I see dark vertical bands when projecting from a computer. What should I do?

• The Tracking and/or Sync settings may need to be adjusted. Press the Enter/Auto button on the remote control to reset 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 on the projector.
  1. Fill the screen with an image containing fine detail, such as a pattern to appear as your desktop background, or try projecting black text on a white background.
  2. Adjust the Tracking to eliminate vertical bands.
     
  3. 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.
