How to connect a Samsung phone to TV with HDMI and DeX

- On a phone using Smart View or a similar button, open the same menu and look for your TV as the connected device.
Android screen mirroring vs casting
Mirroring copies everything on the phone, while casting sends one piece of content. An iPhone uses AirPlay to mirror to a TV instead, so a household with both phone types can compare casting on any phone.
| Screen mirroring | Casting | |
|---|---|---|
| Works with | Any app on the phone | Only apps that support casting |
| What the TV shows | The whole phone screen | Only the content you selected |
| Control | From the phone | From the phone or the Roku remote |
| Phone during playback | Must stay powered on | Free for other tasks, and it can even be turned off |
How to stop screen mirroring on Android
- From the Google Home app, tap and hold the TV's tile, then tap Stop mirroring.
- From a Roku device, press Home on the Roku remote.
- From the phone, open the mirroring menu and deselect or disconnect the TV.
- From the output switcher, select This phone to bring a cast video back.

Does Android have screen mirroring?
Yes. The feature goes by names such as Smart View, Screen casting, Wireless display or Cast. Android 8.0 or later can also mirror to Google streaming devices through the Google Home app.

Does screen mirroring use a lot of Wi-Fi data?
Neither Google nor Roku publishes a figure for mirroring. The session runs over your Wi-Fi network between the phone and TV, and any video you play from an app on the phone still streams to the phone.
Can I still use my phone while screen mirroring?
Yes, and you control everything from the phone. Everything you open also appears on the TV, including buttons and menus. Casting from a supported app leaves the phone free for other tasks without showing them on the TV.
Can I screen mirror without Wi-Fi?
Google and Roku both require the phone and TV device to share a network, and Google has retired Chromecast guest mode. A compatible Samsung phone can connect by USB-C to HDMI cable through DeX instead of Wi-Fi.

Roku says the phone must stay powered on for the whole session when mirroring, and neither Roku nor Google documents mirroring from a locked phone. To keep a video playing with the phone off, cast it from a supported app.
