ASUS TUF Dash F15 (FX516PM) - Intel Grpahics driver with wrong gamma

[hamish0211]

The model cannot output the 256 gray colors when I use the Type-C to HDMI or Displayport.

We update the driver to the last version. The error cannot be clear.

We test the 256 gray colors, there are three gray levels that have errors as below.

Image Input Gray = > Intel Graphics Gray output

Gray 16 = > Gray15

Gray 24 = > Gray23

Gray 254 = > Gray253

But, Nvidia graphics card output is correct.

Could you please help check where the issue caused the problem?

Thanks.

We have a board that can convert HDMI to RGB. We connect all the RGB output to LED. Then check the result through the gray image shown.
