The Elvidge Family

I had always wanted a 3 screen LCD display which I have found invaluable for studying and working as I can have many different sites, files, images and programs open at the same time. Before I used two computers to do it using VGA and DVI outputs. Check out my picture showing the current set-up which all runs from my HP pavilion laptop.
Here's how you do it:
You will need 2 x sewell USB to DVI converters that cost around £100 each. They can be hard to source, I think I found mine on Amazon marketplace being sold direct from Sewell. They come with drivers and software that make managing the two extra screens very simple, and you can also turn screens by 90 degrees for better page reading which I did for a while.
I am running on Win XP Pro with 2GB RAM with the central display running from the laptop's VGA output. The side displays are run from the adaptors and give very good graphics output (run through a powered USB hub. Suitable for video and multimedia, meaning I can comfortably use either screen.

I have also found that UltraMon is a very good utility for working in multiple monitors - easy multiple taskbars & switching between displays.
