doesnt work in 3-way sli as far as i know. you should try the cards in single mode or just plug 2 cards in sli-mode and let the 3rd card run solo and then plug 2 screens to the sli-cards and 1 screen to the solo-card
2 screens -> 2way-sli cards
1 screen -> solo card
or
2 screens -> 1st solo card
1 screen -> 2nd solo card
to make it clear :oops:
Do you mean that I can only get an extend desktop on 2 screens and another solo?
Does this also mean that an extended desktop won't reach the 5760x1200 res across 3x 24" monitors.
Lastly, got something back of my head about the windows task bar stretching across 3 screen, this is not possible right?
