I have two monitors that match exactly. They are actually LG tv's. I have each monitor hooked into a Matrox DH2G DP edition with HDMI at the TV end and Display Port at the DH2G. I have a HDMI cord coming from the video card (480GTX) to another cord. This cord has HDMI at one end and Display Port at the other, which is then plugged into the DH2G. Power to the DH2G is USB.
I have downloaded the latest drivers and have run the setup but no glory. The only way to see my windows is by using my old DVI cord converted to RGB.
side note:, my TV's cannot detect DVI
side note:, I want to be able to stretch my desktop thus the reason for this setup.
I wonder if someone has first hand experience with this type of setup. I would give my phone # if it would be easier for a walk-through.
Thanks for taking the time!
