HIS Multi-View+Sound Adapter Review
 

The Multi-View + Sound Adapter from HIS is a device suited for the USB 3.0 bus, meant to connect an additional monitor to our system, on the HDMI interface; the product does not need extra power and functions with the help of the DisplayLink technology. The manufacturer also mentions that we can connect up to 6 displays to a single system, each with its own adapter.
