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 projection window.
Note: To avoid condensation on the projection window 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
your projector's online Installation Guide .
• Position the projector so the keystone adjustment angle is not so wide that it distorts the image.
• Adjust the Sharpness setting to improve image quality.
