Short answer

Galaxy S8 and newer S phones, Note8 and newer, and most Galaxy Tab S tablets work with a USB-C to HDMI adapter and an HDMI cable. Most Galaxy A phones and the Z Flip cannot send video by cable, so mirror wirelessly instead.

These go with the USB-C to HDMI adapter with charging.

How to connect it

  1. Check your model is on Samsung's DeX list (Galaxy S8 or newer S series, Note8 or newer, most Tab S tablets).
  2. Plug the adapter into the phone's USB-C port and run an HDMI cable to the TV.
  3. Switch the TV to that HDMI input. The phone mirrors, or offers Samsung DeX.
  4. No luck? Use Smart View to a Samsung TV, or a casting device such as a Google TV Streamer.

Check this first

  • Galaxy S8 and newer S phones, Note8 and newer, and most Galaxy Tab S tablets send video through USB-C. Most Galaxy A phones and the Z Flip do not, so mirror wirelessly instead (Smart View to a Samsung TV, or a casting device). Samsung's DeX page lists every model.
  • Your phone or tablet must be able to send video through USB-C. Many Android phones cannot.
  • You also need an HDMI cable.
  • For 4K at 60 Hz, pick an adapter that lists 4K 60 Hz (HDMI 2.0).
  • It mirrors your screen. Some streaming apps block video through a cable; if yours does, open that service's own app on the TV instead.

Questions people ask

Does my Galaxy A phone work with an HDMI adapter?

Usually not. Most Galaxy A phones cannot send video through USB-C. Mirror wirelessly instead.

Why do some streaming apps show a black screen?

Some streaming apps block video through cables and adapters to protect their content. If that happens, tap the cast or AirPlay button inside the app to send the video to a smart TV or streaming box, or open that service's own app on the TV.
