Currently had two Acer monitors and want to run dual as I did with my last system. Just got a HP H9 1315T with a 7670 card in it.

I tried running a DVI to DVI from one monitor and DVI to DVI+DP adapter to use the DP adapter and the Catalyst control system isn't recognizing the second monitor.

The DP just doesn't seem to want to work at all with the DVI to DP adapter even though it worked on my last computer.

Any ideas on how to get the DP to work with the DVI to DP adapter or why the DP doesn't seem to be putting out any signal?
