Solutions When the Image Contains Noise or Static

If the projected image contains 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 in the projector's Signal menu to make sure they match the video source.

  • If available for your video source, adjust the Deinterlacing and Noise Reduction settings in the projector's Image menu.

    Image > Image Enhancement > Noise Reduction

    Image > Image Enhancement > Deinterlacing

  • Select Auto as the Resolution setting in the projector's Signal menu. (PowerLite 994F)

  • Select a computer video resolution and refresh rate that are compatible with the projector.

  • If you are projecting from a computer using a VGA computer cable, adjust the Tracking and Sync. settings in the projector's Signal menu. (PowerLite 994F)

  • If you adjusted the image shape using the projector controls, try decreasing the Sharpness setting in the projector's Image menu to improve image quality.

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