Product Description
This USB-C™ Multiport Adapter/Docking Station with DisplayPort™ 1.4 (Alt Mode) and Multi-Stream Transport (MST), features three video output options (HDMI, VGA and USB-C video) to support a single or multi-monitor workstation. The USB-C video port supports USB 3.2 Gen 2 (10Gbps) with 10W of power, to connect a USB-C monitor or a USB-C peripheral. In addition, the Docking Station also features a 2-Port USB-A 3.2 Gen 2 (10 Gbps) Hub, a Gigabit Ethernet port, and providing advanced charging through a USB Power Delivery (PD) 3.0 pass-through port. The Multiport Adapter connects to a laptop's USB-C or Thunderbolt 3/4™ port, using the integrated 10-inch (25.4cm) USB-C cable.

Versatile, High-Performance Video via MST

The compact USB Type-C Docking Station features three video output options to turn your laptop into a single or multi-monitor workstation.

HDMI Port Provides HDR video with resolutions up to 4K 60Hz.

VGA Port Provides analog video with resolutions up to 1080p 60Hz.

USB-C Port Provides the industry's first downstream full featured video or data (10Gbps) USB-C port that supports DP Alt Mode video or peripheral connection, on a non-Thunderbolt adapter.

The advanced video versatility of this Multiport Adapter, makes it suitable for a wide variety of applications:

  • Connect a portable USB-C monitor as an extended display, to obtain a high resolution external monitor during on-the-go travel between an office desk, home office, hot desk, or the boardroom.
  • Connect a USB-C peripheral to the downstream 10Gbps USB-C port, while using the HDMI and/or VGA ports to connect external monitor(s) as extended display(s).
  • Connect multiple external monitors as extended displays, using any combination of the two video ports, to create a high-productivity workstation. USB-C video adapters (sold separately) can be used to connect HDMI, DVI, VGA, or DisplayPort monitors to the USB-C video port.

This Docking Station utilizes MST to obtain video versatility. Video performance is based upon the number of attached monitors and the host computer's video controller. Consult the manufacturer of the host computer to determine MST video performance. StarTech.com performs rigorous performance benchmarks with all major host computer video controllers.
