I've written on the virtues of dual monitor set-ups before. The problem for most of us laptop users is that we only have one VGA port available for adding a single monitor (using the laptop's screen as a second monitor). While that's a great solution, it's not quite as nice as having two identical screens side by side. Samsung had one potential work-around to this limitation, with their USB monitors and Matrox had another with their Dual Head2Go (which tricks your computer into thinking two monitors were actually one).
Now comes what may be the best solution yet -- USB video cards:
We're all about multi-monitor setups...once you go dual, single feels a fool. But if you're on a laptop, or don't have any slots available for another video card or just are on a budget, then an external USB vid card like this one from UV Plus+ might be the solution for you...You can buy them for $81 online.
The diminutive USB 2.0 powered accessory uses Displaylinktechnology, supporting both DVI and VGA at up to 1280x1024/1440x900 (UV12) or 1600x1200/ 1680x1050 (UV16) screen resolution. The units are even magnetic, so they can be safely and securely stacked.
Here's a photo showing the monitor port to give you an idea of how small they are:
The question is -- how well do they work?
