Very weird graphical problem

[IsidoreIsou]

Hey everyone,

My hack is working OK, but since I've installed Sierra, I have this very weird graphical bug (see picture).
It never happened in El Capitan.
I have 2 screens : 1 UHD@3008x1692 DP + 1 FullHD@1920x1080. My graphic card is MSI Strix 960 4GB.
This problem is only on my UHD screen, AOC IPS 32" display.
When it occurs, I have to unplugged my display port cable, restart the computer, sometimes the screen is stuck at 30hz, and then it comes back to normal for a few days.
I updated my Nvidia drivers, after that I thought the problem was fixed, but this morning it comes again.

Ideas :
- I installed CUDA yesterday, do you think it might be the cause ?
- Is it a hardware problem, graphic card or screen ?

I would appreciate very much if you could help me !
Thanks !

May be caused by EDID detection, like my system, try resxtreme.app may help, switch different resolutions and pixel colour depth with resxtreme.app, just double clicks supported resolutions, it will update system EDID, very useful for dual monitors system.

If not help, may need edit FB@ patch, change connector type to 01000000 (it work for me with different ratio monitors), can prevent many problems while dual monitors setup, after setup success, change back connector type to 00040000 to DP.

Sorry, I make a mistake, I forgot your system is DGPU, dual monitors setup, work for IGPU only.
