Dual 4K output adapter

This LUOM USB-C hub connects a single Type-C port to two HDMI displays, a 3.5 mm audio jack and a 100 W pass-through charging port. It supports resolutions from 640x480 up to 3840x2160 at 60 Hz and includes a 2 ft 4K HDMI cable. The Thunderbolt-compatible adapter works plug-and-play without driver installation.

Windows extend mode versus Mac mirror only

Windows laptops with Intel CPUs and video-capable Type-C ports can run two independent extended screens or mirror mode. MacOS and mobile devices with video-capable USB-C are limited to a single extended desktop mirrored across both external monitors. Systems using Celeron processors or ports without video output cannot use the adapter for external displays.

Bundled cable and power delivery

The included 2 ft HDMI cable lets one monitor connect immediately without a separate purchase. The 100 W Type-C charging port keeps the host laptop powered while both displays and audio are active, reducing cable clutter on the desk. No external power brick is required for the hub itself.

Questions about this item

Does my laptop need a USB-C port that carries video to use both HDMI outputs?

Yes, the host USB-C port must support video output; on Windows the CPU must be an Intel Core processor, not a Celeron, and on macOS both external monitors will show the same extended image.

Will the adapter pass 100 W charging through to my laptop while driving two 4K displays?

The built-in USB-C charging port accepts up to 100 W power delivery so the laptop stays powered while both HDMI ports run at 3840x2160@60Hz.

How can I verify both monitors are running at 4K 60 Hz after I plug everything in?

Open the display settings on Windows or System Settings on macOS and confirm each external screen is set to 3840x2160 at 60 Hz.
