Q:
I see dark vertical bands in a projected computer image. What should I do?
A:
If you’re projecting from a computer and displaying an image that contains a lot of fine detail, you may notice vertical bands or some of the characters may look heavy or blurred. Press the Auto button on the remote control to reset the projector’s tracking and sync settings. Also make sure the refresh rate for your monitor is set correctly in your computer’s display settings.

If further adjustment is needed, you can fine-tune the Tracking and Sync settings manually using the Signal menu on the projector.

  1. Fill the screen with an image containing fine detail, such as black text on a white background.


  2. Adjust the Tracking to eliminate vertical bands.

  4. Adjust the Sync setting to increase the image sharpness.

Note: You must be projecting an image for this button to have any effect. The Auto button works only with computer images projected through the VGA port.
