Important Operating Considerations for Safety  
Place the projector in a horizontal position no greater than 15 degrees off axis.  
Locate the projector in a well-ventilated area without any obstructions to intake or  
exhaust vents.  
Do not place the projector on a tablecloth or other soft covering that may block the vents.  
Locate the projector at least 4' (1.2 m) away from any heating or cooling vents.  
Use only Knoll-approved ceiling mounts.  
Use only the power cord provided. A surge-protected power strip is recommended.  
Refer to this manual for proper startup and shutdown procedures.  
In the unlikely event of the lamp rupturing, discard any edible items placed in the  
surrounding area and thoroughly clean the area along all sides of the projector.  
Wash hands after cleaning the area and handling the ruptured lamp. This product has a  
lamp, which contains a very small amount of mercury. Dispose of it as required by local,  
state or federal ordinances and regulations. For more information see www.eiae.org.  
Follow these instructions to help ensure image quality and lamp life over the life of the projector.  
Failure to follow these instructions may affect the warranty. For complete details of the warranty,  
see the Warranty section at the end of this User's Guide.

See “Video connectors” on page 9 for details.  
The projector also provides the following connectors:  
• RS-232 for serial control (not included on the HD108)  
• 12-volt DC output (see below)  
12-volt DC output  
The 3.5mm mini-jack trigger provides a 12-volt, 0.25 amp DC output. It provides a constant output  
while the projector is on. It has numerous uses. For example, if you connect your projection  
screen to the 12-volt DC output with the cable that came with your screen, when you turn on the  
projector the screen will move down; when you turn the projector off, the screen will return to the  
storage position.

Setting up the Projector  
There are a number of factors to consider when determining where to set up the projector,  
including the size and shape of your screen, the location of your power outlets, and the distance  
between the projector and the rest of your equipment. But here are some general guidelines.  
NOTE: To ensure adequate cable access, do not place the  
projector within 6 inches (0.15 m) of a wall or other object.  
Position the projector on a flat surface (either on a table or ceiling mounted) at a right angle to the  
screen.  
The projector should be within 10 feet (3 m) of your power source and within 6 feet (1.8 m) of  
your video source(s), unless good quality extension cables or baluns are to be used.  
When installing the projector on the ceiling, refer to the installation guide that comes with the  
Ceiling Mount Kit for more information. Knoll recommends use of the mount shipped with the  
projector or the deluxe swivel Knoll CM26 ceiling mount. The addition of a CM20+6 extension bar  
lowers the projector 6” per bar as required. The CM25EX is an adjustable extender that can lower  
the projector 6.75” to 11” (17-28 cm). The ceiling mount kit may be sold separately.

Position the projector the desired distance from the screen.  
The distance from the lens of the projector to the screen, the zoom setting, and the video format  
determine the size of the projected image.  
Projector Positioning  
The projected image becomes larger as the distance between the unit and screen increases.  
The manual zoom allows the distance from the screen to be within a minimum and maximum  
range. See the chart on the next page for details. The example below defines the screen height,  
width, diagonal, offset, etc. Note the bottom of the image starts about below the lens center with a  
horizontally or flat mounted projector.

Please note the HD404 projectors are designed for use with 16:9 screens. They  
also have a built in scaler for use with 2.35:1 screens. To display images at the  
highest definition possible in 2.35:1 or cinemascope (most major movies are  
filmed in 2.35:1) an anamorphic lens is required. We recommend the Panamorph  
brand, which has fixed, movable and motorized anamorphic lens for use with the  
HDP404.  
Choosing the aspect ratio  
Aspect ratio is the ratio of the image width to  
image height. HDTV and most DVDs are 16:9,  
which is the default for this projector. When in  
4:3 mode the projector places black bars on  
both sides of the image. Native mode centers  
the image and turns off the internal scaler so  
that any resolution larger than the native  
projector resolution is cropped on the edges.  
Letterbox expands the image to fill the screen.  
What you plan to project will also help you  
choose between 4:3 and 16:9. For example,  
most TV shows are 4:3, while most movies are  
16:9. If you have a 16:9 screen, then you should  
select an aspect ratio of 16:9 for anamorphic  
movies and HDTV, and Native for 4:3 content. If  
you have a 4:3 screen you should still use 16:9  
for anamorphic movies or HDTV, but you also  
have the option of using 4:3, Native, or Natural  
Wide for 4:3 content. Keep in mind that  
anamorphic movies only appear correctly if the  
DVD player is set to output to a 16:9 television.  
Natural Wide stretches a 4:3 image to fill the  
entire 16:9 screen. The center two-thirds of the  
image is unchanged; the edges of the image are  
stretched.

The first step for connecting video is determining what type of output connectors your video  
Component RCA device has. If there is more than one output, select the one with the highest  
quality. The best quality ranking, with 1 being the highest, is:  
1. M1-DA/DVI or HDMI (both are digital inputs).  
With a M1-DA to HDMI adaptor the HDP410, HDP420 and HDP460 have two HDMI inputs.  
2. Component /SCART RGB video (RCAs)  
3. S-video  
4. Composite Video (RCA)  
If your device has a VGA connector, you can use the M1-DA/DVI connector for a high-quality  
image. Many PC game systems have VGA connectors.  
Connecting a video device  
You can connect video devices such as VCRs, DVD players, camcorders, digital cameras, video  
game consoles, HDTV receivers, and TV tuners to the projector. Connect the audio from your  
video device to your stereo system to get sound. You can connect the projector to most video  
devices that can output video.  
You cannot directly connect the coaxial cable that enters your house from a cable or  
satellite company; the signal must pass through a tuner first. Examples of tuners are digital  
cable boxes, VCRs, digital video recorders, and satellite TV boxes. Basically, any device that can  
change channels is considered a tuner.  
A composite video cable is provided with your projector so you can quickly and easily connect a  
video source to the projector and see the amazing image that is displayed. Once you have  
determined a more permanent location for your projector, we recommend purchasing higher  
quality cables in the proper length to get the best image from your particular video equipment.  
Composite (RCA) video connection  
Plug the composite video cable’s yellow connector into the video-out connector on the video  
device. Plug the other yellow connector into the yellow Composite connector on the projector.  
S-video connection  
If your video device uses a round, four-prong S-video connector, plug the S-video cable into the  
S-video connector on your video device and into the S-video connector on the projector.  
Component (RCA) connection  
If your device uses component connectors, plug a component video cable with red, green, and  
blue RCA connectors into the source device’s component connectors and the Component  
connectors on the projector.  
SCART RGB connection  
SCART (from Syndicat des Constructeurs d'Appareils Radiorécepteurs et Téléviseurs) is a  
French-originated standard and connector for connecting audio and video equipment to display  
devices. The video signal is separated into its primary components for brighter, more accurate  
colors and sharper detail. You must enable this connector in the Source Enable menu to use it,  
see page 20. You will also need a SCART to 4-RCA adapter to connect to your SCART device.

10  
Digital connections  
The M1-DA/DVI and HDMI (High-Definition Multimedia Interface) connectors are digital and yield  
the highest quality image. It is common for these signals to be encrypted with HDCP (high-band  
width digital-content protection). Your new projector ships standard with decryption codes so you  
can enjoy these high quality, all digital images.  
This projector uses the M1-DA connector, which has the following advantages:  
• allows connection to a digital DVI source  
• allows connection to a component source  
• allows connection to an analog computer source  
• carries a USB control signal, which allows you to easily update your projector’s software as  
enhancements become available  
• has output pins that can power accessories  
HDMI 1.3 connection  
HDMI is a standard, uncompressed, all-digital audio/video interface. HDMI provides an interface  
between sources, such as set-top boxes, DVD players, and receivers and your projector. Plug an  
HDMI cable into the video-out connector on the video device and into the HDMI connector on  
the projector. To display HDMI 1.3 with its deep color and 30-bit detail, a HDMI 1.3 source is  
needed. Please note the HDP410, HDP420 and HDP460 have no audio capabilities at all.  
DVI connection  
If your video device uses a DVI connector, plug the DVI end of an M1-DA cable into the video-out  
connector on the video device. This connector may be labeled “To Monitor” on the video device.  
Plug the M1-DA end of the cable into the M1-DA/DVI connector on the projector.  
Note that the projector has no audio capabilities, so audio signals transferred through HDMI  
will not be audible.  
Computer connections  
You can connect a computer’s VGA connector to the M1-DA/DVI input on the projector using an  
M1-A cable.  
RS-232 connections  
You can control the projector from an LCD control panel or computer by connecting an RS-232  
cable to the projector’s Serial control connector.  
Displaying an image  
Connect the power cord to the Power connector  
on the back of the projector and to your electrical outlet.

Sleep Timer  
The projector also has a sleep timer feature that automatically turns the projector off after four  
hours. See page 21.  
Turning off the projector  
Press the Power button on the remote or keypad to turn the projector off. The lamp turns off and  
the LED blinks green for one minute while the fans continue to run to cool the lamp. While the  
LED is blinking green, the projector does not accept any user input. Once the cooling process is  
complete, the LED lights solid green and you can turn the projector back on, if desired.  
NOTE: Once the projector has been turned off, you must wait for one minute before turning the  
projector on again. This allows the lamp to properly cool and extend the lamp life up to 3000  
hours). The LED light is solid green when the cooling process is complete.  
NOTE: The biggest cause of early lamp failure is not allowing the lamp to cool properly, either  
from power failures or disconnecting power to the projector before the fan can cool the lamp  
properly.  
Troubleshooting your setup  
If your image appears correctly on the screen, skip to the next section. If it does not, troubleshoot  
the setup. The LED on top of the projector indicates the state of the projector and can  
help you troubleshoot.  
The status indicator on the top of the projector can help you diagnose any problems the projector  
is experiencing.

Sharpness: (video sources only) changes the clarity  
of the edges of a video image. Select a sharpness setting.

Color Space: this option applies to computer and  
component video sources. It allows you to select a  
color space that has been specifically tuned for the  
input signal. When Auto is selected, the projector  
automatically determines the standard. To choose  
a different setting, turn off Auto, then choose RGB  
for computer sources, choose either REC709 or REC601  
for component video sources.  
Color space  
Color Temperature  
Color Temperature: changes the intensity of the colors.  
Select a value. Native means an uncorrected/unchanged  
color temperature. Other values change the white point  
of the colors. 6500K is generally used for film content  
and 9300K is used for TV video.  
Color Control  
Color Control: allows you to individually adjust the  
gain and offset of the red, green, and blue colors.  
These advanced controls have the same effect as  
contrast and brightness, but each controls a single color only.  
Video Standard: when it is set to Auto, the projector  
attempts to automatically pick the video standard based  
on the input signal it receives. (The video standard options  
may vary depending on your region of the world.) If the  
projector is unable to detect the correct standard, the  
colors may not look right or the image may appear “torn.”  
If this happens, manually select a video standard by  
selecting NTSC, PAL, or SECAM from the Video Standard  
menu.  
Video Standard  
Overscan: removes noise around the edges of the video  
image. Select Zoom to remove the outer 3 percent of the  
image and scale the image back up to its original  
size. Select Crop to remove the outer 3 percent of the  
image without rescaling the image.  
Overscan  
Noise Reduction: adjusts signal noise reduction.  
Choose Enable then adjust the level. The software  
determines the differences between successive image  
frames and averages the changes out to reduce the noise.  
Noise reduction  
Settings menu  
Sources: allows programming of source buttons,  
enables autosource, and enables the SCART RGB  
source. When Autosource is selected, the Source  
Enable feature indicates which sources the projector  
attempts to lock onto. You can use the Source Enable  
feature to eliminate certain sources from this  
search, which will speed the search. By default,  
the check boxes for all sources are checked except  
SCART RGB. Uncheck a source box to eliminate  
it from the search.

21  
When Autosource is not checked, the projector defaults to Component initially, then defaults to  
whatever the last active source was when the projector was powered down. To display another  
source, you must manually select one by pressing the Source button on the remote or keypad.  
This cycles through all the sources that are selected in the Source Enable menu.  
The Source 1, 2, and 3 menus in the Sources menu allow  
you to assign a source to the Source 1, 2, and 3 buttons  
on the remote. The Source 4 menu selection would  
apply to the Custom key if that option is chosen in the  
Custom key menu, see page 22.  
Sources  
Source Enable  
To use the SCART RGB source, you must first select  
it in the Source Enable menu (the projector cannot  
automatically detect this source). Enabling  
SCART will disable Component and Composite  
sources.  
System>OSD Offset: System>OSD Offset: allows you to adjust the  
position of the OSD. By default, the menus are postponed in the  
upper left hand corner of the displayed image and the messages are  
postponed in the lower left hand corner. Adjust the offset to move  
these items more to the right and middle of the display.  
Rear: reverses the image so you can project from behind a  
translucent screen.  
Ceiling: turns the image upside down for ceiling-mounted projection.  
Auto Ceiling: uses an internal sensor to automatically turn  
on ceiling mount mode if the projector is inverted.  
High Power: maximizes the light output of the lamp.  
Auto Power: when AutoPower is checked, the projector automatically goes into the startup state  
after the projector receives power. This allows control of ceiling mounted projectors with a wall  
power switch.  
Display Messages: displays status messages (such as “Searching”) in the lower-left corner of  
the screen.  
Translucent OSD: makes the menus translucent. This prevents the image from being completely  
covered by the menus while you are making image adjustments.  
Sleep Timer: automatically turns off the projector after 4 hours.  
Power Save: automatically turns the lamp off after no signals are detected for 20 minutes. After  
10 additional minutes with no signal, the projector powers down. If an active signal is received  
before the projector powers down, the image is displayed.  
Startup Logo: allows you to display a blank screen  
instead of the default screen at startup.  
.
Blank Screen: determines what color is displayed when  
you select Blank Screen in the Startup Logo menu  
and when no source is displayed.

22  
Language: allows you to select a language for the onscreen display.  
Custom key: allows you to assign a different function to the Custom  
key on the remote, allowing you to quickly and easily use the effect. Highlight an effect and  
press Select to choose a different one.  
Blank Screen: displays a solid blank image.  
Freeze: takes a snapshot of the projected image. If you’re watching video, the source video  
continues to run but the image is frozen.  
Source Info: the default effect. It opens a window with projector and source information.  
Service Info: opens the Service info window.  
Source 4: selects source 4 (by default, Source 4 is the Composite input). This gives you four  
direct source options on the remote. See page 20.  
Service: To use these features, highlight them and press  
Select.  
Factory Reset: restores all settings to their default.  
Reset Lamp Hours: resets the lamp hours used in the  
Service Info menu to zero. Do this only after changing the  
lamp.  
Test Pattern: displays a test pattern. To display test patterns, first you must assign Blank Screen  
to the Custom key (page 17), then click the Test pattern check box in the Service menu to turn  
the option on, exit the menus, then press the Custom button on the remote. To select the  
patterns, use the up/down arrows on the remote or keypad. To exit the test patterns press  
the Custom button.  
Blue Only: turns off the Red and Green  
portions of the input, allowing you to properly  
adjust the color balance with a SMPTE color  
bar pattern.  
HDMI DDC: turns off the EDID extension.  
Some graphic cards cannot recognize the  
projector’s EDID. Uncheck this box if you  
have trouble using HDMI or DVI sources.  
Service Info: provides information about the  
projector’s software, serial number and lamp.  
Source Info: provides information about the active source.  
Service Code: only used by authorized service personnel.

Maintenance  
Cleaning the lens  
1 Apply a non-abrasive camera lens cleaner to a  
soft, dry cloth.  
Avoid using an excessive amount of cleaner,  
and don’t apply the cleaner directly to the lens.  
Abrasive cleaners, solvents or other harsh  
chemicals might scratch the lens.  
2 Lightly wipe the cleaning cloth over the lens in a  
circular motion.  
Lamp hours used  
Replacing the projection lamp  
The lamp hour’s timer in the Service Infomenu counts the  
number of hours the lamp has been in use. Twenty hours  
before the lamp life expires a message appears on the  
screen at startup indicating that you should change the  
lamp. The LED on the top of the projector also blinks red  
twice to indicate that the lamp should be changed. Use only  
a replacement lamp with the same type and rating as the  
original lamp. Lamps can be purchased direct from Knoll or  
the dealer that sold the projector.  
wait 60 minutes  
turn off and unplug the projector  
1 Turn off the projector and unplug the power cord.  
If ceiling mounted, disconnect all cables and  
detach the projector from the ceiling mount.  
2 Wait 60 minutes to allow the projector to  
cool thoroughly.  
3. Turn the projector upside down on a  
soft cloth so that the lamp door is  
facing you. Remove the base or ceiling  
mount plate, if attached, by removing the three screws.  
4.Loosen the two captive screws on the lamp door and lift it off.  
5. Loosen the two captive screws that attach the lamp housing  
to the projector.  
6. Carefully remove the lamp housing. Dispose of the lamp in  
an environmentally proper way.  
WARNING:  
To avoid burns, allow the projector to cool for at least 60 minutes before you replace the lamp.  
Be extremely careful when removing the lamp housing. In the unlikely event that the bulb  
ruptures, small glass fragments may be generated.  
The lamp housing is designed to contain these fragments, but use caution when removing the  
lamp housing. Before replacing the lamp, clean the lamp compartment and dispose of cleaning  
materials. Make sure to wash your hands after lamp replacement. This product has a lamp, which  
contains a very small amount of mercury. Dispose of it as required by local, state or federal

backlight blinks twice when discrete mode is entered. The remote buttons are now remapped to  
new functions as listed below. To return to normal remote mode, press and hold the Custom  
button on the remote for 10 seconds. The remote also returns to normal mode automatically if no  
activity is detected for two minutes.

RS232 COMMAND FORMAT  
All commands consist of 3 alpha characters followed by a request, all enclosed in parentheses.  
The request can be a read request (indicated by a “?”) or a write request (indicated by 1 to 4  
ASCII digits).  
A read request format (AAA?) where  
(
starts the command  
denotes the command  
denotes the read request  
ends the command  
AAA  
?
)
A read command returns the range and the current setting, for example:  
Function  
Command  
Response  
Brightness  
Lamp hours  
(BRT?)  
(LMP?)  
(0-22,10)  
0-9999,421)  
A write request example: (AAA####) where  
(
starts the command  
denotes the command  
AAA  
#### denotes the value to be written (leading in zeros not necessary)  
ends the command  
)
Some commands have ranges, while others are absolute. If a number greater than the maximum  
range is received, it is automatically set to the maximum number for that function. If a command  
is received that is not understood, a “?” is returned. With absolute settings, “0” is off, 1-999 is on.  
The one exception is the Power command, where 0 is off and 1 is on.
