I just recently built myself a new machine now running Mountain Lion, thanks to the guides here!
I have a problem, though. OS X will only allow me to use two monitors at a time with my Gigabyte GTX 670 WindForce OC, even though I have three connected. 2 with DVI, one with DisplayPort.
When I boot up with all three plugged in, one of the DVI's will be black, so only the DisplayPort and the other DVI will show anything. If I then unplug the DisplayPort, the other DVI turns on as well.
I'm not sure how to fix it or where even to begin. Could system definitions matter? (Running iMac12,2). I have considered EFI String Injection, but I haven't been able to find anything relating to GTX 670.
In my build, I have an Core i7 I7-3770K, so if the above isn't possible, I'd be happy to just get the third monitor working using the integrated HD4000 graphics card, but OS X doesn't seem to know I have it (only the GTX 670 shows up in System Report -> Graphics/Displays). Even when I disconnect the other monitors, and enabled the HD4000 in the BIOS (Tried both with Automatic and Enabled), nothing seems to work. Only when I remove the GTX 670 from the socket, the HD4000 works.
Any help would be greatly appreciated!
My installation is a clean ML installed with UniBeast and MultiBeast.
EDIT: I just realized this should probably be in Post-Installation -> Graphics instead. Sorry, please move it!
