Hi, I'm also trying to output 4 displays from my HP Z230 (Core-i7, 16GB RAM)
It has a Quadro K4200 pre-installed and I want to add another AMD W600 (it has six-mini Display Ports).
First of all its a difficult job to remove the Hold Down Bracket from chassis. I've done it once, installed the card, but now when i try to remove it, it doesn't come off.. Help in this regards is required please.
I also wanted to check the Matrox M9140 (Quad Displays), but can't because I'm unable to remove the bracket.
Another problem is, when i connect the four displays, theyt keep on connecting and disconnecting...
I'm stuck..
