Description

Plugable UD-3900PDZ (B-Stock) Triple Monitor USB-C Dock

The Plugable UD-3900PDZ is a universal USB-C docking station designed for enterprise, remote, and hybrid work. This B-stock unit comes at a reduced price while offering the same core functionality: connect up to three HDMI displays, deliver 100W of power to your laptop, and plug in six USB 3.0 devices all through one USB-C cable. It's an ideal solution for professionals who need a versatile, high-capacity dock without the premium cost.

Is a B-Stock Dock Right for You?

B-stock units may have minor cosmetic blemishes or repackaged packaging, but they are fully tested and functional. Each unit is covered under Plugable's standard warranty, so you can buy with confidence. If you're looking for a cost-effective way to equip a multi-monitor workstation, the UD-3900PDZ B-stock is a smart choice.

Maximize Productivity with Triple Displays

With three HDMI outputs, you can extend your desktop across three monitors—perfect for spreadsheet-heavy tasks, data analysis, or programming. The dock also features Gigabit Ethernet for fast wired networking, and six USB 3.0 ports to connect your keyboard, mouse, external drives, and more. The 100W power delivery ensures even power-hungry laptops stay charged.

What to Consider When Buying a B-Stock Dock

While B-stock offers savings, be sure to verify the warranty period and return policy. Plugable provides a two-year warranty on all docks, including b-stock items, so you're protected. If you prefer a brand-new unit, consider the standard UD-3900PDZ, which is also available.

Great value for B-stock

I couldn't tell it was refurbished. Works perfectly with my triple monitor setup. The 100W charging is a big plus. Minor cosmetic scuff, but that's why it's cheaper.

Works, but had to troubleshoot

Initially the display ports didn't all work, but after updating firmware it works fine. B-stock means some marks, but functionality is there. Would have preferred a new one, but for the price, it's okay.

Excellent triple monitor dock

I drive three 1080p monitors plus my laptop screen. Everything runs smoothly. The 100W charging is plenty for my Lenovo ThinkPad. Setup was easy with Plugable's drivers.

Solid dock, but port placement

The dock works great, but the ports are all in the back, which my clutter doesn't like. However, for the price and performance, it's a winner.

It's okay

Does the job, but I had some flickering on one monitor. Not sure if it's the dock or my cable. It's a B-stock, so maybe it's a slight defect. Still usable.

Best dock for MacBook Pro

Works perfectly with my MacBook Pro (Intel). Three monitors plus charging in one cable. The B-stock condition was excellent, no visible issues. Would buy again.
