StarTech MSTCDP122DP USB-C DP Multi Monitor Adapter
Overview
The StarTech MSTCDP122DP is a USB-C Multi-Stream Transport (MST) hub designed to expand a single USB-C port into two DisplayPort outputs. This allows you to connect two independent monitors to a compatible laptop or workstation, significantly increasing screen real estate for productivity tasks. It's ideal for scenarios where a compact, bus-powered adapter is needed to drive multiple displays from a single USB-C source, such as a portable workstation or a docking station setup.
Compatibility
This MST hub requires a USB-C port that supports DisplayPort Alternate Mode (DP Alt Mode) 1.2 or higher, along with Multi-Stream Transport (MST). It is compatible with Thunderbolt 3, Thunderbolt 4, and USB4 ports. The adapter operates with Windows operating systems. It supports DisplayPort 1.2 HBR2 signaling for its dual 3840x2160 @ 30Hz outputs.
Installation Notes
The MSTCDP122DP is powered directly from the USB-C host port, eliminating the need for an external power adapter. The integrated cable measures 12.8 inches (32.5 cm) in length. Operating temperature range is 5°C to 35°C (41°F to 95°F).
