Hi,

I've got a Geforce GTX 560 Ti Phantom with 2048 MB Ram from Gainward. Single display works fine with mountain lion but i need the other dvi to get a dual screen system. How can i get the seccond DVI port working? DSDT edit? Some kexts? Boot options in chimera?

Thanks

Whohayyy! It works ;)

Here is my little HowTo:

1.) Download and run GPU-Z (in Windows). Click on the tiny right button to save your gpu-bios as a .rom file. (You can use the posted rom from sammikhail above or download it here: http://ul.to/7y18aw1i)

2.) Put the Nvidia ROM at: /Extra/<vendorid>_<devid>.rom (in our case name it 10de_1200.rom)

3.) in the /Extra/org.chameleon.Boot.plist add or change

<key>GraphicsEnabler</key>
<string>Yes</string>

<key>UseNvidiaROM</key>
<string>Yes</string>

<key>VBIOS</key>
<string>Yes</string>

4.) Reboot your machine and have DualDVI working ;)
