I just purchased a 4K monitor and having some problems to properly display a stable 3840x2160 @60hz via MST on displayport 1.2.
Sometimes the resolution of the screen reverts back to 1920x2160 (one screen? it is eyefinety in theory), mostly after a system crash in a game due the famous blackscreenissue and/or, after a reboot
. Switching the power on and off to the screen seems to help, not alway's, sometimes several attempts are needed, and after this, the desktop seems to be reorganized and windows 8(.1) autoscaling fails. Another reboot is requiered.
Also some games run only in weird resolutions, (Tombraider, DeusEx HR, and Hitman for example). The images in these games are stetched, others just just play's in a halfscreen? Some suggestions? I have GPU scaling on in catalyst settings and set keep full screen ticked on, is this the correct setting? Also set displayport on 1.2 in OSD of the monitor.

I tried to manually set a eyefinity groep at 2x1 but it doesn't stick all the time
3840x2160 @ 30 Hz seens to work right without any problems.
Is this known by AMD and are there some fixes coming in cat. 14.1?
Btw, I'm not blaiming AMD for this, maybe the problems lies within the OS or somewhere else.
Thanx for reading
