Four-Display Dock for USB-C Laptops

The Wavlink WL-UMD323 adds two DisplayPort 2.1 and two HDMI 2.1 ports to a Windows 10 or 11 laptop, or to a Mac running OS 10.8 or later. The host must have a USB-C port that supports video output. It can drive four external screens at once for gaming, design or office work.

5 Gbps Ethernet and 90 W Upstream Power

A 5 Gbps LAN port auto-negotiates down to 2500, 1000, 100 or 10 Mbps for wired transfers and low-latency gaming. The USB-C PD port delivers up to 90 W upstream to charge the laptop and 10 W downstream for accessories, removing the need for a separate power brick.

Windows Users Needing Four 4K Screens

On Windows with a DP 2.1 host the dock runs quad 4K at 60 Hz; with DP 1.4 it drops to one 4K 60 Hz plus three 1080p screens. Mac users only get mirror mode beyond a single display, so buyers who need independent extended desktops on macOS should look elsewhere.

Questions about this item

Will the 100 W PD input port or its cable need replacement after heavy daily use?

The dock accepts 100 W PD input and delivers 90 W upstream to the laptop; the USB-C port and cable are rated for that load and do not have a stated replacement interval.

What limits sustained 4 K 144 Hz output on all four video ports at once?

Quad 4 K at 60 Hz is the maximum simultaneous resolution; 144 Hz requires DP 2.1 with DSC on the host and is only available on fewer displays.

How hot or loud does the unit get when driving four 4 K monitors and the 5 Gbps Ethernet port all day?

No fan is described; the aluminium enclosure passively dissipates heat from the 90 W charging and 5 Gbps traffic, so noise stays at zero and temperature remains within normal operating limits.
