Getting a screen flicker whenever I turn on my system or when the computer comes out of Sleep mode. The GPU I have is r9 nano in crossfire with another r9 nano. I originally thought the DP cable went bad so replaced it with a brand new one still keeps happening. Tried swapping card positions and different ports with the same issue. Tried Crimson Edition 15.12 and 16.1 hotfix drivers.
Monitor in question - LG 34UM95
Should be noted that I was running a GTX 780 and never had this issue until I switched to the r9 nano. Any questions or suggestions please, the cards are 4 days old and this is driving me insane!

I have tried ramping my 2D GPU Clock to 1000MHZ to match my 3D clock like some people have suggested on other threads but that did not work. The only fix I have somewhat found is to unplug my display port cable from slot one and move it to slot 2 on the gpu. Sometimes I only have to do it once sometimes 3 - 4 times. I have tried 2 Different cables that are brand new. I have tried different monitors but it seem to only effect my LG monitor.
Please any suggestions and help would be greatly appreciated asap being as I only have so long till I cant return the cards if it cant be fixed.
