Displaylink allows you to connect another monitor from your computer via USB. The cool thing about Displaylink with USB 3.0 is that you can drive a bus powered monitor with no power cord. So essentially you have a bus powered monitor, that is connected only by a USB 3.0 cable to a computer that has a USB 3.0 bus and no other cable. Displaylink has been driving bus powered monitors for a long time but generally not one that supports HD.
Displaylink technology can now be found on a number of monitors in the marketplace. You should always look for the displaylink logo on the packaging or visit the displaylink website for links to a variety of the vendors that support the technology. While USB 3.0 has not had wide deployment yet this is an indication of what will be available in coming months as more computer manufactures get on the USB 3.0 bus.
