10-in-1 USB-C Docking Station

The Wavlink WL-UMD325 adds dual HDMI video, Gigabit Ethernet, USB data ports, card readers and audio to a laptop through a single USB-C connection. It is built for professionals who need a compact hub to run two external monitors while keeping the host charged. The silver aluminium housing aids heat dissipation during sustained workloads.

Dual 4K Output Requires Host DP 1.4 with DSC

Windows laptops must provide DisplayPort 1.4 with DSC over their USB-C port to drive two 4K displays at 60 Hz; DP 1.4 without DSC drops to dual 1440p at 60 Hz, while DP 1.2 is limited to dual 1080p at 60 Hz. macOS systems mirror both external monitors at 4K 60 Hz when the host supports DP 1.4, otherwise they fall back to 30 Hz. The hub itself cannot exceed the host's native video capability.

Upgrades Single-Port Laptops Lacking Video

This dock replaces a basic USB-C adapter by adding 85 W pass-through charging, two 5 Gbps USB-C ports, one 5 Gbps USB-A port, SD and Micro SD slots at 104 MB/s, and a 3.5 mm audio jack. The jump is worthwhile when a user needs simultaneous dual-monitor expansion, wired networking and laptop charging from one cable. It does not suit buyers whose USB-C port lacks video alt-mode or Power Delivery support.

Questions about this item

Which USB-C port on the WL-UMD325 provides the 85W pass-through charging?

The rear USB-C port labelled PD IN accepts up to 100W input and delivers up to 85W to the host laptop.

What does dual 4K@60Hz actually require from my laptop?

Windows needs a USB-C port with DP 1.4 and DSC; macOS needs DP 1.4 and will mirror both external monitors.

What speed does the Gigabit Ethernet port cap at in practice?

The RJ45 port is rated at 1Gbps, so wired network throughput tops out at that speed.
