Third Monitor for Extended Desktop

If I purchased an external video card (e.g., IOGEAR GUC2015V External Video Card, USB 2.0), could it be used to extend my desktop onto a third monitor?

All the product descriptions for external cards tout their ability to enable a second monitor, but they never mention anything like "two or more".

Windows is only letting me enable two monitors at a time right now, so I assume I need another video card. For various reason, an external card would be much preferable for me. A hub wouldn't work, because I need it to be mobile. But I'm not all that technically educated - I just use the stuff. So, without a product description upon which to rely, I'm not sure a USB video card would work.

Thank you!

How to do 3 monitors (for 3d but that isn't important or is it?)
The IOGEAR GUC2015V will extend to a 3rd monitor,  Do you have it connected at this time, If so you should see a 3rd monitor in the display settings.

You would need a video card that supports two input connection for monitors (DVI, VGA, HDMI).  

Something like a Radeon HD 5 or 6 series would work.

I haven't bought anything yet, but I wanted to get input before shelling out for something that potentially wouldn't work.
