Supported Video Display Formats Solutions When the Image is Fuzzy or Blurry 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. • 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, use a lower resolution or try to match the projector's native resolution.
