After updating the drivers on amd ryzen 7 5700g with radeon graphics, lost choice to select 120Hz for 4K display 3840 x 2160 , there are only 60Hz and below.
There is only a choice of HD = 120Hz, when switching the monitor to 4K, choice to 120Hz disappears
In Windows 11 - 64-Bit and Windows 10 - 64-Bit the problem is the same.
I don't use any graphics cards.
On old drivers you can not enable HDR on new drivers there is such an opportunity, but there is only 60Hz, for a 4K display a bad solution.
How to get 120Hz for 4K display?
