The USB32HDEH USB 3.0 to HDMI Adapter is TAA compliant and turns a USB 3.0 port into an HDMI output port with 1920x1200/1080p video support. The adapter features built-in USB 3.0 pass-through, which offers a connection port in place of the USB port used for connecting the HDMI adapter - an ideal workaround for Ultrabook or laptop users, where only a limited number of USB ports are available.Functioning as an external graphics card, this USB to HDMI adapter provides 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).Leveraging the high-bandwidth (5 Gbps) SuperSpeed USB 3.0 interface, the adapter delivers smooth, high-definition content to your HDMI 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. The included HDMI to DVI adapter also allows you to use this device with a DVI display.
