If the image is not square, adjust the keystone using the buttons on the keypad. Press the upper Keystone 
button to reduce the width of the upper portion of the image, and press the lower Keystone button to reduce 
the width of the lower portion. 
 
The Contrast, Brightness, Color, and Tint are factory calibrated to D65 colors, but you can adjust these 
settings in the Picture menu if necessary.  
 
 
 
 
Connecting to a computer 
 
Connect either a VESA cable or M1 cable into the appropriate connector on the projector. Connect the other 
end to the video port on your computer. If you are using a desktop computer, you first need to disconnect 
the monitor cable from the computer’s video port.  
 
You can control the projector from an LCD control panel or computer by connecting an RS-232 cable to the 
projector’s Serial connector. Specific RS-232 commands can be found in the Appendix

Shutting down the projector 
Power Save 
The projector has a Power Save feature in the System menu that 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. You must press the 
Power button to display an image after 30 minutes have passed.  
 
Turning off the projector 
To turn off the projector, press the Power button. The lamp turns off and the LED blinks green for about one 
minute while the fans continue to run to cool the lamp. When the lamp has cooled, the LED lights green and 
the fans stop. Unplug the power cable to completely power off the projector. 
 
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’s keypad indicates the state of the projector and can 
help you troubleshoot.

remote’s back, aligning the + and - ends of the batteries, sliding them into place, and then replacing the

Optimizing video images 
After the video device is connected properly and the image is on the screen, you can optimize the image 
using the onscreen menus. 
Change the Aspect ratio. Aspect ratio is the ratio of the image width to image height. TV screens are usually 
1.33:1, also known as 4:3. HDTV and most DVDs are 1.78:1, or 16:9. Choose the option that best fits 
your input source in the menus, or press the Resize button on the remote to cycle through the options.  
Adjust the Keystone, Contrast, Brightness, Color, or Tint in the Picture menu.  
Select a different Color Temperature or use the Color Control to adjust the gain and offset of the red, green, 
and blue color. 
Select a specific Color Space or Gamma. 
Select a different Video Standard. Auto tries to determine the standard of the incoming video. Select a 
different standard if necessary. 
Turn overscan on to remove noise around the video image.  
Fine tune component inputs using the TrueLife™ adjustments. 
Choose High Power to maximize the light output. 
Make sure your DVD player is set for a 16:9 television. See your DVD player’s user’s guide for instructions. 
Customizing the projector 
You can customize the projector for your specific setup and needs. 
For rear projection, turn Rear mode on in the Settings>System menu. 
For ceiling mounted projection, turn Ceiling mode on in the Settings>System menu.  
Turn the projector’s display messages and power-on chime on and off. 
Turn on power saving features.  
Specify blank screen colors and startup logos. Make the menus translucent. 
Specify the menu language. 
Using the menus 
To open the menus, press the menu button on the 
keypad or remote. (The menus automatically close 
after 60 seconds if no buttons are pressed.) The Main 
menu appears. Use the arrow buttons to move up and 
down to highlight the desired submenu, then press the 
Select button.  
To change a menu setting, highlight it, press Select, 
then use the up and down arrow buttons to adjust the 
value, select an option using radio buttons, or turn the feature on or off using check boxes. Press Select to 
confirm your changes. Use the arrows to navigate to another setting. When your adjustments are complete, 
navigate to Exit, then press Select to go to the previous menu; press the Menu button at any time to close 
the menus.  
Dots appear before the menu name. The number of dots 
indicate the menu’s level, ranging from one (the Main 
menu) to four (the most nested menus).

The menus are grouped by usage: 
The Picture menu provides image adjustments. 
The Settings menu provides set-up type adjustments that are not changed often. 
The About menu provides a read-
only display of information about 
the projector and source.  
Certain menu items may be hidden 
until a particular source is 
connected. For example, Tint is 
only available for NTSC video 
sources and will be hidden when 
other sources are active. Other 
menu items may be grayed out when they are not available. For example, Brightness is grayed out until an 
image is active. 
 
Picture menu 
To adjust the following five settings, highlight the setting, 
press Select, use the up and down arrows to adjust the 
values, then press select to confirm the changes. 
 
Keystone: adjusts the image vertically and makes a 
squarer image. You can also adjust keystone from the 
keypad. 
 
 
 
Contrast: controls the degree of difference 
between the lightest and darkest parts of the picture and changes the amount of black and white in the 
image. 
Brightness: changes the intensity of the image. You can also adjust brightness from the keypad. 
Color: (video sources only) adjusts a video image from black and white to fully saturated color. 
Tint: (NTSC video sources only) adjusts the red-green color balance in the image. 
Aspect Ratio: Aspect ratio is the ratio of the image width to 
image height. TV screens are usually 1.33:1, also known as 
4:3. HDTV and most DVDs are 1.78:1, or 16:9. You can 
choose Native, 4:3, 16:9, Letterbox, or Natural Wide. The 
default is 16:9. The goal is to show the most detail on the 
screen while preserving the ratio of width to height. The native 
resolution of the projector is 1280x720. Use Native, 4:3 or 
Naural Wide for 4:3 input sources; use Native, 16:9 or 
Letterbox for 16:9 input. Pressing the Resize button on the 
remote cycles through these options.

Native: this mode bypasses the internal scaler, displaying the image with no resizing.  
Since the native resolution is 1280x720 and 4x3 video images are approximately 
640x480, 4x3 images will always be smaller than the display and will be centered in the 
display.  Computer images 1024x768 or smaller will also be centered in the display.  If a 
16x9 video source or a 1280x1024 or larger computer source is viewed, it will display up 
to 1280 pixels and 720 lines from the center of the input. 
 
16:9: the default is 16:9, which preserves the 16:9 aspect ratio and is designed to be 
used with content that is Enhanced for Widescreen TVs.  
 
 
 
4:3: resizes the image from its original version to fit a standard 4:3 aspect ratio screen. If 
you have a 4:3 source on a 16:9 screen, the image is placed in a 16:9 space, so black 
bars appear at the sides of the image. 
 
 
 
Letterbox: preserves the 16:9 aspect ratio. If you have a 16:9 source and screen, the 
image fills the screen. If your source is letterboxed, the image expanded to fill the 
screen. 
 
 
 
 
 
 
  
						

							 
20
 
 
Natural Wide: this mode 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.  
 
 
 
Presets: This allows you to customize settings and save the settings to be restored later. To restore the 
factory default settings, choose Factory Reset in the Settings>Service menu.  
 
 
To set a preset for the current source, adjust the image, select Save Settings in the Presets menu, then 
choose Save User 1, 2, or 3. You can recall these settings in the future by selecting the appropriate user 
presets.
