Adjusting the Image Quality
You can use the Video menu to adjust the brightness, sharpness, color, 
tint, and contrast. If you’re projecting from a computer (but not 
through the 
DVI port), there are additional adjustments you can make 
(see page 67).
Adjusting Images from Video Sources
1. Press the Menu button on the remote control, then select the 
Video menu. 
You see the Video menu screen. (The actual settings may vary, 
depending on the selected input source. The Video menu below is 
for a composite video or S-Video source.)
2. Use the  pointer button to highlight the desired option, then 
adjust it as needed:
■Position
If the image is slightly cut off on one or more sides, it may not 
be centered exactly. Use this setting to center it (not available 
for RGB video images).
■Brightness 
Lightens or darkens the overall image.
■Contrast
Adjusts the difference between light and dark areas.

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 118).

Adjusting Computer Images
You can also adjust brightness, contrast, and sharpness when you’re

control’s 
Auto button to 
automatically reset the 
projector’s tracking, sync, 
resolution, and position 
settings. See page 39 for 
details.

Before adjusting tracking or 
sync, fill the screen with an 
image containing fine 
detail. 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.

■Sync
Adjust this value if the image appears blurry or flickers.
■Brightness
Lightens or darkens the overall image.
■Contrast
Adjusts the difference between light and dark areas. Select 
Auto to let the projector adjust the contrast automatically, or 
select 
Manual to adjust the setting yourself. (Press Enter after 
you make the selection.)
■Sharpness
Adjusts the sharpness of the image.
■Resolution
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 
Manual to adjust the setting yourself. (Press 
Enter after you make the selection.)
■Preset
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 one of the ten 
Preset settings. 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 
setting you want to use.) 
						

							Fine-tuning the Projector69
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 makes 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 36). If you notice 
lines or edges looking jagged after adjusting the shape, decrease 
the Sharpness setting (see page 68). 
■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 (not available 
for digital RGB or RGB video images). 
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 68). 
						

							70Fine-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; you can save a different setting for 
each computer and/or video source. Select from these settings:
sRGB: To use the sRGB standard for computer displays (the 
default when projecting from a computer with analog video)
Dynamic: For presentations in bright rooms 
Presentation: For presentations in dark rooms
Theatre: For optimizing movie images with natural color (the 
default for video display)
Living Room: For optimizing video games
■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 or RGB video 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.)

Customizing Projector Features
You can use the menu system to change the video signal input at 
certain ports, turn sleep mode on or off, adjust the network settings, 
change the language, and customize several other features.
Image Setup Options
Use these settings to change how the projector processes incoming 
video signals. Several of these settings should normally be left at the 
factory default setting (except for the 
Computer and BNC Input 
settings). 
■Computer Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the 
Computer port:
Analog-RGB: For a computer connection
RGB-Video: For a video player that outputs an RGB video signal 
■BNC Input (in the Setting menu)
Select the setting for the type of equipment you’ve connected to 
the BNC ports: 
Analog-RGB: For a computer connection
RGB-Video: For a video player that outputs an RGB video signal
YCbCr: For a video player that outputs a component video signal
YPbPr: For a video player that outputs a component video signal
■Video Signal (in the Video menu)
Leave this setting at Auto unless you are using a 60-hertz PAL 
system (select 
PAL60). You can change this setting only if you’re 
displaying an image through the 
Video or S-Video port. 
■Progressive (in the Advanced1 menu)
This setting should normally be left at its default setting (Video 
or 
Film/Auto). Converts interlaced signals to progressive signals. 
When set to 
OFF, interlaced signals are processed without 
conversion (available for video signals only).
