PowerLite 4750W WXGA 3LCD Projector
What should I do if I see static or noise in the image?
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
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
Progressive and Noise Reduction settings.
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 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.
If you connected through the
DisplayPort, change the DisplayPort EQ Setting in the Signal menu.
