Product Info

USB Type-C to 3 Port DisplayPort MST Hub

This MST hub lets you connect three DisplayPort monitors to your USB Type-C computer. MST ensures hassle-free setup by natively working on any Windows® device that supports DP alt mode over USB Type-C, such as models of Dell Precision™, Dell XPS™ laptops and ASUS® ROG GL752.

The MST hub also works with Thunderbolt™ 3 ports to provide Thunderbolt 3 to triple DisplayPort conversion. Plus with a lower price point than docks, MST offers a multi-monitor solution that’s more cost-effective than a traditional laptop docking station.

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. 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.

Increase Productivity with multiple screens

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.

Works with any monitor, television or projector

With this MST hub, you can use separate DP video adapters to connect HDMI, VGA or DVI displays, for compatibility with all of your existing monitors
