I have an issue with the external display of my laptop (HP EliteBook 655 G10). The screen plugged (BenQ GW2470) is displaying very bad colors. Especially the greys that become nearly white.
This make the use very complicated, because I cannot see the selected item, or some buttons are not visible.
The problem is the same with Windows, and I fixed it by adjusting the contrast value on that display with the ADM driver software.
I have spent a lot of time to set the contrast on my Debian, but I haven't found any solution (neither in the admgpu parameter, neither by importing the ICC profile of the windows).
- Do you have any idea to set the contrast ?
- Is it a missing feature of the AMD GPU driver ?
The GPU is a graphic car include in the AMD Ryzen 7730 U.
