MST Hub - Mini DisplayPort to 4x DisplayPort
StarTech ID: MSTMDP124DP
This MST hub lets you connect four monitors to your Mini DisplayPort™ (mDP) 1.2 equipped Windows® tablet,
laptop or desktop.
The hub features a newly engineered chipset that was specifically designed and rigorously tested to resolve
compatibility issues with the Microsoft Surface™ Pro 3.
Please note: The surface Pro 3 only supports the use of three displays in total. If more than three external monitors are attached,
the built-in touch screen on your Surface will be disabled. If four monitors are attached, the fourth monitor will not display any
content.
Increase productivity with multiple screens
The newest generations of computers are more portable than ever, which often means that you’re left with fewer
video outputs and smaller integrated screens. This MST hub solves both of these problems by letting you
connect four additional displays to your computer, which makes multitasking much easier.

Connect to any display
With the MST hub, you can use Mini DisplayPort video adapters and cable adapters that enable you to connect
HDMI, VGA or DVI displays. This ensures that your MST hub will be compatible with virtually any television,
monitor or projector. The hub is VESA and DisplayPort certified to support DP 1.2 enabled systems, for
seamless integration with your existing video equipment.
Configure your displays for any environment
Using the MST hub, you can extend your desktop onto additional monitors and stream independent content to

each display, giving you the freedom to multitask and increase your productivity. You can also mirror the same
image onto multiple displays for remote viewing applications such as digital signage.
Enjoy amazing video quality, without draining system resources
MST technology uses your existing video card to minimize the use of system resources while delivering Ultra
HD 4K resolutions. This unprecedented performance makes MST perfect for high-resolution applications such
as graphic design, gaming and medical imaging.
Note: When using a DisplayPort 1.1 video card the MSTMDP123DP will act as a splitter, automatically mirroring your video source across
all displays. Resolution limitations apply.
The MSTMDP124DP supports plug-and-play installation for a hassle-free setup, and is backed by a
StarTech.com 2-year warranty and free lifetime technical support.
Note: MST shares 21.6 Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports,
please see our guideline below for determining an ideal resolution for your setup. Certain graphics adapters have limited MST support and
will only output to three displays in total. If more than three monitors are attached, the fourth will be disabled.
