USB Displaylink adapters have been around for a while, but it seems most people just ignore them due to their poor performance and low resolution. Well Logitech has sounded the battle cry and released a new DisplayLink adapter capable of QWXGA resolution (2045×1152)! Available for PC and Mac, desktop and Laptops, it could be a great addon for anyone looking to add an extra display to your system.
Available from GeekStuff4U for approximately $140.
