Gamma Adjustment

When the gamma curve is a straight line:
The brightness and contrast of the video input will be the same as that of the video output.

Area for which the gamma curve is above the straight line (A):
Video output appears brighter than the input.

Area for which the gamma curve is below the straight line (B):
Video output appears darker than the input.

Area for which the slope of the gamma curve is steep (midtone) (C):
The grayscale range of the video output becomes wider, and the contrast increases (D D’).

Gamma Adjustment When Viewing HDR Contents (Tone Mapping)

“HDR(ST.2084)” gamma is the PQ curve adopted by HDR10. Fine adjustments can be made according to the screen size and environment although the default settings for viewing with the projector have been adjusted to allow optimum viewing.
