Verify that the Desktop area is set to 800x600 or less, pref-
erably 640x480.
Also check the following:
•
Does your computer have a compatible graphics board? The
projectors aren’t CGA or EGA compatible.
•
Is your computer’s graphics board turned on? This is especially
true for laptop computers. See “Portable and Laptop Activa-
tion Chart” on page 55.
Problem: Image is too wide or narrow for screen
•
You might need to manually adjust the tracking to reduce or
enlarge the projected image. Refer to “Manual Tracking” on
page 38.
•
Adjust the resolution of your monitor if it’s greater than
800x600 for the 610 or 1024x768 for the 620. Only these resolu-
tions at 60 Hz or less display on the projector.
•
Make sure that your computer has a compatible graphics
board. The projector is not compatible with CGA, EGA, or
1280x1024 graphics modes.
Problem: Image is out of focus
•
Turn the projection lens to focus the image.
•
Make sure the projection screen is at least 5 feet from the pro-
jector.
•
Check the projection lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
•
The rear projection mode is probably set. Switch back to for-
ward projection from the Controls menu. The image should
immediately return to forward projection. See “Rear Projec-
tion” on page 40.
Problem: Image and menus are upside down
•
Ceiling mode is probably set. Turn off the mode from the Con-
trols menu. The image should immediately return to forward
projection. See “Ceiling” on page 39.
