Dual 4K 60Hz output

This USB-C adapter drives two external monitors at up to 3840x2160 at 60Hz from a single port. It works with laptops, tablets and phones that support video over USB-C or Thunderbolt 3. Windows systems can extend or mirror the desktop across both screens. macOS is limited to mirror mode only, so the two displays always show the same image.

100W pass-through charging and 3.5mm audio

A dedicated USB-C power delivery port accepts up to 100W from the device's original charger, keeping the host powered while the adapter is in use. The built-in 3.5mm jack adds analogue audio output for headphones or speakers without needing a separate dongle. No external power supply is required for the adapter itself.

Resolution range and OS constraints

Supported resolutions span from 640x480 at 60Hz up to 3840x2160 at 60Hz, covering common office and media formats. The adapter relies on the host's GPU for video processing, so performance scales with the connected device. It will not function on USB-C ports that lack video alt-mode support, such as certain HP Pavilion models.

Questions about this item

Will the 3.5 mm audio jack or the 100 W USB-C charging port need replacement after heavy daily use?

Both ports are solid-state connectors with no moving parts, so they do not wear out in normal use; keep them free of dust and avoid bending cables sharply at the plug.

What is the first limit reached when driving two 4K 60 Hz displays continuously?

The adapter tops out at 3840×2160 at 60 Hz per screen, so bandwidth is the limiting factor; it cannot push higher resolutions or refresh rates.

How much heat or fan noise does the hub produce when running all day with dual monitors and 100 W pass-through charging?

The unit has no fan and relies on its aluminium casing for passive cooling; it becomes warm but stays within safe operating temperatures during sustained loads.
