I have an AMD Radeon 7900 series, which should support up to 6 screens. I'm having problems getting my third one working.

Im running windows 8, and have installed all the latest AMD drivers.

My screens are:

  • Samusng syncmaster S27D391HS
  • Samusng syncmaster S24B350H
  • Samusng syncmaster S24B350H

The first 24" monitor I use HDMI to DVI cable. The second 24" I use VGA to DVI cable. Lastly, for the 27" I use HDMI cable.

The result is, no matter what I do, I never get more than two screens on simultaneously. I have also tried getting a DisplayPort to HDMI cable to use for the 27", but Im not sure if it was passive or active (didn't say on the box, nor did I ask).

So my question is: is an active displayport to HDMI the solution, or is there someting else Im overlooking?

(I have read similar posts on this subject, but I use a slightly different combo of cables. That is why I made a post of my own as well)
