Plugable TBT3-UDZ Review: 8.5/10 - The Triple-Display Thunderbolt Dock
Overview
The Plugable TBT3-UDZ is a Thunderbolt 3 docking station designed for users who need to drive three external displays from a single laptop connection. Priced at $259, it supports triple-display output through one DisplayPort, one HDMI, and one Thunderbolt 3 downstream port. The 96 watts of power delivery can charge even the most power-hungry 16-inch laptops at full speed.
Design and Build
The TBT3-UDZ uses a durable black plastic and metal chassis with a wedge shape that promotes passive cooling through ventilation slots across the top and sides. Measuring 8.5 inches wide, 3.4 inches deep, and 1.1 inches tall, it takes up more desk space than the CalDigit TS3 Plus but offers a lower profile. The front panel includes a 3.5mm headphone jack and USB-A and USB-C ports with fast-charging support.
Display Capabilities
The TBT3-UDZ supports three external displays simultaneously through its DisplayPort 1.4, HDMI 2.0, and Thunderbolt 3 downstream ports. On a supported host like a 2019 MacBook Pro or later, you can run three 4K displays at 60 Hz or a single 5K display plus one additional 4K display. The DisplayPort and HDMI outputs support HDR and FreeSync for a smooth, color-accurate experience across all three monitors.
Charging Performance
The 96 watts of power delivery is the highest available on a Thunderbolt 3 dock, providing enough power to charge a 16-inch MacBook Pro at its maximum 96W charging speed while simultaneously powering all connected peripherals. The dock supports pass-through charging, meaning the laptop’s power adapter is not needed for daily desk use.
Port Selection
Beyond the display outputs and charging, the TBT3-UDZ offers five USB-A 3.0 ports (one with fast charging), one USB-C 3.1 Gen 2 port with 10 Gbps speeds, a 3.5mm headphone/microphone combo jack, and a 1 gigabit Ethernet port. The inclusion of a Thunderbolt 3 downstream port allows daisy-chaining additional Thunderbolt devices such as external SSDs.
Compatibility
The TBT3-UDZ works with Thunderbolt 3 and Thunderbolt 4 hosts on both Windows and macOS. Plugable provides excellent driver support and firmware updates, and the dock has a reputation for stability with fewer disconnect issues than some competitors. Linux compatibility is also solid for users running distributions with Thunderbolt support.
Verdict
The Plugable TBT3-UDZ earns an 8.5 out of 10, delivering exceptional triple-display support and the highest charging wattage available in a Thunderbolt 3 dock. The port selection is good if not class-leading, and the build quality is solid. The 1 gigabit Ethernet instead of 2.5 or 10 gigabit is a noticeable omission at this price point, and the larger footprint is a trade-off for the triple-display capability, but for creative professionals who need three monitors, this is the dock to get.
