Eyefinity AMD R9 280x. Help.

[xxMenime]

I have the Asus R9 280x. I'm trying to hook up 3 monitors.

All three have hdmi ports. So I tried using a DVI to HDMI on one. Then a HDMI to HDMI on the other. And a Display Port to HDMI on the third.

It won't allow me to have all 3 active at once. Help?

You need an Active Adapter for DP-HDMI. If you have an old version of the 28th it's just rebanded 7970ghz which does not support this setup without active adapter.

I bought this stupid graphics card a month ago. I figured Asus would be making the newer model. Apparently not. I ordered one of those though. Hopefully that fixes it.
