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
 
- 
No longer
than 10 feet (3 m)
 
 
- 
Check the
settings on the projector's Signal menu to make sure they match the
video source.
 
- 
Select a
computer video resolution and refresh rate that are compatible with
the projector.
 
- 
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.
