Solving Problems 75

■ 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 49).

The image is blurry.

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

described on page 60.

■ Adjust the focus using the focus ring (see page 21).

■ Make sure the lens is not fogged by condensation. You may need

to wait before using the projector after moving it from a cold

environment to a warm environment.

■ Adjust the Sharpness setting on the Image menu (see page 47).

When you change video settings, you should be able to see the

effect on the screen immediately. If you’re projecting from a

computer, you may also need to adjust the tracking and sync as

described in the next section. If you don’t like the new settings,

you can always select

Reset to return to the factory default

settings.

You see vertical bands or the image still looks blurry after

trying the solutions in the previous section.

■ If you’re projecting from a computer and displaying an image that

contains a lot of fine detail, you may notice vertical bands or some

of the characters may look heavy or blurred. Press the

Auto

button on the remote control to reset the projector’s tracking and

sync settings.

■ If further adjustment is needed, you can fine-tune the Tracking

and

Sync settings manually using the Signal menu, as described

on page 49.

1. Fill the screen with an image containing fine detail, such as a

pattern to appear as your desktop background, or try

projecting black text on a white background.
