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.
• 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.
• 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.
• Turn off any keystone correction and disable the
Quick Corner
setting.
