Vertical bands, static, or noise appear in the image. What should I do?

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 Noise Reduction setting.
• 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 connected an extension power cable, try projecting without it to see if it caused interference in the signal.
