Worked prefectly in gaming, Adobe After Effects, Sony Vega. Don't really mess around with PS, so idk. What I do know is that you can find a TH2G for 200-300 easy, you wont have to upgrade your GPU (unless you want to) and it splits your 1 x digital signal into 3 x digital signals. They way your attempting to go about it, will likely end up with you having 1 digital signal and 2 analog signals, which is not optimal for what you are trying to do with 3 displays. IMO try it out, and if you dont like it, send it back for a refund.
