Need help with AMD Radeon HD 7770 Setup

I installed 2 graphic cards to control 4 monitors. I think I am almost there :).

I am Using:

Motherboard: ASUS-P8Z77-V-PRO
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.

Thanks.

  1. It depends on whether or not you're crossfired.

    If you crossfired your cards, then all screens must be connect to the primary card, ie the one closest to the CPU.

    If your cards are not crossfired, then what's your PSU? Do you have the most current, stable drivers installed?
  2. The problem was with my adapter. It's working now. Thanks
