Universal USB-C Dock for ThinkPad

The Lenovo ThinkPad USB-C UltraDock provides a single-cable connection for compatible ThinkPad laptops including the X1 Carbon 5th Gen, T470, T470s, X270 and Yoga 370. It adds wired networking, audio and multiple peripherals through one USB-C port while delivering up to 60W of charging power. The 90W AC adapter is included.

Video capacity and headroom

The dock drives a single UHD display at 30Hz or two FHD screens simultaneously, covering typical dual-monitor office layouts. Higher refresh rates or additional displays beyond two are not supported, so users needing triple-head or high-frame-rate setups will need a different solution.

Build and daily connectivity

Three USB 3.0 ports, two USB 2.0 ports and one USB-C port give ample bandwidth for keyboards, mice and external drives. A Gigabit Ethernet jack ensures stable wired networking and a 3.5mm combo jack handles headsets. The fixed 2-prong power cable keeps the desktop tidy but limits placement to outlets within its reach.

How can I verify that the dock is delivering video to two FHD monitors at the same time?
