Kensington's universal docking station enables 4K Ultra HD, even when your laptop doesn't have a 4K graphics card. As well as serving as a central hub and charger for all your peripherals, the dock provides Ultra HD to a single 4K monitor or TV via an HDMI or DisplayPort connection. When using two additional monitors instead of one, the dock provides 2K resolution to each screen. There are three available USB 3.0 ports that support high transfer speeds, including one that provides fast charging for a tablet or smartphone. There's also a gigabit Ethernet port so you have a reliable, wired network connection.
