I've been running eyefinity the past 6 months on 3 monitors on a XFX HD7990 but after encountering a crash when installing the beta 14.1 drivers I had to reinstall windows.
Following that reinstall I cannot get eyefinity to work. All I am getting are 2 screen setups.
CCC can see all 3 screens and I can set properties for each monitor independently. I cannot create an eyefinity group with more than 2 though.
All 3 screens are identical and are connected with active mini dp adapters, that are also identical. All 3 have been working fine for the past 3 months, but for some reason they dont any longer. I have checked the cables and they are plugged in etc. And as said, I can change settings for each monitor just fine.
I have tried the 13.12 WHQL drivers and the beta 14.1 drivers and both are unable to handle more than 2 monitors.
Anyone have any idea to what might be wrong? It is a clean windows 7 install, fully updated.
