   Hello     First sorry for my bad english.

I have little problem with my motherboard B450 fatal1ty gaming k4. When CSM is disabled my Acer monitor says "Input is not supported" so I take a look on google and I found that the BIOS wants display in unsoported resolution. So i disabled Full HD uefi and restart it and nothing change. Can you please help me how to change the resolution? It only works on TV, where i can see that resolution is same.  The UEFI just ignores setting.
