NewerTech announced today the NewerTech USB Video Display Adapter for adding an additional HDMI, DVI, or VGA display with up to 2048 x 1152 resolution via any Mac or PC computer’s standard USB 2.0 port.

This bus-powered adapter enables cloning and extended desktop modes, although you need to hook up the supplied secondary adapter if you want to connect VGA and HDMI monitors. The product does not allow OpenGL acceleration, so applications that require Quartz Extreme, Quartz Composer or other related frameworks are not fully supported

Additionally, the adapter requires at least Mac OS X 10.4.11, or Windows 2000 SP4/XP SP2. You can purchase the NewerTech USB 2.0 display adapter for only $95.99 each
