I am trying to setup crossfire on my two 5750 cards. I am using the 2 DVI ports and the VGA port. The VGA monitor cannot be turned on unless one of the other DVI monitors are off. can someone please advise what i should do. Thanks in advance
To connect 3 monitors to an AMD card, you can only do so with video cards that include at least one mini-DP port. This is your issue. You can run in non-crossfire mode and hook the third monitor to the 2nd card, but you won't get three monitors to run off one card without a mini-DP connection on the card.
