a gamma correction value of about 2.5 to avoid color bleaching and burning.
The gamma curve correction formula is based on output level ∝ input level ^ gamma.
1. Enter the menu Home/Image, and select Gamma.
2. Use the arrow keys to adjust the Gamma value, until the colors seems to be perceived correctly. The default

Purpose
When blending images from multiple projectors, the perceived color coordinates of each projector can be
altered to a desired common level, so that the projected colors are identical over all projectors used.
Alternatively, if you are unfamiliar with how adjusting the Colors to a specific setting, there are also a certain
number of presets available, which forces the color output to specific color standards.
The selection of the presets will vary, depending on the projector type, and the color wheel installed.
