Lenovo 40A20090UK ThinkPad Ultra Dock (2 USB Ports, 90W AC)
The completely re-designed ThinkPad 90W Ultra Dock comes with an included ThinkPad 90W AC Adapter and grows your capability without having grown in size. The ultimate 90W docking solution, the ThinkPad Ultra Dock includes a wide range of video outputs, including HDMI 1.4, and support for multiple external monitors, so you can multi-task like never before. Note: *ThinkPad Ultra dock is capable to support up to 4k2k(3840x2160)@60Hz via either 1 of 2 DP ports, or support dual 4k2k@30Hz via 2 DP ports. Actual video output on the dock is based on system video performance since the video signal is passing through from system to the Ultra dock. Some of the video ports do have exclusive use and are also dependent on the docked ThinkPad configuration.
