I'm trying to set up dual monitors from my Firepro 5100 and nothing seems to be working. They are both identical brand new monitors, the primary(which is working) is hooked in with a DisplayPort cable, the second (which won't even show up as detected) is DisplayPort adapter to DVI to DisplayPort adapter,. both adapters came supplied with the GPU. The second monitor works as a primary when plugged directly in, so there is nothing wrong on that front, this seems to be a problem with the gpu specifically. Any ideas? I bought this damn thing specifically because it claimed to be able to do this, and now I'm just wasting time I don't have.
