Support Projectors EB Series Epson BrightLink EB-770Fi

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, and directly in front of it.
    • Verify that the throw distance from the projector to your projection surface meets the specifications in the Installation Guide included with your mount.
    • Position the projector to minimize the need for keystone correction as much as possible.

      Note: Adjusting the image shape with the keystone setting or buttons can reduce the image quality.

    • Reset the keystone, Quick Corner, and Arc Correction settings to their factory defaults, and refocus the image.
    • Adjust the Sharpness setting to improve image quality.
    • If you are projecting from a computer using a VGA cable, 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, set the computer's output resolution to match the projector's native resolution.
