Manufacturer description
The Plugable USB C Triple Display Docking Station turns a single USB-C port into a 12-in-1 workstation hub, and it does it on machines that normally refuse to drive more than one external screen. Connect up to three HDMI monitors at once: one 4K display at 30Hz through native USB-C Alt Mode, plus two 1080p panels at 60Hz driven by integrated DisplayLink graphics. That DisplayLink layer is what lets this Plugable dock bypass the single-display ceiling on Apple Silicon MacBooks, including M1, M2, M3, M4 and M5 systems. Around the video outputs you get six USB 5Gbps ports for peripherals, wired…
SpecPicks Verdict
SpecPicks scored Plugable USB C Triple Display Docking Station using a rating × review-volume × price-fit model applied to published specs and reviews across the gaming monitors category. Plugable's gaming monitors lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Frequently Asked Questions
Will this dock run three monitors on a MacBook with an M1 or M2 chip?
Yes. Apple Silicon MacBooks natively support only one external display, and this dock bypasses that using DisplayLink graphics for two of the three HDMI outputs. Plugable lists compatibility with M1, M2, M3, and newer M4 and M5 systems. You must install the DisplayLink driver on macOS 11 or later first.
What resolution and refresh rate does each of the three HDMI ports support?
One HDMI port runs a single 4K display at 30Hz through native USB-C Alt Mode. The other two run 1080p at 60Hz each through DisplayLink. The 30Hz ceiling on the 4K port means it suits documents, dashboards, and spreadsheets rather than video or gaming.
Does it charge my laptop while everything is connected?
Yes. The dock delivers up to 100W of USB-C Power Delivery to the host system, so a single cable handles video, data, Ethernet, and charging at the same time. Confirm your laptop's own charging requirement does not exceed 100W.
Does this work with Linux?
No. Plugable states the dock is not compatible with Linux. Supported platforms are Windows, macOS 11 and later with driver installation, and ChromeOS v100 and later. HDCP is also not supported, which can block DRM-protected video playback.
What ports do I get besides the three HDMI outputs?
The dock is a 12-in-1 design with six USB 5Gbps (USB 3.0) ports for peripherals, wired Gigabit Ethernet, an audio connection, and USB-C Power Delivery for host charging. It connects to USB-C, USB4, or Thunderbolt host ports.
