After a while of running 3 Monitors in extended desktop I decided to set up Nvidia Surround for my tri sli gtx 580s. Going into Nvidia control panel get the following screen showing only 2 cards possible for sli. So I went into the configure screen which again shows only 2 cards available or sli but states the attached screens wont be used. This shows setting up the screens to 2 cards but i assume that if i do so then sli will be running off of 2 not 3 cards. I have the screens set up 1 per gfx card as required last time i set up surround. I'm probably missing something obvious but does anyone know how to solve this. Was using 280.XX drivers and have even reverted to 275.33 to try to solve this but no joy.
