So I currently have 2 7770s in my computer. Crossfire bridge is connected, and crossfire seems to be working. However, I cannot use more than 2 monitors. I have 3 hooked up, 2 to one card and 1 to the other. The 2 on the "main" card turn on fine, but the third one won't get any signal.
The interesting thing is that I can run all 3 of them when I first install the drivers just fine. When I finished installing the drivers, all 3 monitors just turned on by themselves. Once I restarted though, I can only use the ones plugged into the top card and the third monitor goes blank.
Does anyone know how to fix this? I've tried nearly everything I can think of. I've tried detecting displays, installing one card, the drivers, then plugging the other card in, etc... None of it works after a restart. I'm quite sure both of the cards are good, as I have been using 1 for about a year now, and I just bought the other one, and have been using it by it's self for a few days with no problems.
It has to be a windows setting somewhere or a bug, because it can obviously run the 3 monitors just fine.
Thanks for looking!
