4 1920x1080 DVI-D Displays

I would just get an ATI 5970 and get adapters for all of your DVI-D cables, run those four monitors in eyefinity and basically you should be good to go.

Theres more to this than that, right? There are professional systems that there is no upperlimit on and there is the do it yourself stuff - which is what this seems like?

Are we displaying the same image on all 4 monitors or different images on all 4? Full screen displays or windowed? OS?

Whats the goal? Use this compact box or 4 displays - define what the objective and we can work towards it.

Take a look at this site for a isting of 4 port video cards - http://www.multiplemonitors.org/Pages%20-%20Hardware/Ha...

Good luck

It will be 4 monitors with different images in full screen display. In the past I have used a Jupiter multidisplay unit. This is a little more low budjet. The compact size of the pc is because it will be mounted behind the monitors that it is controlling. It does have to be 4 monitors.

On the website the specifications for that card says this:

ATI Eyefinity multi-display technology2,3
Three independent display controllers
Drive three displays simultaneously with independent resolutions, refresh rates, color controls, and video overlays

Will it run four monitors? It looks like only 3.

well you could use one of these, once they get them to stores...

though you'll need a bunch of (active?) DP-to-DVI adapters.

I thought it could run six, but I must have been mistaken. It must have been something else I was thinking of, but I'm not completely sure what.

Do you plan to game on these four monitors, do website design, photo or video editing, or just plan office work? Or all of these tasks at once?

I'm going to stream live video from an IP video surveillance system to them.

that would be the eyefinity6 edition with 6 miniDP outputs, afaik it hasn't been released yet...
