or an extension cable, the image quality may be reduced.

■ Keep your computer and video cables away from the power cord

as much as possible to prevent interference.

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 74).

with 480i signals, turn on the

Progressive setting on the Signal

menu (see page 74).

the

Sharpness setting in the Image menu (see page 72).

■ If you’re projecting from a computer, make sure its signal is

compatible with the projector. See page 145.

■ If you’re projecting from a computer, press the Auto button on

the remote control to reset the projector’s Tracking, Sync, and

Position settings.

correction required.
