HELP! Cant use dual displays with 7950's in CF

post #1 of 12
Thread Starter 
Hey guys, so I just got two 7950's today and I'm having trouble configuring my two displays. My primary display is a 120hz display that uses Dual link DVI, and my secondary is a monitor that uses VGA (with a DVI to VGA converter to connect to the card). I have one display connected to each card, however my computer isnt recognizing the secondary display connected to my second card. What should I do to fix this?

They are both monitors. I need dvi for my main monitor for 120hz and dvi on my second one because it doesn't have HDMI. I guess I'll have to buy adaptor
