The USB monitor extender uses a USB port on your computer to connect to a high definition DVI or VGA monitor. Connect your desktop or laptop to a DVI monitor and experience the visual impact of 32-bit True Color Depth technology and a sparkling megapixel high definition image. Install the driver and plug the USB 2.0 cable into your Microsoft Windows desktop or laptop computer. The adapter can plug into a LCD or CRT monitor that has a free VGA or DVI port. Standard or wide screen viewing modes are supported. Clone your monitor image onto 7 monitors or display a single viewing field over multiple screens.
