I'm trying to hook up three monitors to my XFX 7850. From what I've read you need an active display port adapter to accomplish this with two DVIs and one display port to DVI. I have 3 dell p2310H monitors and they all have display ports. If I hook two of them up to the display ports using a standard mini display port to display port cable and the third up to DVI do I still need a special display port adapter to accomplish this? I wanted to check before I ordered the cables from new egg. Thanks for all help.
