Dear community,
I did the update from the latest v8 release to v9 which was running very smoothly. The only problem I have is, that I can't switch the display resolution of the UI to 3840x2160 any longer. The resolution is offered in the menu but the switch is not successful.
In addition, playing 4k content often fails and has now massive dropouts and artefacts.
Does anyone else face these issues?
