Dimension Scores
The dock's 100W Power Delivery and single-cable connectivity reduce desktop clutter, supporting a more organized workspace.

The unit is primarily constructed from plastic, which some users noted as less premium, though it is not frequently moved.
The design is functional and understated, fitting into most office environments without drawing attention, but it lacks any distinctive visual features.

What Buyers Say
Many users highlight this Plugable dock as a lifesaver for managing multiple peripherals and displays with a single USB-C connection, especially for Mac users who are typically limited to one external monitor. The 100W Power Delivery is a frequently praised feature, keeping laptops charged throughout the day. However, the requirement for DisplayLink drivers on macOS and the lack of HDCP support for streaming protected content are recurring points of frustration. Users also point out the limitation of only one 4K 30Hz display, with the other two being 1080p 60Hz.
“Dude, this thing actually let me use three monitors with my M1 MacBook, which is wild, but seriously, no Netflix on the big screen is a bummer, and getting the Mac drivers working was a bit of a dance.”

Frequently Asked Questions
Does this docking station work with Apple M1/M2/M3 MacBooks for triple displays?
Yes, this docking station uses DisplayLink technology to bypass the native single-display limitation of Apple M1/M2/M3 MacBooks, allowing you to connect up to three external HDMI displays.
Do I need to install drivers for this docking station?
For Windows and ChromeOS, driver installation is typically automatic. However, for macOS (11+), you will need to manually install the DisplayLink Manager software for full functionality.
Can I watch Netflix or other streaming services on monitors connected to this dock?
No, this docking station does not support HDCP (High-bandwidth Digital Content Protection), which means you cannot play protected content from streaming services like Netflix or Hulu on the connected displays.
What are the maximum resolutions and refresh rates for the displays?
One HDMI port supports up to 4K at 30Hz via Alt Mode, while the other two HDMI ports support up to 1080p (or 1920x1200) at 60Hz via DisplayLink.
Does this dock charge my laptop?
Yes, the docking station provides up to 100W of Power Delivery to your host laptop through the USB-C connection, allowing it to charge while connected.
Buying Guide
When you're looking at docking stations, you need to think about what you're actually plugging in. Don't just count ports; consider the resolution and refresh rate you need for each monitor, and whether your laptop can even handle it. Also, check if you need to stream protected content, because not all docks support that. Finally, driver requirements, especially for Macs, can be a hidden step.
100W Power Delivery (PD)
This means the dock can charge your laptop with up to 100 watts of power through the same USB-C cable that connects it to the dock. It's like having your laptop charger built right into the dock, so you only need one cable to power and connect everything.
DisplayLink Technology
DisplayLink is a type of graphics technology that lets you connect more monitors than your computer's built-in video outputs usually allow, especially useful for MacBooks with limited native display support. Think of it as a virtual graphics card that sends video over USB, but it does require a software driver.
USB-C Alt Mode (Alternate Mode)
This is a feature of USB-C that allows the port to carry non-USB signals, like video (DisplayPort Alt Mode). It's how one of the HDMI ports on this dock can directly output video from your laptop's graphics card without needing DisplayLink drivers, offering a more direct and often higher-performance connection.
Alternatives
If this dock doesn't fit, look for docking stations with Thunderbolt 4 or USB4 for higher bandwidth and multiple 4K 60Hz display support, or docks that explicitly list HDCP support if streaming protected content is a priority.
