I came here with the same problem. When I open the UE Editor and navigate to my “Unreal Project Browser” my screen turns black for some seconds when I hover over any of the menu buttons. I tried to enable my HDR and it seems to work so far. I don’t know why exactly this happens. My plan was to watch tutorials on the second monitor (which is not HDR) and work with the engine on my primary monitor.
So if anyone knows why this happens and maybe can explain this to us, it would be very appreciated =)
