AOC, the makers of a range of USB monitors including the16-inch E1649FWU USB monitor, has upped the screen size for its latest USB-powered offering. The new e2251Fwu boasts a 22-inch LED backlit display and receives both power and signal solely through a USB connection. The single USB cable connection is designed to make hooking yourself up with a dual- or multi-monitor setup a simple plug-and-play affair and appeal to those looking to take a second monitor on the road to accompany their laptop.

The e2251Fwu sports Full HD 1920 x 1080 resolution and operates at 60 Hz, with a 5 ms response time, 250 cd/m2 brightness and 20,000,000:1 dynamic contrast ratio. The unit is also HDCP compatible and comes with a built-in USB 2.0 port for daisy-chaining an additional monitor or other USB devices. AOC hasn't provided the full dimensions of the unit but does reveal it measures 10.6 mm (0.41 in) thick. It also comes with a removable stand that AOC says allows it to be used as a digital photo frame or presentation display.

Powered by a DisplayLink chip, the e2251Fwu is compatible with Linux, Windows XP/Vista/7 and OSX Tiger/Leopard/Lion systems. AOC will be showing the monitor at CES 2012, ahead of its release in February priced at US$199.
