how do it work? one monitor is in word, the other in a dictionary program, and the last in the internet. do you need something to do this one? i know my comp has two monitor ports but my video card can only use 2. do you need special things to this one?

ill post the video/pic of this one if i found it again.

I would assume they have two video cards in their computer, probably one with dual monitor support and an onboard one. This should allow for three monitors to be used for one computer. But three monitors is too much. Then again, i find just two monitors too much. If your motherboard has an onboard video card and is capable of having two other video cards, you could probably have up to five monitors. Good luck finding desktop space to place them all on, though. I wonder how that would affect your electric bill.

or, you could just buy a low quality pci video card... only instead of buying one buy like six
plug as many monitors as possible into each.... i think that would call for rounding up a few oldie crt monitors!

There is software availiable which basically allows you to drag from one screen to another! Which you would have to research yourself but its not hard! my school it dep uses it so it can be good!

But there are "screen spliter" devices that allow multiple screens to be seen by the computer as one screen, so that you might have a resolution of 2560x3200 or something because you put another 30" monitor on top of your existing monitor...

That way you can have a very, very large screen size, but you will need a very good graphics card to handle the resolution... especially if you are considering to play super-graphics-intensive-full-screen-games at every graphics setting to high...

Thats not software, its actually part of the os, or at least the drivers for the graphics card. The computer just takes the second moniter and extends your screen space onto it. You just need to specify the dementions of the second one and where in proportion it is to your primary one.
