I think you can only have one monitor if you have more than one graphics card. Thats the way mine is anyways. I can have up to 4 cards.
yes you can do dual monitors in crossfire but you will ahve to use both connections on the main card of the setup. atleast for me thats how it works ^^ Smee
CF has to be off, and I think both monitors have to be plugged into the top card. For CF to be on you need to be using Windows Vista.
