ASUS GT 640 2GD3 - 4 monitor output?

1 post in this topic

Recommended Posts

Hello There,


I want to enable 4 monitor output for asus gt640 (2gd ddr3 model)...


10.8.2 / cartri bios / graphicsenabler=no


1. First installed the card - only two outputs available


2. Installed 10.8.2 nvidia drivers - three outputs ok, wont boot with 4 screens, after boot i can plug the 4th monitor, working, but no wake after sleep.


3. So I installed a 8600gt for the 4th monitor - but now experiencing laggy UI because my pci express frequency is now 8x due to dual graphics cards.


Any solutions?
