Part of my image is blurred or out of focus. What should I do?

• Try the following:
  • Adjust the image focus.
  • Clean the projector lens.
    
    Note: To avoid condensation on the lens after bringing the projector in from a cold environment, let the projector warm up to room temperature before using it.
  • Position the projector close enough to the screen, and directly in front of it.
  • Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
  • When using the Screen Fit feature (PowerLite 1775W), position the projector at a compatible distance from the screen or adjust the image shape manually.
  • Turn on automatic keystone adjustment in the projector's menus.
  • Adjust the Sharpness setting to improve image quality.
  • If you are projecting from a computer, press the Auto button on the remote control to automatically adjust the tracking and sync. If any bands or overall blurriness remains, display a uniformly patterned image on the screen and manually adjust the Tracking and Sync settings.
