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:

• 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.
• Adjust the
