You can use the remote control (or the projector’s control panel) to 
access the menus and change settings. Follow these steps: 
1. To display the menu screen, press the

Adjusting the Image Quality
You can use the Video menu to adjust the brightness, sharpness, and 
contrast. If you’re projecting from a computer (but not through the 
DVI port), there are additional adjustments you can make (see 
page 65).
1. Press the 
Menu button on the remote control, then enter the 
Video menu. 
You see the Video menu screen (the actual settings may vary, 
depending on the selected input source).
2. Use the  pointer button to highlight the desired option, then 
adjust it as needed:
■Brightness 
Lightens or darkens the overall image.
■Contrast
Adjusts the difference between light and dark areas. If you’re 
projecting from a computer, select 
Auto to let the projector 
adjust the contrast automatically; or select 
Manual and then 
press 
Enter to adjust the setting yourself. 
■Sharpness
Adjusts the sharpness of the image.
note
The Brightness setting 
changes the opacity of the 
projector’s LCD panels. 
You can also adjust the 
brightness of the lamp itself. 
Select 
Brightness Control 
in the Advanced2 menu, 
then choose 
High or Low 
(the default setting is 
High). 
Selecting the low brightness 
setting extends the life of the 
lamp (see page 94).

Adjusting Computer Images
When you’re projecting an analog RGB computer image, there are 
several additional settings you can use to adjust the image. 
■Auto button
If your computer image doesn’t look correct, 
press the 
Auto button on the remote control 
(or the 
Auto/Enter button on the projector). 
This automatically resets the projector’s 
tracking, sync, resolution, and position 
settings. 
If further adjustment is needed, you can change 
these settings manually as described below.
■Tracking and Sync (in the Video menu)
If your image contains a lot of fine detail (such as text), you may 
notice one or more vertical stripes or bands, or some of the details 
may look heavy or blurred. You can adjust the 
Tracking and 
Sync settings manually: 
1. Fill the screen with an image containing fine detail when 
making these adjustments. For example, in Windows you can 
select a pattern to appear as your desktop background. If this 
option isn’t available, try projecting black text on a white 
background.
2. Press the 
Menu button on the remote control, then enter the 
Video menu. 
3. Adjust the 
Tracking to eliminate vertical stripes by pressing 
the left or right side of the  pointer button. 
note
These settings do not pertain 
to digital RGB images 
transmitted through the 
DVI port.Auto button 
						

							66Fine-tuning the Projector4. Adjust the 
Sync setting to reduce blurriness by pressing the 
left or right side of the  pointer button. (Be sure to adjust 
the tracking first for best results.)
■Resolution (in the Video menu)
If your image is distorted (compressed, stretched, partially cut off, 
or doesn’t completely fill the display area), the projector’s 
resolution setting may not match that of your computer. Select 
Auto to let the projector adjust the resolution automatically; or 
select 
Manual and then press Enter to adjust the setting yourself.
■Position (in the Video menu)
If the image is slightly cut off on one or more sides, it may not be 
centered exactly. You can use this setting to center it. 
■Preset (in the Video menu)
Once you’ve fine-tuned the settings in the Video menu for the 
computer you’re using, you can save them as a group, using of one 
of the ten 
Preset settings: 
1. From the Video menu, select 
Preset and press Enter.
2. Select a number (1 to 10).
3. Press 
Enter, then select Yes to overwrite.
4. Press 
ESC to exit the menu system.
The next time you use the same computer, simply press the 
Preset button on the remote control to recall your saved settings. 
(Press the 
Preset button repeatedly to select the number 
corresponding to the Preset setting you want to use.)

Adjusting the Image Size, Shape, and 
Position
Whether you’re projecting from a computer or video player, you can 
use these settings to adjust the size, shape, and position of the image.
■Resize button
Adjusts how an image fits into the display area. 
For computer images, resizing is normally unnecessary, since the 
projector automatically resizes the image to make the best use of 
the display area. If you press the 
Resize button on the remote 
control, the projector displays the image at the output resolution 
of the computer (which make the image larger or smaller, 
depending on its resolution). If the resolution of the image is the 
same as the projector’s (1024 
× 768), pressing Resize has no 
effect. 
For video images, pressing resize switches the aspect ratio between 
4:3 and 16:9. This lets you play certain digital video images or 
movies recorded on certain DVDs in 16:9 widescreen format. 
■Keystone (in the Setting menu)
Squares up the shape of the image after the projector has been 
tilted upward or angled to one side (see page 40). If you notice 
lines or edges looking jagged after adjusting the shape, decrease 
the Sharpness setting (see page 64). 
■Position (in the Video menu)
If the image is slightly cut off on one or more sides, it may not be 
centered exactly. You can use this setting to center it. 
note
If your computer image is 
stretched, compressed, or 
doesn’t fit correctly on the 
screen, you should try 
adjusting the Resolution 
setting first (see page 66). 
						

							68Fine-tuning the Projector
Adjusting the Color 
The projector provides several ways for you to adjust the color:
■Color Mode button (also in the Video menu) 
Lets you quickly adjust the color and brightness for various 
environments. Use either the remote control or the 
Color Mode 
setting in the Video menu. Select 
sRGB for standard computer 
displays (the default when projecting from a computer with 
analog video), or select one of the other color settings. You can 
save a different setting for each computer and/or video source. 
■Color (in the Video menu)
Adjusts the color intensity, from black-and-white to full color 
(not available for adjusting computer images).
■Tint (in the Video menu)
Adjusts the balance of magenta to green (not available for 
adjusting computer images).
■Color Adjustment (in the Advanced1 menu)
Adjusts the color temperature. Select Color Temp. to set a 
temperature between 5000 and 10000 °K. Or select 
RGB to 
adjust individual red, green, and blue values, as shown. (Not 
available if 
sRGB is selected as the Color Mode setting.)
■Black Level (in the Advanced1 menu)
Adjusts the brightness of dark shades without affecting the 
brightness of light shades. 
■White Level (in the Advanced1 menu) 
Adjusts the brightness of light shades without affecting the 
brightness of dark shades.

certain ports, turn on or off sleep mode, adjust the network settings, 
change the language, and customize several other features.
Image Setup Options
