I just installed my 8TH linux distro because of the crap 3 4K monitor support and I decided to go with KDE Dra460ized. Only to see right as I boot up that the screens are overlapping each other. It seems linux doesn't really have good 4K support. I'm pulling my hair out because I need to get work done but no distro seems to play nice with 4K. Does anyone know a solution, if not I guess I'll have to get window which I really don't want.
Did you check KDE's monitor settings? Overlapping outputs normally means the displays are configured to overlap.
