Starting with Win98, you can put multiple video cards (even fairly cheap ones) into a computer. According to the documentation, Windows can handle up to 8 monitors.
I did this for a sportsbook for which I used do work. The frontdesk manager computers had two monitors each. This allows the managers to view lines on one screen and take plays with the other.
Notes:
1) Some cards act flaky with each other. I've even had to swap the order cards were in to get it to work.
2) Sometimes the built-in video of the mother board causes problems.
3) Extra memory helps. Also, don't run the screen at maximum color resolution. 256 colors is fine for reading lines. More colors=more memory=more time to draw screens=slower response.
4) I don't know if you can use 2 dual-video card and get 4 screens.
Despite the problems, very cool using two screens off one computer.
