If you've ever been interested in the DisplayLink technology--which allows you to daisy-chain up to six monitors to one system via USB--but you don't actually own a Displaylink monitor, you're in luck.
This week Diamond Multimedia introduced its first DisplayLink-enabled USB graphics adapter, the BVU160. The adapter supports VGA, DVI, and resolutions up to 1600x1200 and 1680x1050.
Once connected, your monitor will behave as if it is DisplayLink-enabled and you'll be able to add an additional monitor simply via USB. It's unclear as of now if you'll need additional adapters to add additional monitors.
The adapter will be available at the end of February on Diamond's Web site at a price TBD.
