Gamma
Use the Gamma setting to adjust the value of the gamma applied to incoming video signals. The default gamma value is 2.2.
Gamma correction represents the relationship between the pixel levels from your incoming video and the luminance of your
monitor. The lowest gamma level available, 1.6, will cause the image to appear brighter. The highest gamma level available, 2.4,
will cause the image to appear darker. The chart below shows this on a scale.
