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. Offering sixteen total ports to park your peripherals, including 7x USB ports, SD and microSD card readers, Audio, and 2.5Gbps Ethernet. It even adapts to your desk with an included stand for vertical or horizontal orientation options. 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. Can also be used a single, dual, or triple display docking station. 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.
