This MST (Multi-Stream Transport) hub lets you connect three HDMI monitors to your USB-C(TM) computer. MST ensures hassle-free setup by natively working on any Windows(R) device that supports DP Alt Mode over USB Type-C(TM), such as models of Dell(TM) Precision(TM) and Dell XPS(TM) laptops and ASUS(R) ROG GL752.

Increase your productivity with multiple monitors

The newest generation of laptops are more portable than ever. Unfortunately, this means you're left with fewer video outputs and a small integrated screen. This MST hub solves these problems by letting you connect three displays to a single USB-C 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. This makes it easier to multitask and increase your productivity, which is 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 high-resolution applications such as graphic design and medical imaging.

The MSTCDP123HD is backed by a 2-year StarTech.com warranty and free lifetime technical support.

Note: MST shares 21.6Gbps across all attached displays. Higher resolutions can restrict the available bandwidth with the remaining ports, please see our guidelines 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.
