USB-C dual 4K 60Hz HDMI adapter

This Advantech USB-C adapter drives two independent 4K 60Hz HDMI displays from a single USB-C, Thunderbolt or USB4 port with DisplayPort Alternate Mode. It targets Windows 10, 11+ and ChromeOS 100 or later users who need extended desktop space without a full docking station. The plug-and-play MST design requires no driver installation and supports HDCP for streaming services.

Sustained dual-display operation

The adapter maintains two 4K 60Hz streams continuously using the host GPU and an onboard MST chip rather than compressing video over USB bandwidth. If the host only provides DP 1.2, both outputs run at 1080p 60Hz instead. The ABS enclosure and short cable keep the unit cool during extended sessions without active cooling.

DP Alternate Mode requirement

This product only works on laptops whose USB-C port implements DisplayPort 1.2 or 1.4 Alternate Mode; macOS is not supported. Buyers whose systems lack DP Alt Mode or who need more than two displays cannot use this adapter.

Questions about this item

Does the adapter generate noticeable heat or fan noise when driving two 4K 60Hz monitors all day?

The adapter has no fan and runs silently; its ABS housing stays cool during typical office workloads with dual 4K 60Hz output.

What must my laptop already have for this adapter to work?

A full-featured USB-C port with DP Alternate Mode 1.4 support, running Windows 10 or 11 or ChromeOS 100 or later.

If I connect one 4K monitor and one older 1080p display, will both run at their native resolutions?

Yes — the MST chip drives each HDMI port independently, so the 4K screen runs at 4K 60Hz and the 1080p screen at 1080p 60Hz simultaneously.
