Overview

Multi-Tasking Made Easy

Connecting three independent 4K 60Hz displays creates high-performance extended-display workstations. This encourages increased multi-tasking across your organization, resulting in increased productivity.

4K at 60Hz and HDR

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

Hassle-Free Setup

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 3/4, 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 triple-monitor splitter is bus-powered, meaning no external power is required.

This product is backed for 3-years, including free lifetime 24/5 multi-lingual technical assistance.
