Q:
What should I do if I see static or noise in the image?
A:
Check the following:

  • If you’re using a computer cable longer than 6 feet (2 meters), or an extension cable, the image quality may be reduced.


  • Keep your computer and video cables separated from the power cord as much as possible to prevent interference.


  • If you’re using an extension cable, you may pick up interference if the cable is not adequately shielded. You may need to use a signal amplifier for longer cables.


  • The video signal may be split between the computer and the projector. If you notice a decline in the projected image quality when the image is displayed simultaneously on your laptop computer and the projector, turn off the laptop’s LCD display.


  • Make sure the correct input signal is selected in the Settings menu. See Customizing Projector Features for details.


  • If you’re projecting from a composite or S-Video source, check the Video Signal setting in the Settings menu. In most cases, leave it set to Auto. See Customizing Projector Features.


  • If you’re viewing video through the S-Video or composite inputs, and you notice flickering or horizontal lines, adjust the Progressive setting for the type of input you are displaying. See Sharpness and Picture Quality Settings.


  • Make sure the cables are securely connected at both ends.


  • Select the correct resolution. See Compatible Video Formats.


  • If you’re projecting from a computer, press the Enter button on the remote control or the Enter button on the projector to adjust tracking and sync automatically. If that doesn’t work, try adjusting the Sync and Tracking settings in the Signal menu. See Adjustments for Computer Images.


  • If you’re projecting from a DVD player, VCR, or other video source, make sure the correct output signal is selected on the device.
