option is currently in effect (checked) or

not (unchecked).

Color Shiftꢀ

A change in the color of a white field across an image (white field uniformity).

Color Temperatureꢀ

The coloration (reddish, white, bluish, greenish, etc.) of white in an image, meas-

ured using the Kelvin (degrees K) temperature scale. Higher temperatures appear

bluer, while lower color temperatures appear redder.

Component Videoꢀ

See YCbCr or YPbPr.

Composite Videoꢀ

The output of video tape players and some computers, characterized by synchro-

nization, luminance and color signals combined on one output cable.

Contrast (ratio)ꢀ

Convergenceꢀ

The degree of difference between the lightest and darkest areas of the image.

The alignment of the red, green, and blue elements of a projected image.

Curved Screenꢀ

A projection screen which is slightly concave for improved screen gain. Curved

screens usually have screen gains which are greater than 1 but viewing angles

much less than 180°. Curved screens are not recommended for use with this pro-

jector.

DDIꢀ

A Direct Digital Interface signal can be supplied to the projector via an optional

digital input module installed in INPUT 2. For example, you can input an SMPTE-

259M signal using a Serial Digital Input Module or input an SMPTE-272M signal

from a HDTV Serial Input Module.



DMD ꢀ

Digital Micromirror Devices used in this projector for processing red, green, and

blue color data.

Decoderꢀ

Located at INPUT 3 and INPUT 4, this device converts NTSC 3.58, NTSC 4.4,

PAL, PAL-N, PAL-M, or SECAM to RGB video.

Detailꢀ

The sharpness of a display from a video source.

Diffused Screenꢀ

A type of rear-projection screen which spreads the light striking it. Screen gain is

less than 1 but audience viewing angles are increased.

Display Settingꢀ

Flickerꢀ

An adjustment that affects the display of an image. Such display settings include

contrast, brightness, tint, blanking, size, offsets, and others.

A very rapid variation in image brightness caused by a frame rate that is too slow.

(See Interlace.)

Frame Rateꢀ

The frequency at which complete images are generated. For non-interlaced sig-

nals, the frame rate is identical to the vertical frequency. For interlaced signals, the

frame rate (also known as field rate) is one half of vertical frequency.

Foot-candleꢀ

The intensity of visible light per square foot.

Foot-lambertꢀ

The luminance (brightness) which results from one foot-candle of illumination

falling on a perfectly diffuse surface.

Gain or Screen Gainꢀ

The ability of a screen to direct incident light to an audience. A flat matte white

wall has a gain of approximately 1. Screens with gain less than 1 attenuate inci-

dent light; screens with gain more than 1 direct more incident light to the audience

but have a narrow viewing angle. For example: An image reflecting off a 10 gain

screen appears 10 times brighter than it would if reflected off a matte white wall.

GLOSSARY

Curved screens usually have larger gain than flat screens.

Help Screenꢀ

A display of help information regarding the current task or presentation.

Horizontal Frequencyꢀ

The frequency at which scan lines are generated, which varies amongst sources.

Also called horizontal scan rate or line rate.

Horizontal Offsetꢀ

The difference between the center of the projected image and the center of the pro-

jector lens. For this projector, this value is expressed as the maximum percentage

of the image that can be projected to one side of the lens center without degrading

the image quality. Horizontal offset ranges can be affected by the type of lens in

use, and whether or not the image is offset vertically at the same time.

Hot Spotꢀ

A circular area of a screen where the image appears brighter than elsewhere on the

screen. A hot spot appears along the line of sight and "moves" with the line of

sight. High gain screens and rear screens designed for slide or movie projection

usually have a hot spot.

Inputꢀ

A physical connection route for a source signal, described by a 2-digit number rep-

resenting 1) its switcher/projector location and 2) its slot in the switcher/projector.

Input Signalꢀ

Signal sent from a source device to the projector.

Interfaceꢀ

A device, such as the Serial Digital Input Module, that accepts an input signal for

display by the projector.

Interlaceꢀ

A method used by video tape players and some computers to double the vertical

resolution without increasing the horizontal line rate. If the resulting frame/field

rate is too low, the image may flicker depending on the image content.

Keypadꢀ

A small push-button device for controlling most projector settings and operation.

For more information, refer to 3.3, Using the Keypad.

Keystoneꢀ

A distortion of the image which occurs when the top and bottom borders of the

image are unequal in length. Side borders both slant in or out, producing a key-

stone shaped image. It is caused when the screen and lens surface are not parallel.

Linearityꢀ

The reproduction of the horizontal and vertical size of characters and/or shapes

over the entire screen.

Line of Best Viewingꢀ

When light from a projector is incident on a screen, the light reflects from the

screen such that the angle of reflection equals the angle of incidence. The Line of

Best Viewing is along the line of reflection.

Loop throughꢀ

The method of feeding a series of high impedance inputs from a single video

source with a coaxial transmission line in such a manner that the line is terminat-

ed with its characteristic impedance at the last input on the line.

Lumenꢀ

The unit of measure for the amount of visible light emitted by a light source.

Luxꢀ

The amount of visible light per square meter incident on a surface.

1 lux = 1 lumen/square meter = 0.093 foot-candles

GLOSSARY

Menuꢀ

A list of selectable options displayed on the screen.

NTSC Videoꢀ

A video output format of some video tape and disk players. There are two types of

NTSC (National Television Standards Committee) video: NTSC 3.58 and NTSC

4.43. NTSC 3.58 is used primarily in North America and Japan. NTSC 4.43 is less

commonly used.

Optical Screenꢀ

PAL Videoꢀ

A type of rear-projection screen which re-directs light through the screen to

increase image brightness in front of the screen. Screen gain is usually greater than

1 but audience viewing angles are reduced.

PAL (Phase Alternating Line) video is a 50 Hz standard with 768 x 576 resolution.

It is found on some video tape and disk players (used primarily in Europe, China

and some South American and African countries).

Pincushionꢀ

A distortion of the image shape characterized by concave or convex borders.

Pixel (picture element)ꢀ The smallest discernible element of data from a computer-generated image.

Pixel Phaseꢀ

The phase of the pixel sampling clock relative to incoming data.

Pixel Trackingꢀ

The frequency of the pixel sampling clock, indicated by the number of pixels per

line.

Projector-to-Screen Distanceꢀ

The distance between the projector's front feet centers and the screen. Also called

"Throw Distance".

Protocolꢀ

The type of code format called "A" or "B" utilized by the remote keypad(s). The

default protocol set at manufacture is Protocol "A". By using two different keypad

protocols, adjacent projectors can be controlled independently with their remote

IR keypads.

Pull-down Listꢀ

A selectable menu item that unfolds into a list of options pertaining to it.

Rear Screenꢀ

A translucent panel for screen projection. Incident light travels through the inci-

dent surface of a rear screen and forms an image on the other surface.

Resizingꢀ

The ability to manipulate through software commands the physical size, placement

and/or aspect ratio of an image.

Resolution (lens)ꢀ

The maximum number of alternate white and black horizontal lines that can be dis-

tinguished on a screen when a photographic target is placed between the lens and

a light source and illuminated by that source.

Resolution (projector)ꢀ

Retrace Timeꢀ

The maximum number of pixels that the projector can display horizontally and

vertically across an image, such as 1280 x 1024.

(Horizontal) The minimum time required for a CRT projector to move the position

of the scanning spot from the right edge to the left edge.

GLOSSARY

RGB Videoꢀ

The video output (analog or digital) of most computers. Analog RGB video can have 3, 4,

or 5 wires - one each for red, green, and blue, and either none, one or two for sync. For

three-wire RGB, the green wire usually provides sync. (See TTL Video).

RS-232ꢀ

RS-422ꢀ

S-Videoꢀ

A common asynchronous data transmission standard recommended by the Electronics

Industries Association (EIA). Also called serial communication.

A less common asynchronous data transmission standard in which balanced differential

voltage is specified. RS-422 is especially suited to long distances.

The output from certain video tape players and video equipment. S-Video separates sync

and luminance from color information, typically producing a higher quality display than

composite video.

Scan Frequencyꢀ The horizontal or vertical frequency at which images are generated.

Scan Lineꢀ

One horizontal line on the display.

SECAMꢀ

A video output format of some video tape and disc players (used primarily in France).

SECAM (Sequential Couleur á Mémoire) signals are similar in resolution and frequency

to PAL signals. The primary difference between the two standards is in the way color

information is encoded.

Slidebarꢀ

A slidebar is a graphical display of an adjustable setting. The numerical setting often rep-

resents a percentage but can be a specific unit such as degrees Kelvin.

Sourceꢀ

The device, such as a computer or VCR, connected to the projector for display. A source

Input1

is identified at the projector as

, or

, or as other user-defined num-

bers. A source may have numerous corresponding channels defined and recognized by the

projector. See Input.

Source Setupꢀ

See Channel.

Spot Sizeꢀ

The diameter of the smallest dot that can be generated by a CRT projector. This projector

has a fixed spot (pixel) size.

Syncꢀ

This term refers to the part of the video signal that is used to stabilize the picture. Sync

can occur in three forms:

1) "Composite sync": the horizontal and vertical components are together on

one cable.

2) "Sync-on-green": the sync is part of the green video.

3) "Separate sync" or "H.SYNC and V.SYNC": the horizontal and vertical

components of the sync are on two separate cables.

Sync Widthꢀ

The duration of each sync pulse generated by a computer. The sync width is part of the

blanking time.

TTL Videoꢀ

A type of RGB video with digital characteristics.

Terminatedꢀ

A wire connecting a single video source to a display device, such as a projector, must be

terminated by a resistance (usually 75Ω for video).

GLOSSARY

Throw Distanceꢀ The distance between the front feet of the projector and the screen. Also called "Projector-

to-Screen Distance". Always use the correct throw distance formula to calculate the prop-

er throw distance (±5%) required for your lens.

Tintꢀ

Balance of red-to-green necessary for realistic representation of NTSC signals.

Variable Scanꢀ

The ability of a projector to synchronize to inputs with frequencies within a specified

range.

Vertical FrequencyꢀThe frequency at which images are generated. Vertical frequencies vary amongst sources.

Also called vertical scan rate.

Vertical Offsetꢀ

The difference between the center of the projected image and the center of the projector

lens. For this projector, this value is expressed as the maximum percentage of the image

that can be projected above or below the lens center without degrading the image quality.

Vertical offset ranges depend on the type of lens in use, and whether or not the image is

offset horizontally at the same time.

Videoꢀ

The signal that is used by display devices (such as projectors) to generate an image. This

term also refers to the output of video tape/disk players and computers.

Video Decoderꢀ

An optional device that converts NTSC 3.58, NTSC 4.4, PAL, PAL-N, PAL-M or SECAM

to RGB video.

Video Standardꢀ A specific type of video signal, such as NTSC, PAL, SECAM. This projector can auto-

matically recognize and interpret the incoming standard and display accordingly.

Viewing Angleꢀ

Screens do not reflect equally in all directions. Most light is reflected in a conical volume

centered around the "line of best viewing". Maximum brightness is perceived if you are

within the viewing cone defined by the horizontal and vertical viewing angles.

White Balanceꢀ

The color temperature of white used by the projector.

White Fieldꢀ

The area of an image that is white only. For example, a full white field is an image that is

white everywhere. A 10% white field is a white area (usually rectangular) that occupies

10% of the image; the remaining 90% is black.

YCbCrꢀ

A high-end digital component video signal.

YPbPrꢀ

A high-end analog component video signal. Sometimes called YUV, Component, or Y, R-

Y, B-Y, the YPbPr signal by-passes the video decoder in this projector.

YUVꢀ

See YPbPr.

Zoomꢀ

The adjustment of image size by means of a zoom lens.
