The USB to HDMI adapter serves as an external graphics card and is a convenient way to add multi-monitor functionality to a USB 3.0-capable desktop computer or laptop (optimal performance with USB 3.0, backward compatible with USB 2.0). To save space while traveling, this ultra-portable USB to HDMI adapter takes up very little room, is very lightweight, and easily fits into a laptop bag. The adapter utilizes the high bandwidth (5 Gbps) of the SuperSpeed USB 3.0 interface and seamlessly delivers high-definition content to your HDMI display or projector. The adapter can be used to mirror the primary desktop, display the same image on each screen, or extend the desktop to double your workspace and increase productivity. Compatibility for Windows.
