Problem: Projected colors don’t match the computer or video 
player’s colors

Adjust the brightness, tint and/or contrast from the Display 

menu. Just as there are differences in the displays of different 
monitors, there are often differences between the computer 
image and the projected image. See “Brightness” on page 17, 
“Tint” on page 17 and “Contrast” on page 17. 

Problem: Lamp seems to be getting dimmer

The lamp begins to lose brightness when it has been in use for 

a long time. Replace the lamp as described in “Replacing the 
Projection Lamp” on page 25.

Problem: Lamp shuts off

A minor power surge may cause the lamp to shut off. Turn the 

projector off, wait at least a minute, then turn it back on.

Before calling your dealer or In Focus Technical Support for assis-
tance, please have the following information available:

the projector’s serial number (located on the bottom label)

the resolution of your computer.

Call In Focus Technical Support at 

1-800-799-9911 

between 5 a.m. 

and 5 p.m. PST, Monday through Friday.
