NewerTech USB Display Adapter [USB Dongle Lets You Add Up To 6 Monitors, DVI, VGA, HDMI ports]

If you have a desire for more monitors than you have video outputs, then you’re in luck as NewerTech has released a USB Display Adapter. The little gadget has a USB plug on one end and a DVI port on the other, allowing you to add as many monitors to your computer as you wish.
While you will be limited by the number of USB ports, the NewerTech driver software limits you at 6 additional monitors with Windows and 4 additional monitors with Mac OS X. Not sure many of us home consumers would have desk space for 7 monitors, but in enterprise applications, this could be useful. The adapter can even support resolutions up to 2048 x 1152.
Unfortunately, the software doesn’t have any graphics acceleration, so games are out of the question. The website even says that Keynote, iPhoto and iMovie won’t work with the video adapter. There are also reports that video output via USB (not necessarily this device, just USB video output in general) is often choppy and has considerable lag. If you’re still interested, the NewerTech USB Video Adapter is now shipping, and will cost you $96. Keep in mind that is only 1 adapter, so if you want a theoretical 6 additional monitors, you’ll need to spend $96 x 6.
