What it is

This USB-C to HDMI adapter connects a laptop or phone with a USB-C 3.1 or Thunderbolt 3 port that supports DisplayPort Alternate Mode to an HDMI display, TV or projector. It delivers video and audio up to 3840x2160 at 30 Hz and is backward compatible with 1080p, 720p, 480p and 360p resolutions. No drivers or wireless connection are required.

Who it suits and who it does not

It suits users with compatible USB-C 3.1 or Thunderbolt 3 devices who want to mirror or extend their screen for presentations or media playback on a larger display. It does not suit owners of USB-C ports that lack DisplayPort Alternate Mode, buyers who need 4K output at 60 Hz, or anyone whose host device only offers USB 2.0 or basic charging over USB-C.

The deciding specification

The adapter only functions with USB-C 3.1 or Thunderbolt 3 ports that explicitly support DisplayPort Alternate Mode; ports without that capability will not transmit video.
