So I have this setup where I am using a 1920x1080 monitor as my main one connected with dvi and my secondary monitor, a 1440x900 connected with hdmi. Now I realised I had an older monitor in the basement, also a 1440x900 I believe, so I dug that up and tried to connect it with a hdmi to mini displayport cable, as that was the only free hole in my graphics card, a 7950. Now the problem, If i go into Catalyst control center it only lets me have 2 of the screens active at the same time, any combination works but it wont let me have all three active. Am I missing something obvious? Note that this is not for eyefinity purposes

They are all flat and the main one is dvi to dvi, secondary is hdmi to hdmi and the "new" one is hdmi to mini displayport, so ive used the hdmi, dvi and the mini displayport
