Dual GFX Card no screen detected

2 posts in this topic

Recommended Posts

Hi there,


Just installed OSX Lion DP4 for testing purpose, my config is :

X58A-UD5, i7 950 @ 3.2 Ghz,

12Go Corsair Dominator DDR3 1600 @ 1333

Nvidia (Asus) GTX 285

Nvidia (Asus) GTX 275.

-> Chameleon RC5 rev.1005


Install went OK everything working fine exept for the two graphic card.


On SL i used to do this with a custom gfx string but it doesn't work with Lion.

I also tried ATY_Init (32 and 64 bit) but the result is always a black screen.


When I log in using screen sharing i can see that both graphics cards are well recognised, but my monitors stays black and System Info tells me no monitor detected.


Hope we find a solution for this untill Lion comes out for real.


-> For those asking what's the point having two graphics cards I will already answer telling that i use DaVinci and Avid MC5 (DaVinci needs two GFX to work properly and MC5 can have a third screen for full screen monitoring).

I planned to test DaVinci with two GTX570 and a small third one later this summer :-)


Thank's for your help !
