DisplayPort to DisplayPort Multi-Monitor Splitter 3-Port MST Hub
Product ID: MSTDP123DP
This MST hub lets you connect three monitors to your DisplayPort™ (DP) 1.2 equipped Windows® laptop
or desktop.
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 three additional displays to your computer, which makes multitasking much easier.

Connect to any display
With the MST hub, you can use DisplayPort video adapters and cable adapters that enable you to connect
HDMI, VGA or DVI displays. This ensures your MST hub will be compatible with virtually any television,
monitor or projector. This MST 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 MSTDP123DP will act as splitter, automatically mirroring your video
source across all displays. Resolution limitations apply.
The MSTDP123DP 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.
Average Resolution Bandwidth Allocation
1920x1080 (High-definition 1080p) @60hz - 22%
1920x1200 @60hz - 30%
2560x1440 @60hz - 35%
2560x1600 @60hz - 38%
3840 x 2160 (Ultra HD 4K) @30hz - 38%
Note: Exceeding 100% will reduce functionality.
