3-in-1 USB-C Adapter with 4K HDMI

The AJMRTC adapter adds 4K HDMI output, a 5 Gbps USB 3.0 port and USB-C Power Delivery charging through a single Type-C connection. It supports 3840×2160 resolution at 30 Hz for mirroring or extending a display. The gold aluminium shell provides passive cooling in a compact form factor. No driver installation is required for immediate use.

Suits ultrabook and tablet users needing video.

Professionals who connect a laptop or tablet to a projector, monitor or TV while charging and attaching a flash drive or keyboard will benefit. Users whose USB-C port lacks DisplayPort Alt Mode or Thunderbolt 3 support cannot use the video function. Buyers requiring 4K output at 60 Hz or multiple video outputs should look at a different solution.

4K@30Hz HDMI output decides compatibility

The single specification that determines fit is the HDMI port’s maximum resolution of 3840×2160 at 30 Hz. If the connected display or usage scenario demands a higher refresh rate or a different video interface, this adapter will not meet the requirement.

Questions about this item

How do I connect the AJMRTC adapter to my laptop and external display?

Plug the USB-C connector into a Thunderbolt 3 or DP Alt Mode port, then attach an HDMI cable from the adapter to your monitor or projector.

Will the HDMI port or USB 3.0 port wear out and need replacement?

The ports are solid-state with no moving parts; under normal use they do not require scheduled replacement.

What resolution limit appears first when I drive a 4K display for long periods?

The HDMI output is capped at 3840×2160 at 30 Hz, so sustained 4K work stays at that refresh rate.
