contains a lot of fine detail, you may notice one or more vertical 
stripes or bands, or some of the characters may look heavy or 
blurred. Press the 
Auto button on the remote control. This resets 
the projector’s tracking and sync settings.
■If further adjustment is needed, you can fine-tune the Tracking 
and 
Sync settings manually using the Signal menu as described 
on page 57. 
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. Or try 
projecting black text on a white background.
2. Adjust the 
Tracking to eliminate vertical stripes. 
3. Adjust the 
Sync to increase the sharpness of the image.
The colors of the image are not right.
■Try selecting a different Color Mode. See page 54 for 
instructions.
■If you’re displaying video, adjust the Color Saturation and Tint 
settings on the Image menu. See page 54 for instructions.
■Adjust the Brightness and Contrast settings on the Image 
menu. See page 54.
■Try adjusting the Color Adjustment setting on the Image menu. 
See page 55.
■Make sure the input signal setting on the Signal menu matches 
the signal from the connected device. If the image is too purple 
and you’ve connected a computer or RGB video device to the 
Computer(Component Video) port, select Computer as the 
input source. If you’ve connected a component video device, 
select 
Component Video. If you’re projecting from a composite 
video or S-Video source, make sure the correct 
Video Signal is 
selected on the Signal message. See page 56 for details.
