8-in-1 USB-C Dual HDMI Adapter with 4K 60Hz MST Video, 2-Port USB 3.2 Hub, Gigabit Ethernet, SD/MicroSD Card Reader, and 100W PD Pass-Through for Laptops and Workstations
The StarTech 120B-USBC-MULTIPORT is a dual HDMI adapter that drives two independent 4K 60Hz HDMI displays from a single USB-C connection through MST (Multi-Stream Transport) via DP 1.4 Alt Mode with DSC, using the host laptop's GPU for uncompressed video with minimal CPU usage. The bus-powered adapter provides dual HDMI 2.0b outputs with HDR, two USB 3.2 Gen 1 (5Gbps) USB-A ports with BC 1.2 charging, SD and MicroSD card readers, Gigabit Ethernet, and 100W USB PD 3.0 pass-through for laptop charging. An 8-in-1 dual HDMI adapter from StarTech with 12-inch host cable, StarTech Connectivity Tools, and a 3-year warranty.
The dual 4K 60Hz output requires a host with DP 1.4 and DSC support (Intel 11th Gen or later recommended), with DP 1.2 hosts supporting dual 4K at 30Hz. The 100W PD pass-through port delivers up to 85W for laptop charging with 15W reserved for stable adapter operation, and the BC 1.2 port provides 7.5W fast charging for smartphones and USB peripherals.
