If your computer is lacking the necessary video port to marry up with the new display you desire, Gefen has just made it easy for you with a “USB to DVI HD” adapter. The adapter offers plug and play connectivity for any digital display using the DVI, VGA or HDMI format, with support for resolutions up to 1920×1200, 1080p and 2k.
Users have the option to select an extended desktop or have the USB-connected display mirror the main display’s content. Multiple adapters can also be connected to the same computer system, including six USB to DVI HDs for a PC and four USB to DVI HDs for a Mac.
List price on the Gefen site is $129
