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
• No longer than 10 feet (3 m) for VGA/computer cables or 24 feet (7.3 m) for HDMI cables
• Check the settings on the projector's Signal menu to make sure they match the video source. If
available for your video source, adjust the Progressive and Noise Reduction settings.
• Select a computer video resolution and refresh rate that are 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. If the problem remains, display a uniformly patterned image on the
screen and manually 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.
