Crossfire eyefinity setup

[Guest]

Hello,
i bought 2 hd xfx 6870 dd edition to my first pc build and run my 3 monitors, but when i connect 2 to the first card, it works, but no picture on the third screen that is connected to the other graphicscard, is that card broken?

For AMD Crossfire eyefinity you need all monitors connected to the same card. Make sure you follow AMD's guidelines for connecting three monitors to one card - read the 2nd paragraph 'Connectivity Requirements': http://support.amd.com/us/eyefinity/Pages/eyefinity-dongles.aspx
