Description

StarTech MST14CD123HD Triple HDMI Multi-Monitor Adapter

Overview

The StarTech MST14CD123HD is a bus-powered USB-C Multi-Stream Transport (MST) hub designed to connect up to three independent HDMI displays to a single USB-C port on your host device. This adapter is ideal for workstations requiring expanded desktop real estate for productivity applications, data analysis, or complex monitoring dashboards, leveraging DisplayPort 1.4 Alternate Mode. The MST14CD123HD supports 4K resolution at 60Hz on all three outputs, ensuring crisp visuals without compromising refresh rate. Its compact form factor and bus-powered operation simplify deployment in any workspace.

Compatibility

This MST hub requires a host device with a USB-C port that supports DisplayPort 1.4 Alternate Mode. It is compatible with Windows 10/11 and later versions, and macOS 11 (Big Sur) or later. Specific laptop models from Dell, HP, Lenovo, and Apple are generally compatible, provided their USB-C ports meet the DP Alt Mode 1.4 specification. It is not compatible with devices that only support USB-C data transfer or power delivery without DP Alt Mode. For video conferencing systems or security VMS workstations, ensure the host PC's USB-C port supports DP 1.4 Alt Mode and the operating system is compatible.

Installation Notes

The adapter is bus-powered, drawing power directly from the host USB-C port, eliminating the need for an external power adapter. The integrated cable measures 11.8 inches (30 cm), providing some flexibility in placement. Operating temperature range is 0°C to 40°C (32°F to 104°F). Storage temperature range is -40°C to 70°C (-40°F to 158°F). Maximum operating humidity is 85% RH (non-condensing).
