I'm having difficulty getting three outputs to work on my card. I have two DVI, 2 mDP, and 1 HDMI outputs on it. Im using the two DVI and trying to utilize one of the mDP ports using a mDP to HDMI cable. When pluging in the mDP though that takes precedence over one of the other DVI outputs and Im left with only two monitors functioning. Is there something I should be using instead? Not sure how to properly get this up and running. Thanks.
