I am in possession of the DisplayLink Video adapter.
This is a USB dongle that attaches to a free video port on your system, and extends the display to an additional monitor.
After seeing the flawless movement of a running video using this device during a sumptuous meal arranged by CntrStg and sponsored by DisplayLink at CES 2010 in Las Vegas this January, I am keen to see how it performs with a real life workload.
More soon….
