I recently built a workstation pc for my dad with dual ASUS HD7850-DC2-2GD5-V2 video cards. This version of the card has two DVI ports on the card. The intent is to run four monitors off the two cards on Windows 7.
I could not test the multi-montitor setup before I gave the PC to him. When he got home and hooked it all up, only the two monitors on first card on ports 1 and 2 card are working. The 3rd & 4th monitors on the second card are not receiving any signal. Is there some sort of configuration option I need to choose to get this to work? I installed the crossfire cable across the two cards. Is this not needed for this type of configuration? The motherboard is a ASUS P8B WS with a Xeon E3-1275 V2 chip.
