Eyefinity Suddenly Not Working.

I bought a new monitor mount and disconnected everything and reorganized my setup and now suddenly my Eyefinity has stopped working. I did a driver sweep and uninstall and reinstalled 11.7 and still nothing. Here's what happens.

Creating an Eyefinity Group puts all 3 monitors into clone mode. I get no other step to arrange displays. If I go to adjust screen resolution in windows it shows duplicate display on 1 and 3, but if I set resolution to 5760x1080 then eyefinity seems to work except the 3rd monitor is on the wrong side so the displays aren't arranged properly. If I go to desktop management in CCC then it shows all displays as 1, 1, 1. If I disable and then extend manually then the monitors work across all 3 displays, but as soon as I try to create an eyefinity display, it breaks again. What could be wrong?

Setup is

DVI
DVI
Mini DP to DVI

Everything was working fine before I reconnected all my monitors.

*EDIT* Ok seems my 3rd monitor is running in HDTV resolution according to CCC desktop properties.

*EDIT 2* Ok when not having my Mini-DP plugged in, everything works as it should when enabling 2x1 EyeF (Bezel Comp, Arrange etc). Why is plugging in my mini-DP for the 3rd monitor causing issues? It was working fine last week.

Tried swapping around the ports, switched some monitors around, still same problem. This is extremely odd and I have no idea what could be causing this.
 
Not sure if you're still having an issue with this. At first glance it sounds somewhat reminiscent of some of the bad DP cable/adapter problems I've heard people have. I'm assuming since you had it working prior, your DP --> dvi adapter is active; do you happen to have access to another one that you could test against?
 
No but here's the weird thing. I decided to try it out on my secondary W7 boot. I installed 11.8 fresh and saw that it was working just fine. It appears that something went wrong with the drivers on my primary boot of W7. I recently had to uninstall 11.8 and downgrade to 11.7 because of a game that isn't currently compatible with 11.8 drivers. Weird because I did uninstall from control panel and then driver sweeped all the remaining AMD drivers before installing 11.7. Not sure what's wrong still but I guess I am just going to have to try an even older version of catalyst.
 
I had the same problem with 11.8 then downgraded to 11.6 then plugged in my mini dp to DVI active adapter while the computer was on and everything worked. It was frustrating. I was working on it for 4 hours or so....
 
I'll have to try that one thanks. It seems all my effort was for nothing anyway since Deus Ex HR won't detect my Eyefinity setup even on a fresh boot of W7 with 11.8 and CAP 2. It won't center my HUD ><
