Description

Plugable UD-3900C4: Quad Monitor Docking Station for Maximum Productivity

The Plugable UD-3900C4 is the only docking station of its kind—it combines DisplayLink and MST (Multi-Stream Transport) Alt Mode technologies to deliver seamless four-display expansion over USB-C. This TAA-compliant universal docking station drives four extended 1080p displays at 60Hz, with HDMI 1-2 powered by DisplayLink and HDMI 3-4 powered by MST Alt Mode. No other dock offers this hybrid integration, giving you unmatched flexibility for multi-tasking.

Unlock Four Displays on One USB-C Port

Turn your laptop into a powerful command center. Perfect for traders, designers, developers, and anyone who needs multiple screens. The dock supports up to 4 monitors (1080p each) at 60Hz, and also works with fewer displays at higher resolutions when using MST on compatible systems.

Universal and TAA-Compliant

Works with Windows, macOS, and ChromeOS. The DisplayLink driver is required for the first two HDMI ports, while the MST ports work with native driver support on systems with USB-C DP Alt Mode. TAA compliance makes it suitable for government and enterprise deployments.

Power and Connectivity

Provides 96W of power to your laptop via USB-C, plus a full complement of ports: 4 HDMI, 2 USB-A, 1 USB-C, Gigabit Ethernet, audio, and more. Backed by Plugable’s 2-year warranty and expert support.

Frequently Asked Questions

Why does my Mac only show two monitors?

macOS limits DisplayLink to a certain number of displays. The UD-3900C4 supports 2 displays over MST on Macs with native support, but the DisplayLink ports may be limited to one or two depending on your macOS version. Check Plugable's resource page for details.

Can I get faster refresh rates on the MST ports?

Yes, on systems with DisplayPort 1.4 or higher, the MST ports can support 1440p@60Hz or even 4K@30Hz, but the number of active displays may reduce.

Do I need to install drivers?

Drivers are required for the DisplayLink ports. The MST ports work with native drivers on Windows and macOS. Plugable provides easy driver downloads.

Game changer for multi-monitor setup

I was skeptical about driving four monitors from a single USB-C port, but this docking station handles it flawlessly. Setup was a breeze with the DisplayLink drivers, and all four 1080p monitors run at 60Hz without any lag. Perfect for my trading workstation. Highly recommend!

Great for productivity, but driver install required

This dock is fantastic once you get it set up. The picture quality is crisp on all four monitors, and it's great for multitasking. The only downside is that you need to install DisplayLink drivers, and it takes a few minutes to get everything recognized. But after that, it's solid.

Works perfectly with my ThinkPad

I've been using this dock with my ThinkPad for a week now. All four monitors light up instantly, and I love that I can close the lid and still have everything connected. The 4K support is a plus, even though I'm using 1080p. This is a solid investment for anyone needing multiple displays.

Good but requires driver updates

The dock works well, but I had to spend time downloading and updating the DisplayLink drivers. Once that was done, it's been reliable. The USB ports are a bit limited in number, but I manage. Overall, it's a decent product for the price.

Excellent for my MacBook Pro

I was happy to find a dock that works with both my MacBook Pro and my Windows laptop. Setup was smooth, and the DisplayLink software has been stable on macOS. All four monitors are recognized and display at full resolution. This has improved my workflow immensely.

Almost perfect, but one monitor took time

The dock works great overall. I had a slight issue getting one of my monitors to be detected, but after tweaking the DisplayLink settings, it worked. Now I have four monitors running smoothly. The build quality feels solid, and the cable is long enough. Just wish the driver installation was simpler.

Powerful and reliable

I run four 27-inch monitors at 1080p with this dock. It never misses a beat. The passthrough charging is also a nice touch. Setup was quick, and the included instructions were clear. If you need a multi-monitor solution, this is it.

Mixed experience

I've had this dock for two months. It works well for two monitors, but when I added a third, I started getting occasional flickering. The DisplayLink drivers seem to be the culprit. Support was responsive, but I'm not 100% satisfied. Fine if you need just two monitors.

Best docking station I've owned

As a software developer, I need multiple monitors, and this dock delivers. It's plug-and-play after driver install, and I've had zero issues since. The DisplayLink performance is excellent, and the USB ports are convenient for peripherals. Worth every penny.
