I have i7-10875H processor on my laptop. I have disabled the NVIDIA dGPU, so the problem is only about intel drivers.
I'm using Debian 11.
Tested with Kernels:
- 5.10.0-9-amd64
- 5.14.0-0.bpo.2-amd64
I have used both Xorg and Wayland, the notebook screen is stuck at 40hz.
But the screen is 165hz.
I think it is something about driver level because it doesn't matter about the Xorg configs or xrandr settings. Even if I set the hertz value 165 on xrandr, the screen still runs at 40hz.
How can I make it run at 165hz like on Windows?

I have tried creating new EDID file and xrandr Modesetting settings, they didn't work.
