USB-C dual-HDMI adapter for multi-monitor setups

This USB-C hub adds two HDMI outputs, one USB 3.0 port and 100 W power delivery to laptops that support Thunderbolt 3 or DisplayPort 1.4 alt mode. It works with Windows, macOS, Linux and Android devices that meet the video-output requirement. The adapter is bus-powered and requires no driver installation. It is not suitable for USB-C ports that lack video alt mode.

Thermals noise and power draw

The unit draws power from the host USB-C port and passes up to 100 W through its PD port for laptop charging. No external power supply is needed and no active cooling is present, so operation is silent. Power consumption scales with the number of connected displays and the USB 3.0 load. Heat remains low during typical office use with two 4K monitors.

Replaces single-port dongles when you need two

It upgrades from a basic USB-C to HDMI dongle by providing dual 4K@30 Hz outputs plus a USB 3.0 data port and charging passthrough. The jump is worth it when your laptop has only one video-capable USB-C port and you need extended desktop mode on Windows or mirrored/extended modes on macOS. It does not support MST on macOS, so three unique streams are not possible on that platform.

Questions about this item

How do I install the MCHOSE USB C Dual HDMI Adapter and which port requirement is often missed?

Connect the adapter to a USB-C port that supports Thunderbolt 3 or DP 1.4 alt mode; the step people miss is confirming their laptop's port actually carries video-out before plugging in.

What maintenance or replacement will the MCHOSE USB C Dual HDMI Adapter need over time?

No routine maintenance is required; if the HDMI cables or the adapter itself fail, replace the faulty cable or the whole hub as a unit.

What is the first limit that appears when driving two 4K displays continuously with the MCHOSE USB C Dual HDMI Adapter?

The dual-HDMI output caps at 30 Hz per screen, so sustained 4K work hits that refresh ceiling before bandwidth or thermal limits.
