From the leader in desktop productivity solutions, Kensington’s SD4000 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 (3840x2160) 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 (2048x1152). There are three available USB 3.0 ports that support transfer speeds of up to 5Gbps, including one that provides 2.1 AMP fast charging for a tablet or smartphone. There’s also a gigabit Ethernet port so you have a reliable, wired network connection.FEATURES & BENEFITSBest For: USB 3.0 Laptops, Ultrabooks & Windows Tablets and Monitors that support up to 4KConnection Technology: USB 3.0 (DisplayLink)Compatibility: Windows 7 or above, macOS 10.14# of Monitors Supported: 2Video Ports: 1 x HDMI v1.4 or 1 x DisplayPort v1.1 and 1 x DVI-I (DVI-to-VGA adapter is NOT included)Maximum Resolution Supported: Single Monitor: 3840 x 2160 @ 30Hz and Dual Monitors: 2048 x 1152 @ 30HzDisplayLink driver installation required.
