7.6  Gamma
Gamma is the relationship between the color values of the data and the color values displayed. The Gamma
coefcient makes it possible to adjust the brightness of the mid-tones only without affecting the very bright and
very dark areas. If gamma is set too high, middle tones appear too dark. If it’s set too low, middle tones appear
too light. Depending on the current active Picture mode, the Gamma setting can be set to:
Numeric value from 1.8 up to 2.6
Normal: Standard setting for normal viewing.
A: Gamma curve that put more emphasis on the gradation compared to the Normal setting.
B: more emphasis on the contrast compared to the Normal setting.
C: Gamma C is brighter compared to the Normal setting.
HDR (Hybrid Log): for viewing Broadcast HDR (High Dynamic Range) such as BBC or NHK TV programs.
HDR (ST.2084): dedicated for viewing HDR (High Dynamic Range) contents such as UHD Bluray Discs.
Custom 1 to Custom 3: ne tune the gamma setting according to the user’s preference.
NB: when Color Prole is set to x.v.Color, gamma setting is xed to Normal.

Film 1: standard gamma.
Film 2: slightly enhances the darkest areas of the picture.
7.7  Advanced Gamma
Correction Value
