The image contains static or noise.
■ If you’re using a computer cable longer than 6 feet, or an
extension cable, the image quality may be reduced. Use a
distribution amplifier for longer distances; you can purchase one
from Epson (see page 13).
■ Keep your computer and video cables away from the power cord
as much as possible to prevent interference.
■ 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 notebook
computer and the projector, turn off the notebook’s LCD display.
■ Make sure the correct input signal is selected in the Signal menu
(see page 67).
■ If still images are jittery when you are projecting from a video
source, turn on the
Progressive
setting in the Signal menu (see
page 66).
■ Select
Noise Reduction
in the Signal menu, then try selecting
NR1
or
NR2
.

There may be dirt or smears on the lens. Clean the lens as
