Adjust Gamma Settings

To access the gamma settings for your secondary input select Input and Switching >
Secondary Image Settings > Secondary Gamma Settings.
To access the Gamma Settings, select
Image Settings > Gamma Settings. The
system offers 2 types of gamma correction.
Gamma correction can be applied to a
specific source to correct for luma encoding.
This is the Gamma control. The system also
provides a global Gamma Correction
control. The global control offers an offset
applied to all displays. This offset is used to compensate for changes in ambient conditions, such as
ambient light in the room and projected material.

Gamma Correction

Gamma correction should only be adjusted to compensate for ambient conditions.
Gamma Correction applies a global offset to all gamma settings for each input. This offset is used to
compensate for changes in ambient conditions, such as ambient light in the room and projected
material. It affects the shape of the curve by performing a linear transform toward a gamma curve of
1.0 while the control is increasing and likewise a linear transform toward a gamma of 3.0 as the
control is decreasing. To correct a particular source only, use the Gamma control.

Select Gamma

Select the base gamma table
for a given source. Select from
one of the standard tables, a
custom gamma function, or
select an arbitrary gamma
table that has been
downloaded to the projector. A
separate PC utility is needed to
do this.
