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

• If the projected image is fuzzy or blurry, try the following solutions:

  • 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.
  • Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
  • When using the Screen Fit feature (PowerLite 1781W/1785W/1795F), 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 remain, display a uniformly patterned image on the screen and manually adjust the Tracking and Sync settings.
  • If you are projecting from a computer, try using a lower resolution or try to match the projector's native resolution.
