Unisex Posted October 20, 2010 Share Posted October 20, 2010 Hi there, I want to use 3 monitors on my hackmac. Last weeks I used 2 monitors with my GF 8600GT 512MB. Now I also picked up a GF 8600GT 256MB. I used for both of my graphics an EFI-String with EFI-Studio. So if I start OSX I can just use my both monitors from the last weeks. OSX can not display something to the 3. monitor :-/ So have I to do something so use the 3rd one?
