■ Adjust the Sharpness setting on the Video menu (see
Chapter 6). When you change video settings, you should
be able to see the effect on the screen immediately. If you’re

like the new settings, you can always select
Reset to return to
the factory default settings.

■ If you’re projecting from a computer and displaying an image that
contains a lot of fine detail, you may notice one or more vertical
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 Video menu as described in
Chapter 6.
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. Adjust the Tracking to eliminate vertical bands.
