Maintenance & Troubleshooting
You might need to turn everything off and power up the
equipment again in the proper order. Refer to your com-
puter’s documentation to determine the correct order.
Make sure your laptop’s external video port is turned on. See
the “Portable and Laptop Activation Chart” on page 52 or
your computer’s manual for details.
Make sure your computer’s video board is installed and con-
figured correctly.
Make sure your computer has a compatible video board. The
projector isn’t CGA, EGA or SXGA compatible.
If you’re using Windows 98:
1
Open “My Computer” icon, the Control Panel folder and
then the Display icon.
2
Click the Settings tab.
3
Verify that the Desktop area is set to 1280x1024 or less.
Problem: Image is too wide or narrow for screen
Adjust the zoom or projector placement.
Adjust the resolution of your video card if it’s greater than
1280x1024.
Problem: Image is out of focus
Turn the projection lens to focus the image.
Make sure the projection screen is at least 3.3 feet (1 m) from
the projector.
Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
Rear projection mode is probably turned on. Turn Rear Projec-
tion off in the Controls menu. The image should immediately
return to forward projection. See “Rear Projection” on
page 36.
