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 1.4, one HDMI 2.0, 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. This triple-display capability sets it apart from the CalDigit TS3 Plus and Belkin Thunderbolt 3 Dock Pro, which are limited to dual displays.
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 (216 x 86 x 28 mm), 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.
Pros
- Triple-display support (DisplayPort + HDMI + Thunderbolt 3) - unique among Thunderbolt 3 docks
- 96W charging, the highest available on any Thunderbolt 3 dock
- Good port selection with five USB-A, USB-C 3.1 Gen 2, and TB3 downstream
- Excellent driver support and regular firmware updates from Plugable
- Solid Linux compatibility for non-Windows/macOS users
Cons
- Only 1 gigabit Ethernet at a $259 price point where 2.5/10 GbE is expected
- Larger footprint than competitors due to wedge-shaped chassis
- Thunderbolt 3 only - no Thunderbolt 4 or USB4 future-proofing
- Plastic and metal build rather than full aluminum enclosure
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.
