> Hello,
> 
> I have an Optimus laptop with Intel Tiger Lake H GT1 integrated graphics (i7-
> 11800H) and NVIDIA RTX 3080 Mobile GPU. The inbuilt display is 165 Hz and is
> connected to the IGPU by eDP. As of any Kernel version 5.16 onwards, Xrandr
> only detects 60 Hz as a possible refresh rate. The problem also occurs on
> Wayland. Downgrading to 5.15.13 resolves the problem.
> 
> Another user of a laptop with similar specs also reports the same issue and
> provides Xrandr output: https://bbs.archlinux.org/viewtopic.php?id=274012
