Product Features
Technical Overview
This docking station leverages the Thunderbolt 3 host interface to deliver maximum bandwidth for data, video, and power over a single cable. The video subsystem utilizes direct GPU performance without software compression, ensuring minimal latency and maximum image quality for professional applications. The dual display capability functions natively with Thunderbolt or USB4 laptops, with specific support for dual displays on M1, M2, M3 Max/Pro, and M4 Pro/Max MacBooks.
Connectivity extends beyond video with a comprehensive port selection. The dock includes three USB-A ports (two USB 3.2 Gen 1 at 5Gbps and one USB 3.2 Gen 2 at 10Gbps) and two USB-C 3.1 Gen 2 ports (10Gbps), providing high-speed data transfer for storage devices and peripherals. Integrated Gigabit Ethernet with features like MAC Address Pass-through and Wake-on-LAN (WoL) supports secure and manageable network connectivity.
