Custom Resolution Utility (CRU)

[brandi87]

Hi,

since my latest windows update (a bigger one... 1903) I'm no longer able to use the custom resolution (4k) on my samsung screen via HDMI.

I've used to have 3840x2160 (30Hz). But since my OS update the resolution is not selectable anymore.
When I open the CRU utility, I can see the detailed resolution. Even if I delete everything, execute "reset all" and restart my computer. I still can see this 4k detailed resolution (see screenshot). So I think it could be there is some orphaned setting in registry or somewhere else.
Already executed DDU and reinstalled all drivers (AMD RADEON 6850). Still no success.
Do you have any hint for me?

Thanks in advance and best regards
Roland
