Universal laptop docking station

The Plugable UD-3900Z adds dual HDMI video outputs, Gigabit Ethernet, a 3.5mm combo audio jack, two USB 3.0 ports and four USB 2.0 ports to a Windows or macOS host. It connects through a single USB 3.0 or USB-C cable and includes both cables in the box. The dock is aimed at office and home productivity setups that need extra screens and peripherals.

Dual 1920x1200 monitors and six USB ports

Two HDMI ports each drive an external display up to 1920x1200, with 1080p also supported. The six USB ports let you attach keyboards, mice, drives and other accessories simultaneously. A 24 W power adapter runs the dock and its downstream ports; the unit does not charge the host computer. Linux is not supported and HDCP-protected content will not play.

Driver install via Windows Update or manual on Mac

Windows 11, 10, 8.x and 7 fetch the DisplayLink driver automatically through Windows Update. macOS 10.14 and later require a manual driver download before the dock works. The dock cannot be mixed with non-DisplayLink USB video adapters and does not accept DisplayPort connections. Buyers who need host charging or Linux support should look elsewhere.

Questions about this item

Will the 24 W power adapter need replacing after heavy use?

The dock ships with a 24 W (12 V, 2 A) external power supply; it has no internal fan or battery, so the adapter is the only part likely to need replacement.

What limits dual-monitor output during long sessions?

Each HDMI port maxes out at 1920x1200, so sustained use is capped at that resolution per display.

How hot or loud does the unit get when left on all day?

The enclosure is passively cooled with no moving parts, so it runs silently and stays warm rather than hot under continuous load.
