3 Monitor Eyefinity "To extend the deskrop, a desktop or display must be disabled"

[TheEvaFreak]

So I have 3 ASUS VE247H 23.6" monitors.
My GPU is an XFX Core Edition FX-785A-CNL4 Radeon HD 7850.

I am trying to have a 3x1 monitor Eyefinity setup. That card supports up to 4 monitors. But whenever I try to enable a third monitor it says that it's unable to save the settings. I have tried switching the way the monitors are connected(DVI, HDMI, Mini display port --> HDMI). But I seem to keep getting the same result.

Any ideas?

Never mind I figured it out.

My card only allows 2 passive signals, the third and fourth have to be active. So I just need a new adapter.
