Solutions When the Image Contains Noise or Static
If the projected image seems to contain electronic interference (noise) or static, try the following
solutions:
• Check the cables connecting your computer or video source to the projector. They should be:
• Separated from the power cord to prevent interference
• Securely connected at both ends
• Not connected to an extension cable
• Check the settings on the projector's Signal menu to make sure they match the video source.
• Select a computer video resolution that is compatible with the projector.
• If you are projecting from a computer, press the Auto button on the remote control to automatically
adjust the Tracking and Sync settings.
• If you adjusted the image shape using the projector controls, try decreasing the Sharpness setting to
improve image quality.
• If you connected an extension power cable, try projecting without it to see if it caused interference in
the signal.

Solutions When the Image is Fuzzy or Blurry
If the projected image is fuzzy or blurry, try the following solutions:
• Adjust the image focus.
• 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.
