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
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.
