Product Features
Technical Overview
This mini dock leverages USB 3.1 Gen 2 technology with a 10 Gbps host connection, supporting simultaneous high-resolution video, fast data transfer, and network connectivity. The video subsystem offers three output options: HDMI or DisplayPort for 4K 60Hz HDR content (when connected to a host supporting DP 1.4 Alt-Mode), or VGA for legacy 1080p displays.
The integrated USB hub provides two USB-A ports and one USB-C downstream port, all operating at 10 Gbps speeds for connecting peripherals, storage devices, and accessories. Gigabit Ethernet ensures stable wired network connectivity in environments where Wi-Fi is unreliable or congested.
