Overview
This 3-port USB-C to DisplayPort MST hub lets you connect three DisplayPort monitors to your USB Type-C Windows device, conveniently helping you to maximize your productivity.
Multitasking Made Easy
With devices becoming more portable than ever, you can be limited to fewer video outputs and confined to your small integrated screen. This MST hub solves that problem by enabling you to connect three displays to your USB-C computer, making multi-tasking much easier.
Using this USB-C to DisplayPort splitter, you can mirror your display onto additional monitors or stream independent content to each display, which makes it the ideal accessory for travel or hot-desking.
Astonishing Picture Quality
Multi-Stream Transport (MST) technology uses your existing video card to minimize the use of system resources while delivering UHD 4K resolutions for up to two monitors simultaneously. Plus, because the multi-monitor splitter can output HD 1080p on three independent displays, it's perfect for all high-resolution applications such as graphic design and medical imaging.
Hassle-Free Setup
MST offers an easy setup, by natively working on any Windows device that supports DP Alt Mode over USB Type-C. This USB-C multi-monitor adapter is Thunderbolt 3 compatible and offers plug-and-play installation with no drivers or software required. Additionally, this DP MST hub is powered by the USB-C port, meaning no external power cords are necessary.
- MULTI-MONITOR CONFIGURATION: USB Type-C to Triple DisplayPort adapter/splitter hub drives up to three 1080p 60Hz or two 4K 30Hz displays using a USB-C DP Alt-Mode port on Windows laptops; TB3/TB4/USB4 Compatible; Not compatible with macOS
- NO DRIVERS OR SOFTWARE: Increase productivity by adding three extended or mirrored displays to a Windows laptop; Utilize integrated or discrete GPU (Intel/AMD/Nvidia) capabilities enabling high performance graphics with minimal CPU usage
- HARDWARE COMPATIBILITY: Host system must support DP Alt Mode 1.2 / HBR2 / MST; Please verify maximum number of displays supported by your GPU; Some GPU chips (such as Intel HD Graphics) are only capable of supporting a maximum of three displays
- EXTRA LONG CABLE: 1ft (30 cm) built-in cable for extended reach reduces port/connector strain on 2-in-1 devices like Surface Pro 7, HP Elite x2/laptops on riser stands; Ideal for on-the-go travel use in office/home office/shared workspaces
- OUR ADVANTAGE: Included connectivity tools for IT Pro's and IT help-desk support teams with Windows Layout Utility which restores windows app locations when re-connecting the USBC to Triple DisplayPort Adapter
