Universal laptop dock for dual monitors

The Plugable UD-3900H turns a single USB 3.0 connection into two video outputs, Gigabit Ethernet, audio jacks and six USB ports. It sits horizontally on the desk and works with Windows 7 through 11 or macOS 10.14 and later. Linux is not supported and the dock does not charge the host computer.

Dual video at 1920x1200

Each monitor runs at up to 1920x1200 resolution at 60 Hz using the built-in HDMI and DVI ports; a DVI-to-VGA and a DVI-to-HDMI adapter are included. A single HDMI display can reach 2560x1440 at 50 Hz. The dock does not support HDCP, so encrypted or copy-protected content will not play back.

Steady throughput for productivity

SuperSpeed USB 3.0 delivers up to 5 Gbps between the laptop and the dock's two USB 3.0 ports, keeping file transfers and peripheral traffic stable during long work sessions. The dock is intended for web and office applications, not for gaming, and cannot be mixed with non-DisplayLink USB video adapters.

Questions about this item

What does the 1920x1200 at 60Hz figure mean when I connect two monitors to the dock?

Each of the two video outputs — HDMI and DVI — can drive a display at 1920x1200 resolution with a 60Hz refresh rate simultaneously, giving you a dual-monitor workspace at full HD quality.

The dock uses a USB 3.0 host link; what does that cap in practice?

The USB 3.0 connection limits total bandwidth to 5 gigabits per second shared across video, Ethernet, audio and all six USB ports, so heavy simultaneous transfers will contend for that pipe.

What does the horizontal UD-3900H need to sit on my desk?

The unit lays flat in a horizontal orientation and connects to the host with a single included USB 3.0 or USB-C cable; no mounting hardware or special brackets are required.
