Here is a great article section I found at Multi-Screens.com (A beginners introduction to Multiple Monitors)

The Three main ways to Setup Multiple Monitors

1) You can buy a pre-manufactured multiple monitor computer. The best place to purchase a multiple monitor computer is at:
Multi-Monitors.com. They carry a multi-monitor computer line called SUPER-PC that can support from 2 to 12 monitors.

2) You can get a USB to VGA Adapter, or USB to DVI Adapter that will allow you to add an extra monitor to your computer
via any USB2.0 Port. You can also add multiple extra monitors by using multiple adapters. This is a great option for viewing
documents, surfing the web, using Microsoft Office and many other business tasks. This is not a good option for intense
graphical situations such as HDTV, Blu-ray, Gaming and 3D / CAD Workstation applications. For those types of scenarios,
it is highly recommended that you purchase a high-powered multi-monitor workstation or a Matrox Dual or Triple Head2Go.

3) You can replace or add an extra video card to your existing computer, depending on how many monitors you wish to support.
Although this sounds easy enough, this is a rather complex solution for a beginner, especially when trying to find a compatible
graphics card. For this reason, I am going to write an entirely seperate post on that topic and will link to it here, very soon.

Once you have your multiple monitor system set up and ready to use, you will need to enable all of your monitors in
your “Display Properties” Control Panel. Here is a great link to a complete and animated walkthrough of how to enable
your multiple monitors in Windows.

Wow- I think this must be close to a record...

We have to give him credits, he's probably the best forum necro around. I mean 7 years old threads resurrection isn't an easy feat. Especially if he didn't notice it.

I was wondering when I saw the Descent 3, I thought, did they make a new one? I never kept track of the numbers, I just knew Descent.
