3-Port USB-C to DisplayPort MST Hub - 4K 30Hz
Product ID: MSTCDP123DP
This 3-port USB-C to DisplayPort MST hub lets you connect three DisplayPort monitors to your USB Type-
C Windows device, conveniently helping you to maximize your productivity.
Multitasking Made Easy
With devices becoming more portable than ever, you can be limited to fewer video outputs and confined
to your small integrated screen. This MST hub solves that problem by enabling you to connect
three displays to your USB-C computer, making multi-tasking much easier.
Using this USB-C to DisplayPort splitter, you can mirror your display onto additional monitors or stream
independent content to each display, which makes it the ideal accessory for travel or hot-desking.

Astonishing Picture Quality
Multi-Stream Transport (MST) technology uses your existing video card to minimize the use of system
resources while delivering UHD 4K resolutions for up to two monitors simultaneously. Plus, because
the multi-monitor splitter can output HD 1080p on three independent displays, it’s perfect for all high-
resolution applications such as graphic design and medical imaging.
Hassle-Free Setup
MST offers an easy setup, by natively working on any Windows device that supports DP Alt Mode over
USB Type-C. This USB-C multi-monitor adapter is Thunderbolt 3 compatible and offers plug-and-
play installation with no drivers or software required. Additionally, this DP MST hub is powered by the
USB-C port, meaning no external power cords are necessary.
