Universal docking station

The Plugable UD-3900 adds ten ports through one hybrid USB 3.0 or USB-C cable. It suits Windows, macOS and ChromeOS laptops or desktops that need extra displays, wired networking and more USB connections without opening the case.

Dual video and adapter flexibility

One HDMI port and one DVI-I port drive two monitors up to 1920x1200 at 60 Hz. The boxed HDMI and VGA adapters let the second output match HDMI, DVI or VGA screens. A single HDMI display can reach 2560x1440 at 50 Hz when used alone.

Wired connectivity and daily layout

Gigabit Ethernet, 3.5 mm audio jacks, two USB 3.0 ports and four USB 2.0 ports sit on a compact chassis. The dock draws power from the host and does not charge the laptop. It is not suited for gaming, HDCP playback or mixing with non-DisplayLink graphics adapters.

Questions about this item

Will the DisplayLink driver software need regular updates after I set it up?

Windows 11, 10, 8.1, 8 and 7 drivers can be automatically installed by Windows Update when an internet connection is present. macOS 10.14 or later requires manual driver installation from the Plugable website.

What resolution ceiling hits first when I run two external monitors all day?

Dual HDMI displays are supported up to 1920x1200 @ 60 Hz. A single HDMI monitor can reach 2560x1440 @ 50 Hz, but 1440p is not available when using the included HDMI-to-DVI adapter or a DVI monitor.

How warm does the aluminium chassis get and does the fan spin up under a full 10-port load?

The dock has no fan and draws power from the host USB 3.0 or USB-C port, so it runs silently. Typical warmth is noticeable only when all six USB ports, Gigabit Ethernet and dual video are active for extended periods.
