ChrisWebbTech yes I have tried switch monitor hookup and even tried only having one monitor hooked up. The only thing that seems to work is reducing resolution

Sooo, are you getting errors? Locking up, what's it doing?

Have you tried switching your monitors around when it comes to primary screens and or position, maybe try duplicating and see if it happens etc.

It's not just the resolution because I've got 2 x 2k and working fine. I mean it could be resolution with certain graphics cards or something. I'll do some digging when I get to the office and see If i can find some similar setups. What graphics device / driver are you all using?

    Ahh, didn't notice it was Ultrawide resolutions not 2k. Anyway, I got a response back that Microsoft is aware of issue and working on it. No ETA on fix.
