I am trying to get 4 Dell 2410 monitors to work with my 4 port eyefinity card. All four monitors are connected via mini-displayport to display port cables with the latest drivers and software installed on windows 8.1 x64. Currently one two of the monitors are detected (it doesnt matter which two are connected) the other two monitors are not receiving any signal from the video card and just show no cable connected, however when the two functioning monitors are disconnected the other two start to work.
Given that I am using dispayport all the way to the monitor with no adapters from what ive read everything should be supported and the card should be able to run four monitors connected via dp. Any guidance or recomendations would be very helpful. Thanks
