Description

The StarTech.com USB C Multiport Adapter DKT31CSDHPD3 converts a single USB-C or Thunderbolt 3/4 port into a workstation-ready hub with 4K 60Hz HDMI video, two USB 3.1 Gen 2 Type-A ports (10Gbps), an SD/microSD card reader, Gigabit Ethernet and 100W USB Power Delivery pass-through. It includes an attached 10-inch (25 cm) host cable and supports DP Alt Mode (DP 1.4 for up to 4K 60Hz; DP 1.2 up to 4K 30Hz).
