I installed 2 graphic cards to control 4 monitors. I think I am almost there .
I am Using:
Processor: i5-3570k (Ivy bridge)
Two graphic card: Both Diamond diamond radeon hd 7770 (Has 1 DVI port, 1 HDMI port and 2 Display Adapter port)
I can get output from the DVI port from both the graphic cards simultaneously. However none of the other ports are working on either graphic card (I.E. Neither HDMI port or Displayport on either of graphic cards is producing any output). Please let me know what is that I am doing wrong.
