Create a high-performance dual-display workstation by connecting a USB Type-C™ device to two independent HDMI® monitors

This USB-C to HDMI MST Hub allows you to connect two HDMI monitors, using a USB-C enabled host device.

Multi-tasking Made Easy

This USB-C to HDMI video splitter connects up to two additional displays in extended or mirror mode. Connecting two independent 4K 60Hz displays creates high-performance workstations, for users in your organization enabling easier multi-tasking resulting in increased productivity.

Multi-Stream Transport (MST) technology combines multiple video signals into a single signal/stream. This MST Hub separates the single stream into two independent signals, one for each HDMI enabled display. Support for High Dynamic Range (HDR) offers increased contrast, brightness, colors, and greater luminosity.

Windows devices that support DP Alt Mode over USB-C feature native support for MST. This USB-C to HDMI hub is compatible with Thunderbolt 4, Thunderbolt 3, and USB4 enabled Windows devices. Plug-and-play installation with no drivers or software required. The 12in (30cm) attached cable provides options for flexible installation configurations, reducing the amount of strain on ports and connectors. Additionally, this dual-monitor splitter is bus-powered, meaning no external power is required.
