Problems with the Image or Sound
◗ An image does not appear on the screen.
Check that the Power light is on and the lens cover is off. Also make
sure the cables are installed correctly, as described in Chapter 1.
The correct image source may not be selected. Press the Computer
button on the control panel or the Comp1, Video, or BNC button
on the remote control to choose another image source.
◗ Only part of the computer image is displayed.
If the computer’s output resolution setting is higher than 1024
× 768
on the PowerLite 7250 or 7350, or higher than 800
× 600 on the
PowerLite 5350, the image is resized. (See page 70 for information on
resizing.)
If the computer output is not compatible with this resizing, choose a
different display setting as follows.
Windows:
In Windows 3.x, use Windows Setup in the Main program group. In
Windows 95/98, right-click on the desktop, select Properties, click
the Settings tab, and use the dialog box to select the resolution you
want.
