Expand your desk with a true 14-in-1 USB-C dock

Turn a single connection into a versatile workstation. The Plugable UD-3900C4 blends robust power with multi-display capability, making it ideal for busy offices, home studios, or shared hot desks. Its compact enclosure hides a full set of ports that keep your peripherals at arm’s reach while you work.

Whether you’re tracking analytics, editing content, or coordinating projects across several apps, this docking station aims to streamline your setup without adding clutter. The design prioritizes practical convenience and dependable performance, so you can focus on the task at hand rather than hunting for ports.

Quad-monitor clarity and power

Four HDMI outputs support 1080p at 60Hz, giving you a generous canvas for data dashboards, design references, and collaboration windows. The dock also powers your laptop with up to 96W charging while you work, so you don’t have to juggle adapters or swap plugs mid-project. A dedicated USB-C port (20W) handles data transfer and extra charging for accessories like keyboards or earbuds.

• 4x HDMI outputs for expansive multi-monitor layouts
• Up to 96W laptop charging to keep your workstation energized
• 4x USB 3.0 ports (5Gbps) for fast peripheral data
• 1x USB-C port (5Gbps) with 20W charging for extra devices
• Ethernet, SD Card Reader, and audio in/out for complete desk ecosystems

Smart, flexible display technology

Hybrid Display technology combines DisplayLink and DisplayPort Alt Mode MST to enable four extended displays. HDMI 1–2 rely on DisplayLink, while HDMI 3–4 use Alt Mode. A compatible USB-C port with DisplayPort Alt Mode MST is required for HDMI 3 and 4 to function, delivering flexible layouts across different systems.

• Supports USB4, Thunderbolt 3/4, and USB-C systems with DisplayPort Alt Mode MST
• Up to four monitors on Windows 10+ and ChromeOS 100+
• macOS supports up to three extended displays; the fourth may mirror due to MST limitations

Compatibility and reliability

This dock is designed to work with a broad range of environments, including corporate IT setups where drivers may be updated automatically. In many cases, DisplayLink drivers install via Windows Update; some networks may require manual installation. Plugable offers two years of coverage and lifetime support from a North American team to help with questions before and after purchase.

Ideal use cases

Finance analysts, engineers, and media teams can transform hot desks or fixed workstations into productive hubs with multiple displays and steady peripheral connectivity. The blend of 4K-friendly (where supported by your hardware) and 1080p displays, plus fast USB data rates, supports a wide range of workflows without requiring a different setup for every project.

Note that performance depends on your computer’s capabilities and display configuration. This description highlights capabilities and typical outcomes rather than guarantees, giving you practical expectations for real-world usage.
