What should I do if I see static or noise in the image?
Check the following:
If you’re using a computer cable longer than 6 feet (1.8 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.
If you’re projecting from a composite video source, check the Video Signal setting in the Signal menu. In most cases, leave it set to Auto. If you’re using a 60-Hz PAL video source, change this setting to PAL60. See Adjusting Signal Settings.
If you’ve used the Quick Corner or Keystone adjustment, you may need to decrease the Sharpness setting in the Image menu. See Adjusting the Image for details.
Make sure the cables are securely connected at both ends.
