Using displayport & crossfire? Questions!

[Vanilla]

Hi all,

I just bought a new monitor and want to take advantage of 60Hz. I have just been using DVI cables until now.

I have two 7850's in Crossfire mode. The secondary card (lower one) has display ports while the primary one does not. When I tried to use the displayports nothing happened.

Some questions:

I had read that to use displayport with crossfire it must be one the primary card? Is this correct?

Do I need to swap the cards physically or can I switch them in CCC somehow?

TIA

I am only trying to connect to one screen - a new Samsung curved jobbie. I just want to take advantage of 60hz and hence the Q.

Guess i'll have to swap them around!
