My computer is a little over 4 years old now and has 2 Radeon HD 7900 cards in it. I need the crossfire option so i can see my second monitor. Right now I can't find it anywhere in the crimson software. The eyefinity option says my computer isn't compatible. I didn't even want to install the new crimson software and drivers. It was auto updated either by the amd software or windows 10. Anybody have a solution for this? All tips and suggestions would be greatly appreciated. I installed older software and drivers. Putting me back to the 15.30 drivers. However it seemed to install Crimson along with it. The amd software detects both video cards but won't display both computer monitors. When crossfire is off both monitors work. I just want to have both my monitors working again. Even if this means making it happen without crossfire. ALSO, the AMD crimson software detects both cards. However it doesn't seem to know there is a second monitor connected.
