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
• Make sure you selected the correct Signal Format or EDID settings in the projector's Signal I/O
menu, if available for your image source.
• Adjust the Noise Reduction, MPEG Noise Reduction, and Deinterlacing settings in the projector's
Image menu.
• If available for your video source, select Auto as the Resolution setting in the Image menu.
• Select a computer video resolution and refresh rate that are compatible with the projector.
• 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 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.
