8-in-1 USB-C Docking Station

This Belkin docking station expands a laptop's connectivity through a single USB-C cable. It provides dual 4K 60Hz HDMI ports, a 4K 120Hz DisplayPort, two USB-A 3.0 ports, two USB-C data ports, and a 100W Power Delivery charging port. It is designed for professionals who need a multi-monitor workstation and high-speed peripheral access.

Triple Display Output and 100W Charging

The dock supports MST technology on Windows to extend across three external monitors plus the laptop screen, delivering 4K at 120Hz via DisplayPort and 4K at 60Hz via HDMI. The 100W PD port charges the host laptop while all ports are active, and the USB-A and USB-C data ports operate at 5Gbps for fast file transfers. An aluminum alloy casing aids heat dissipation during sustained loads.

For Multi-Monitor Windows Users Needing High

This suits users with Windows laptops that support DisplayPort Alt Mode and Power Delivery over USB-C, who want three extended 4K displays including a high-refresh panel. It is not for macOS users who require extended desktop mode across multiple external screens, as macOS only supports mirror mode over MST. Buyers whose laptops lack DP Alt Mode or sufficient USB-C power delivery should verify compatibility before purchase.
