Plugable TBT4-UDZ (16-in-1 / Thunderbolt 4 / Quad Display / 100W PD) Review
The Plugable TBT4-UDZ is a 16-in-1 Thunderbolt 4 docking station with 100W power delivery and support for up to four 4K60Hz displays on Windows, built to be the single connection point for a fully-loaded desk.
Plugable's TBT4-UDZ goes wider on total port count than anything else in our docking station lineup, 16 ports covering displays, data, storage, and networking, built specifically for users who want to plug in everything and never touch a cable again. Most docks in our catalog top out at two or three displays, the TBT4-UDZ's four-display support on Windows Thunderbolt 4/USB4 systems puts it in a similar tier to Dell's WD22TB4, worth comparing directly if display count is your priority. Two DisplayPort, two HDMI, six USB ports across multiple speeds, SD/microSD card slots, audio, and 2.5Gbps Ethernet cover nearly every peripheral.

Two DisplayPort, two HDMI, six USB ports across multiple speeds, SD/microSD card slots, audio, and 2.5Gbps Ethernet, this is a dock built to be the single connection point for a fully-loaded desk setup.
Comparison to Alternatives
Against our own CalDigit TS4, the TS4 offers similar total port count at a comparable price, the choice largely comes down to specific port mix and brand software preferences. Against our own Dell WD22TB4, both support four displays, the Plugable is cross-platform (Mac and Windows) while the WD22TB4 is optimized specifically for Dell fleet deployments.
