I have an R9 280 and am currently running 2 monitors on it and am looking to hook up the third one that I ordered but I realized that the adapter I got for it was not active. The monitors I have dont have displayport. I will have three monitors, one running from an hdmi to hdmi cable, another from an hdmi to dvi-d, and am going to hook up the third one with an hdmi cable to an active displayport adapter into my gpu. Will this work for eyefinity? I heard that you must have an active dvi to displayport, is this true? Will my active hdmi to displayport adapter be fine?
