I'm guessing you aren't using an active dp to DVI/HDMI adapter. I have the 7950/280 and to get all four of monitors workings I'm using two mDP to DVI adapters.

I said YOU aren't using an active DP to DVI/HDMI adapter. I have two mDP ports on my card so I have to use mDP. Please be nice enough to use the info I giving in a way that fits your hardware. You need an active adapter. Whichever for your card.
