I've just recently assembled myself a new Mountain Lion Hackintosh, and almost everything is working perfect, except OS X won't seem to allow me to use more than two monitors.
My build contains
- Intel Core i7 I7-3770K 8 MB
- Gigabyte GA-Z77X-UD3H
- Gigabyte GTX 670 WindForce OC
The GTX 670 has 4 outputs: 2 x DVI, 1 x DisplayPort and 1 x HDMI
Currently, I have two monitors connected, both using DVI. When I connect a third monitor using the DisplayPort, one of my DVI monitors simply goes black, and I don't know what to do about it or where to even start. The GTX 670 worked right ouf of the box with full acceleration after installation.
Any ideas on how to make GTX 670 detect and use the three monitors simultaneously? If that's not possible, I'd alternatively just like to be able to connect the third monitor to the integrated HD4000 graphics card. I have tried this, but OS X seems to completely ignore the HD4000, even if I disconnect the other monitors.
I use GraphicsEnabler=No and iMac 12,2 system definition, because I get a kernel panic with Mac Pro 5,1.
Any help is appreciated! :-) If you need any additional information, just ask.
