2. Ensure that all projectors are color-matched.
If necessary, use the
White Field
test pattern and test the light output of each projector.
Ensure the

Use
Lamps > Lamp Power
to compensate for different lamps. Even identical lamps change their light output with age and use.
3. Enter the correct gamma setting.
Adjust the gamma setting using the
Image > Gamma
control. For video sources, such as Blu-ray or DVD, use a value of
2.2
; for
computer graphics use
2.4
.
The images may still look slightly different at this stage. It is OK to continue.
