Mini DisplayPort to HDMI Multi-Monitor Splitter - 3Port MST Hub
Product ID: MSTMDP123HD
This MST hub lets you connect three HDMI monitors to your Mini DisplayPort computer. MST works on any
Windows® device that supports DisplayPort 1.2, such as models of the Lenovo™ Think Pad® and
Microsoft® Surface™. When connected to earlier revisions of DisplayPort, such as DP 1.1 the MST hub
acts as a video splitter.
Increase your productivity with multiple monitors
The newest generations of laptops are more portable than ever, unfortunately this means you’re left with
fewer video outputs and a small integrated screen. The MST hub solves these problems by letting you
connect three independent displays to a single mDP port on your computer, which makes multitasking
much easier. Using the MST hub, you can extend your desktop onto additional monitors and stream
independent content to each display, which makes it easier to multitask and increase your productivity -
perfect for creating an easy-to-dock hot desk solution with a wireless keyboard and mouse peripheral set.
You can also mirror the same image onto multiple displays for remote viewing applications such as digital
signage.

Astonishing picture quality that won’t drain your system resources
MST technology uses your existing video card to minimize the use of system resources while delivering
Ultra HD 4K resolutions. 4K is supported by the latest A/V devices and delivers four times the resolution
of 1080p. Plus, because the MST hub can output high-definition 1080p, the MST hub is perfect for all
high-resolution applications such as graphic design and medical imaging.
The MSTMDP123HD is backed by a 3-year
StarTech.com warranty and free lifetime technical
support.
