14-in-1 Dock with 4x HDMI

The Plugable UD-3900C4 is a universal docking station built for professionals who need to drive four external monitors from a single laptop connection. It suits Windows 10 or later and ChromeOS 100 or later users with compatible USB4 or Thunderbolt 3/4 ports. It is not recommended for macOS. Buyers who need native macOS support or more than four displays should look elsewhere.

Display Limits and Interface Constraints

The dock delivers up to four 1080p displays at 60 Hz using a combination of DisplayLink technology and Multi-Stream Transport. Full quad-display performance requires a host port that supports the necessary bandwidth and alt modes; older USB-C ports without video alt mode will not drive the monitors. The single USB-C upstream connection carries both video and data, so total throughput is shared across all active displays and peripherals.

Ports, Power and Practical Headroom

Four HDMI outputs, four USB 3.0 ports at 5 Gbps, one USB-C port at 5 Gbps with 20 W charging, Gigabit Ethernet, SD card reader and 3.5 mm audio in/out provide broad peripheral connectivity. The dock supplies up to 96 W of laptop charging, certified at that level, letting most thin-and-light notebooks run without their own adapter. Systems demanding more than 96 W or needing Thunderbolt-speed downstream ports will exceed what this unit can provide.
