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, 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.
  • Try a different cable.
  • Try turning off Frame Interpolation, or turn on Image Enhancement in the Image menu.
