I got a problem. When I switch into Fullscreen (STRG F) the backround is not black.
It is some grey. I am using Win7, Rersolve free Version 12.5.6 (Latest)
I also reinstall Resolve... but it is the same.
It is a 2:1 Format. 16:9 Monitor. Same when I switch to 4:3 Format or 1:1 Format.
The backround is still grey, not black.
