Display Setup
Use the OSD buttons to set up the display:
1. Turn on the display with the POWER button.
2. The display will initially be set to properly display the native resolution for the LCD panel,
which is 1024 x 768 pixels. If your computer outputs a video signal at another resolution,
further adjustment than described in this section may be required. Contact Preh Technical
Support at [email protected] if assistance is required.
3. Press the ENTER button on the OSD controls. A pop-up window on the display should
appear with the message “Auto Adjusting Please Wait.”
Color Adjustment
Adjusts preset color temperature of the image. Available choices are
9300, 7500, 6500, and 5500° Kelvin (K). A User mode allows custom
setup of each color component of the image-Red, Green and Blue.
Default setup for this parameter is 6500° K. Do not adjust color
temperature unless you have a specific need to do so.
Audio Adjustment
Volume
Adjusts the loudspeaker volume.
4. Inspect the top, bottom, left and right edges of a typical application to make sure you can
see the entire image on the display without scrolling. If so, you are finished with the basic setup
of the display.
Mute ON/OFF
Auto Dim
Mute ON turns off the audio function. Mute OFF restores the audio.
Display Resolution
Auto DIM
Turns the Auto-Sensing Brightness Adjustment circuit ON or OFF.
If your application requires use of the display at another resolution than 1024 x 768, such
as 800 x 600, you may achieve satisfactory operation by using the Auto Adjust procedure
described above, or you may need to use the individual controls in the OSD to properly adjust
the display. Access the OSD main menu and use the Video Adjustment functions (see table on
next page) to resize, move, or adjust the quality of the displayed image.
Dimming Range
Menu shows sensed light level, and brightness setting as a percent
age of full scale (same setting as Brightness in Contrast and Brightness
menu when Auto DIM is OFF). With Auto DIM ON, brightness is now
controlled by the light sensor located at top center of the front bezel.
See additional discussion of the Auto-Sensing Brightness Adjustment.

A Dimming Range setting of 100 means that the image brightness will be reduced to its
minimum in total darkness conditions.
A Dimming Range setting of 0 means that the image brightness will not be reduced at all
under total darkness conditions.
Power/OSD Lock/Unlock Note:
There is no menu graphic for this feature. The Power/OSD lockout menu is separate from the
main OSD.
1. Access this feature by first pressing the MENU button to access the main OSD.

Touchscreen Features and Use
3. While continuing to hold the MENU button down, momentarily press the POWER button.
The POWER/OSD lockout menu will appear.
Your Preh MCI Touch series touch display is equipped with a resistive touchscreen. Features
of a resistive touchscreen that are important for your use are:
4. Press the ENTER button to alternately select OSD or POWER, and use the UP and DOWN
buttons to toggle your selection between UNLOCK (the default) and LOCK.
•
•
Composition: The touchscreen is made of a thin (about 1/8”) sheet of glass overlaid with
a layer of plastic. The resulting composite is placed in front of the LCD panel in your Preh
MCI Touch Monitor.
OSD LOCK defeats all normal access to the OSD, including the Direct Access shortcuts to
Brightness, Audio, and Video Auto Adjust. To access the OSD when in OSD LOCK, press and
hold MENU, and while holding MENU down, momentarily press POWER.
Activation: The touchscreen can be activated by anything that applies a force of about 1
ounce over a normal fingertip-sized area. Objects with smaller contact areas such as a
credit card, pen, pencil tip or pencil eraser will activate the touchscreen with even less
force. So, in normal circumstances, a very light touch is all that is required to navigate your
application with the touchscreen.
POWER LOCK defeats the operation of the POWER button. This feature, in addition to
preventing casual vandalism of the system, allows the MCI Touch Monitor to power up properly
when the system or MCI Touch Monitor is powered from an outlet strip or remote master
switch, or when the monitor is installed in a kiosk or other location where the power button is
inaccessible.
•
•
Use and Abuse: The touchscreen plastic layer has a hard front surface coating on it, and
will withstand years of use with fingers, fingernails and other relatively large radius styli.
However, hard objects with sharp edges can easily damage the touchscreen. Avoid the
use of ball-point pen barrels with the tip retracted, microball pens, keys, rings, coins and
metal tableware.
OSD buttons
UP, DOWN and ENTER will scroll through available choices when held down continuously.
The Auto-Sensing Brightness Adjustment feature is intended to be used in situations where
the ambient lighting can change significantly over time.
Cleaning: The touchscreen may be cleaned with common glass cleaners, but do not use
cleaners with abrasives-Comet, BonAmi, etc. The best procedure for cleaning the screen
is to apply your cleaner to a soft cloth or paper towel, and wipe the touchscreen until
contamination is removed. Applying cleaner to the cloth rather than spraying it directly
on the screen will minimize the amount of overspray that may collect at the bottom of the
screen.
The brightness of the image tracks ambient brightness and dims the display as the ambient
light decreases, making the image less obtrusive under reduced lighting conditions where high
image brightness is not necessary for good viewability.
To use Auto-Sensing Brightness Adjustment:
1. Turn AutoDIM OFF with the Auto DIM OSD menu.
2. Set Brightness to desired value in brightest expected ambient light.
3. Turn AutoDIM ON.
4. Set the Dimming Range to desired value. (See discussion below.)
5. Close AutoDIM menu.
•
Application Use: One characteristic of the resistive touchscreen technology is that it
averages multiple touches. So, If you touch the screen with two fingers at the same time,
on opposite sides of the display, the reported location to the application will be in the
middle of the screen! Consider this in navigation of your application.
Touchscreen and Peripheral Drivers
If the brightest ambient light is 150 or above as reported by the Auto DIM OSD menu (units
are approximately in Lux, a common measure of illuminance, or lighting of surfaces by light
sources), the brightness will not change when the Auto Dim feature is turned ON.
Drivers for different operating systems have been supplied on a CDROM that accompanied
your MCI Touch Monitor. If you cannot find the disk or need additional copies of the software,
contact Preh at [email protected] (Americas only) or [email protected]
Note: Drivers for the MCI 15T’ MSR and Line Display modules
However, when the ambient lighting is less than 150, the display will immediately dim in
response to the setting of the Auto Dim range and the ambient light:
Drivers for the MCI 15T’ MSR and Line Display modules might not be included in your
installation CD
•
Dimming Range is a measure of how much the display will dim when ambient light is
reduced.
Please download latest drivers from our support area at
•
Dimming only occurs in the ambient light range of 0-150 (Lux) as measured by the
automatic light sensor. If the ambient light is brighter than 150, no dimming will occur until
the light level drops below 150, and then will drop proportionally to the measured light
level.

AMTFT: Acronym for Active Matrix Thin Film Transistor. This is the type of liquid crystal display
panel used in essentially all computer flat panel displays today.
Temperature
0°C to 40°C
Calibrate: For touchscreens, “calibrate” is the common term for the process that is really
“video alignment.” A touchscreen and its controller have a coordinate system that are usually
not identical to the coordinate system of the video display of the host computer. By displaying
reference points on the MCI Touch Monitor (through the calibration program) and touching
those reference points, the MCI Touch Monitor coordinate system is scaled to that of the
computer.

Color temperature: Color temperature is a simplified way to characterize the spectral
properties of a light source, and is the temperature you would heat a theoretical “black body”
source to radiate light of the same visual color. For example, “low” color temperature, like
3200°K, implies warmer (more yellow/red) light, while “high” color temperature, like 9300°K,
implies a cooler (more blue) light. Daylight has the 3200°K temperature mentioned near dawn
and evening, and a higher one during the day. The standard unit for color temperature is the
Kelvin (K).

Contrast Ratio: The ratio of the luminance of the display of a full white image to a full black
image. This parameter is useful in determining the relative sharpness of two displays-a higher
contrast ratio usually implies a sharper image, especially when text is displayed.

& swivel) Movement (Only MCI 15T
C2RT4 and MCI 15T C1RT4)
Emulation: As used in display technology, emulation mode means an image displayed at a
non-native resolution. For your Preh MCI Touch Monitor and other 15” monitors, the common
emulation modes are 800 x 600 and 640 x 480. In emulation modes, a monitor cannot perfectly
display the image sent from the computer when the monitor pixel to image pixel ratio is not an
integral multiple.

Kelvin: The scale of temperature measurement that begins at absolute zero. The increment of
temperature that one Kelvin represents is the same as that of the Celsius scale, but the scale
starts at -273.16°C. Thus 293°K is about 20°C or 68°F.

ALL OTHER WARRANTIES, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO,
IMPLIED WARRANTIES OF
Lux: The standard unit for illuminance is lux (lx) which is lumens per square meter (lm/m2).
1 lux=10.764 footcandle. Common room lighting is 100-1000 lux.
MSR: Acronym for Magnetic Stripe Reader. A device that reads information encoded in the
magnetic stripes on the back of a credit card, etc. The process is essentially identical to the
operation of a cassette tape player.
Native resolution: The resolution of a digital flat panel display that actually describes how
many pixels are in each row and column of the display, and which is the resolution that the
display is optimized for. Your 15” Preh MCI Touch Monitor has a native resolution of 1024 x
768, which means that the LCD panel has 1024 pixels on each row, and has 768 rows. Each
element of video information received from the computer/display electronics is assigned to and
displayed by a specific location on the display panel-a pixel. At resolutions other than native
(see emulation) there is not a one-to-one correspondence between the video information
elements and the available pixels on the display. The display electronics must compensate for
this and cannot do a perfect conversion, thus emulation modes never look as good as images
displayed at the native resolution.
Nit: The standard unit of luminance is the candela per square meter (cd/m2), or Nit.
Pixel: Abbreviation for “picture element.” In an electronic display, the smallest complete
element of the picture that contains all possible colors and proper brightness. In your Preh MCI
Touch Monitor, one pixel of the LCD panel is a square “window,” with an area of about 0.3 x
0.3mm, containing three smaller windows that pass red, green or blue light at the appropriate
brightness in response to the video signal from the computer.
Polarizer: A thin glass or plastic sheet that filters out light rays of all but a specific orientation.
Light passing through such a sheet is thus polarized.
POS: Acronym for Point Of Sale.
Serial: A data transmission method where each bit (a “1” or “0”) of data is passed sequentially
(or serially) over a single data path (a wire…). The most common standard for this method
is called RS232. This is a very common method of interfacing peripheral equipment to older
computers. Today this method is increasingly replaced by another method called USB (see
below).
USB:Acronym for Universal Serial Bus.Acommon method for interfacing peripheral equipment
to computers. It has the advantages over other serial data transmission standards of higher
speeds and the ability to connect many devices to the same port on a computer.
VESA: Acronym for Video Electronics Standards Association. An industry trade group that
promotes interoperability standards within the video and computer industry.The VESAmounting
pattern (75mm) for displays is used by your Preh MCI Touch Monitor on the base and chassis,
allowing the monitor to be quickly attached to standard swing arms and mounting plates.
