The Lenovo ThinkPad Universal Thunderbolt 4 Dock is a business-grade Thunderbolt 4 dock delivering 100W of charging and supporting up to four simultaneous displays — an unusually high display count for a single-cable dock. It achieves this via two DisplayPort 1.4 outputs, one HDMI port, and one downstream Thunderbolt 4 port that can drive a fourth display via daisy chain. The four downstream USB-A 3.2 Gen 2 (10 Gbps) ports are faster than the Gen 1 ports found on many competing docks. Note: some retailers list the HDMI as 1.4 while others list 2.1 — confirm with the official Lenovo datasheet for your specific unit.
Lenovo’s TB4 business dock with 100W PD, 4-display support (2x DP 1.4, 1x HDMI, 1x TB4), 4x USB-A Gen 2, and Gigabit Ethernet.
