Connect a DVI-equipped display through USB 3.0, while keeping the USB 3.0 port available. The USB32DVIEH USB 3.0 to DVI Adapter turns an available USB 3.0 port into a DVI output port with high resolution 1920x1200 video support. The adapter features a built-in 1-Port USB 3.0 hub, which offers a connection port in place of the USB port used for connecting the DVI adapter - an ideal workaround for Ultrabook or laptop users where only a limited number of USB ports are available. The USB to DVI adapter functions as an external graphics card, providing a convenient way to add multi-monitor capability to a USB 3.0-enabled desktop or laptop computer (optimal performance from USB 3.0, backward compatible with USB 2.0). The included DVI to VGA adapter also allows you to use this device with a VGA display. Leveraging the high-bandwidth (5 Gbps) SuperSpeed USB 3.0 interface, the adapter delivers smooth, high-definition content to your DVI display / projector. The adapter can be used to mirror your primary desktop, showing the same image on each display, or to extend your desktop to double your workspace and increase your productivity.
