simply put it doesnt work. you have to disable sli every time you want information to be send to display #2. i am pretty peeved over this because nobody has ever mentioned it to me before and i just bought a second card to use sli. seems stupid to me that you have to loose estate for added performance. rumors of Nvidia fixing this with new gpu's surfaced 2 years ago and yet nothing has been done. anyone wanna buy an 8800gts?
