2 Graphic cards Crossfire only 2 out of 3 monitor on. HELP!

post #1 of 6
Thread Starter 
Running all the right driver for the XFX ATI 7770 graphic card. When I open the Catalyst Control Center application. There's a tab that ask me if I want to "Enable AMD CrossFireX". When I click on "Apply" only 2 monitors are display and the 3rd one is not.

If I click on "disable AMD CrossfireX" all monitors come on. I have the crossfire bridge on both of my cards.

2 monitor = 1 x XFX 7770
1 monitor = 1 x XFX 7770

I thought that I'm suppose to crossfire both cards to get the best performance?

At the moment, I had to disable the crossfire in the Catalyst Control Center to have all 3 monitors working.

Or should I put all 3 monitors into one card and crossfire it with the other one for maximum performance?

Is that the correct way to do it?

All three monitors have to be connected to the primary video card (slot 1). For some reason AMD only allows all connections to the first card.

Yeah. When I had an eyefinity setup with my 6970s I had to buy a DP to DVI adapter.

Is there more performance gain with all 3 monitors hook up to one graphic card then crossfire it with the other one? Or would it be better not to crossfire them and run

2 monitors - 1 graphic card
1 monitor s - 1 graphic card
