    Question P5Q-E Crossfire Help

    I put two ATi 5770's, powered them with an 850w PSU, set ATi control panel to enable crossfire, connected them with the crossfire cable. However, I can not get the other card to display video to my other monitor. They both show in device manager, but only one shows up in display properties and CCC. Any ideas?

    What operating systems are you using?

    You still have to enable dual monitors and extended desktop. Just because you are using crossfire doesnt mean you can right away use two displays. Crossfire is two cards working together as one.

    Windows 7 64 bit. I can plug in a second monitor into the same video card but not the second video card. I can also switch both monitors to the other card but I cannot run monitor A on card A and monitor B on card B.
