4 monitors in a matrix? or shared image?

[whatuusay1]

Has anyone setup 4 monitors to display a single picture? sort of linke a matrix? we have 4 large monitors setup in a 2x2 grid - They each have HDMI and VGA inputs. What I'd like to do is set them up to share a single input or hook them up to 4 video card outputs (2 to each card). Has anyone accomplished something like this or could give me some advice as to software or configuration options to acomplish this?

I've done it with two monitors and it's cool for a while, but the borders of the monitors get annoying after a while, having those black lines in the middle of the picture annoyed me, so I went back to separate desktops...

We're looking to use this for a loby display - trying to keep costs down (some of the enterprise hardware devices I've found are very expensive).

here's an example of what we're hoping to accomplish..

Dunno if you did but you might want to post this in the display section also.

Ok - I've been digging into this project all day and I found a couple of options..

1 - go with a 4 head video card (yes.. they do make them).

or

2 - pick up a matrix switcher which from what I can find is pretty pricey.

With windows display settings you can setup your desktop to stretch to the four monitors, so you can say set them up
12
34
or something like that and when you maximize a window it will stretch between all 4. If you have 2 pci express slots in your computer you can just throw in 2 pci express video cards, and windows should handle the rest, or if your limited to one pciexpress/agp you could always pick up a pci card for your needs, I dont believe they need to be fancy cards either.

you maybe even able to get three out from one of the new 9600gt's (havent tried this) 2 dvi one hdmi... and maybe use the last from the onboard if your lucky
