The Thunderbolt Certified 16-in-1 Quad docking station from Plugable delivers peak performance. The innovation starts with our display connections. Connect your 4K screens through 2x HDMI ports and 2x DisplayPort ports — a rare level of display flexibility in a Thunderbolt dock. But the real expansion picks up at the ports.

Quad Display With this Thunderbolt 4 docking station Windows computers can use the 2x HDMI ports, and 2x DisplayPort ports to connect as many as 4x screens at up to 4K 60Hz.

On Mac (Intel, M1 / M2 / M3 Pro/Max, M4 / Pro/Max, M5 / Pro/Max CPU), extend your desktop to 2x screens using any combination of HDMI and/or DisplayPort. Macs with an M1 / M2 / M3 CPU only support one external display. 100W Power Delivery The laptop Thunderbolt docking station offers USB Power Delivery up to 100W (98W certified) — no more climbing under the desk to get plugged in. Not all laptop docking stations handle power the same. With the TBT4-UDZ, if your laptop needs less power, the docking station adjusts and only sends the optimal wattage. And with 6x available USB ports, and one USB-C port, your devices will always have a place to connect. Compatibility The TBT4-UDZ is compatible with *Windows 10 and later and **macOS 11+. Actual number of screens that can be extended depends on capabilities of the host computer. Be sure to see the Display Compatibility Chart below. *On some Windows laptops, enabling four displays may require a Windows settings change to disable the internal screen. **On Macs, additional monitors beyond specs below may not function, and/or will “mirror” rather than extend.
