I want to attach 3 monitors to my computer, but discovered that i had to have an active displayport to hdmi converter if i wanted to do this with my 5770 card. So i then installed my old, Radeon 4650 card in my computer, and turned on the computer again. It booted up, and the drivers for the 4650 card were installing. A minute later, windows prompted me to reboot. After the reboot, the 5770 card was not working, and i was not able to run Catalyst Control Center. It told me that there were no working drivers for this card. (which have always been working).
The new drivers for the 4650 card is called:
ATI Radeon HD 4650 (Microsoft Corporation WDDM 1.1)
So my question is: How do i get these two graphic cards working at the same time? Do i install the catalyst software suite, which is compatible with the 4650 cards? Or is there a way to get my previously working CCC install, to run with both cards?
I am running windows 7 64bit.
I really hope someone can figure out this problem.
Thanks in advance.
