O.K., I found this solution on another forum and believe it or not, it works! I have an HDMI cable, I get no display. I have a DVI cable, get no display. I use the DVI to VGA connector and I get display...
Here is what the other guy posted:
It seems that i am writing a similar solution that worked for me. I had the same problem as you did but on three cards. they will not display anything even a post screen. My monitors would just stay sleep where my card blows air.
I posted this solution a couple of minutes ago on a couple other threads. I hope this could work for you. What i did was grabbed an old 945 intel Chipset and chucked the card in. there was no Boot and same problem. I then decided to use a DVI to VGA adapater and KABOOM bro.. it finally displayed somthing on screen! i then took the card out and teested them out on my systems on an M4A79T and an M3A79T!! they all functioned perfect and well with display ports and dvi all working as normal on windows 7 and vista using drivers from last month i think.
I hope this solution can work for you as it did for me. I did almost 6 weeks of trial and error and i am Happy this worked!!!"
Any suggestions at to where to go from here? I would hate to have this great new monitor and good video card and have to connect it like this.
