I am running a Mac Pro Dual Core Intel Xeon and I am trying to get two 19" apple monitors to work on the one graphics card. The Mac is recognizing the other monitor, but it does not seem to be getting power, it is staying black. I have the little adapter on the back of the graphics card for that monitor, but I seem to be missing something. Any help would be greatly appreciated. :Confused:

No worries, the staff will move posts that are not posted into the right forum..:)

What connections do you have? You might want to search Google Images to find them and tell us about it if you don't know the name for sure..

Which graphics card do you have and what is it's supported resolutions?

Nividia GeForce 7300 GT 256mb. single link DVI and Dual link DVI, the machine is seeing both monitors and is saying that both are DVI but only one monitor is lit. Does it have something to do with the power supplies? Both power supplies are plugged into the wall.
