Use the Advanced Image Settings submenu to make the adjustments necessary for lesser-used but more
specialized applications on your projector.
GAMMA SETTINGS
The system offers two types of gamma correction. Gamma correction can be applied to a specific source to
correct for luma encoding. This is a channel setting and reapplied every time the same signal is detected. This
is the 'Gamma' control. On the other hand the system also provides a global Gamma Correction control. The
global control offers an offset applied to all channels. This offset is used to compensate for changes in ambient
conditions such as ambient light in the room and projected material.
• GAMMA CORRECTION
Applies a global offset to all gamma settings for each channel. 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. The control should only be adjusted to compensate for
ambient conditions. To correct a particular source only, use the Gamma control.
