I just recently picked up 3x Nixeus NX-VUE24B monitors and have them connected to one of two Sapphire R9 290's. All 3 monitors are connected to one GPU with Crossfire enabled and when all 3 monitors are turned on they just flash randomly going in an out of signal.
This is where it gets weird, if I only use 2 monitors both connected via DVI they work normally. If I use DisplayPort and DVI the DVI monitor in Windows Display settings appears and re-appears constantly. However if quick enough I can select the DVI monitor and extend/mirror my desktop both monitors will work.
So now with both monitors working I turn on the 3rd DVI monitor and all 3 just go crazy in and out of signal.
Anyone have any idea's?
I've tried the following:
Each GPU separately with Crossfire disabled
Removed 1 GPU from the PC
Windows 10 & Windows 7
Crimson & Non-Crimson Drivers
