Video Wall options needed

We are putting up four 40" LCD panels in our conference room. We are going to be driving these displays primarily from a windows workstation with a quad output video card. I need to know what he advantage would be to using something such as the Gefen 2x2 Video Wall Controller or similar. Am I correct in thinking that I would only need the Gefen unit if I wanted to hook up another source like cable or DVD and have that source display as one monitor? I mean using the PC I can span a window across all 4 monitors and just do it that way correct?
Thanks,
Brian

depending on what you intend to display, the Gefen 2x2 may not do what you think it does.

That device takes 2 inputs and lets you select between them. it also shows the chosen output on 2 screens instead of one.
If that's what you need then its much easier to do that then to set up a PC for the task.

If you use a PC, you can do much more that the Gefen 2x2 can. (EG You can display different things on all 4 screens if you want to)

Could you advise what you actually want to do?

I anticipate using the displays as follows:

Option 1
I would want to use the four screens independently, which I currently do on my multiple display desktop so no problem there. Additionally I would want the option to span a window across all 4 monitors and have it display as one? For example span an application such as windows media player across all 4 monitors and show as one screen?

Some of the apps I would use
 - Powerpoint
 - Windows media player
 - Microsoft word

Option 2
This is my first video wall so I can only guess that I would want to take a source such as a DVD player or similar and play it across all 4 screens as one?

Option 3
Perhaps have some digital marketing display across all 4 screens as one, although I am not sure what format I would be using.

The Matrox stuff looks interesting but I don't quite grasp what functionality it provides over using a quad video card.

Thanks,

The matrox provides a connection/ controller if that's the language you use.. between the screens and the video card the software to control what is happening on each screen.
Take a look at the video guides I posted this should give you some insights if it suites your needs
I cant say what is possible with your quad video card.
What brand is it?
I looked at this video to familiarize myself with your interests, you understand the possibilities are numerous but it also depends on compatibility?

Option 3
Perhaps have some digital marketing display across all 4 screens as one, although I am not sure what format I would be using.<< digital signage, all that is streaming a video playing in a loop or powerpoint presentation like in cafes or real estate windows.

To achieve all these you would need a few different types of software.
Let me research some more for you,
If you could give your thoughts and what brand is the video quad core
cheers
