    So I just finished installing Yosemite (fresh install), and I cannot for the life of me get my three monitors to work. I have a flashed 7950, reference, and I can get all four ports to work, just not more than 2 at a time. I also have a flashed 6870 that I can get 3 displays working with on my Hackintosh, but I still cannot get it to work on my Mac Pro. Any workaround?

    I'm going to guess that you are using dp to dvi adapters ? (Or the equiv)

    Call me Kreskin.

    If none of your displays have REAL DP input Google "active DisplayPort adapters"
