A 27-inch 4K business docking display built around a 100W USB-C connection. One cable runs video, a full 4-port USB hub, a gigabit Ethernet passthrough, and enough power to charge most 15-inch laptops. DisplayPort 1.4 input and DisplayPort 1.4 output let you daisy-chain a second 4K monitor off the same laptop. HDMI 2.0 rounds out inputs for a console or desktop tower.
27″ 4K business docking monitor with USB-C 100W, DP 1.4 in/out daisy-chain, HDMI 2.0, RJ-45 Gigabit, and 4-port USB hub.
