First off I have a XFX HD7870 Black Edition video card which has 2 DVI, 1 HDMI, and 2 mini display ports. 2 of my screens are TV's the 3rd screen is a standard VGA monitor. I have my main TV using the HDMI. The second TV is using the mini display port which has a mini display port to HDMI adapter on it. and the monitor is hooked up to the DVI port with a DVI to VGA adapter.

Duel screen between any of the screens works fine however when I try to add a 3rd windows will not allow me to apply the settings. The 3rd monitor shows up in screen resolution settings but when I try to extend desktop to this display I get the following message when I try to apply the settings. "Unable to save display settings". Also the Catalyst Control Center only detects 2 displays.

Here is a screenshot of the problem:

Do I need Eyefinity for 3 displays? I am not needing to use all 3 displays for games I just want the 3rd monitor working for the desktop.

I don't think its an Active Displayport to HDMI adapter. This is the adapter I got: http://www.amazon.co.uk/Mini-DisplayPort-to-HDMI-Adapter/dp/B003BERYLA/ref=sr_1_2?s=electronics&ie=UTF8&qid=1378212434&sr=1-2&keywords=mini+display+to+hdmi

I should also mention that the 3rd monitor is not using the mini display port to HDMI adapter its just a VGA monitor which I have hooked up to the DVI port with a DVI to VGA adapter.
