i recently bought a dualg g5.

And the info about the video card is this:

now, i have 2 20inch cinema displays. There are two connectors on teh video card, one matchs right up, the other one, not so much. i tried going to best buy, circut city, and radio shack. They all dont have any adaptors or anything, but one guy said its a mac product, and the apple store would ahve it.

Now, i dont know the name of it, but i have a pic.


so basicly i need something i can plug into that, and then the other end mate up to the connector comming from my cinema disply.
