Mirroring or casting a screen to a compatible TV with a Galaxy S21 is quick and easy to do.
The Samsung Galaxy S21 has a built-in feature for mirroring your phone with your TV using Miracast.
Miracast works wirelessly directly to transmit to the TV and does not use WiFi.
The option to do this is called Smart View and is available from the menu.
The TV being used will need to have Miracast built-in which often will automatically come up on the phone when Smart View is selected.
Each TV will be sightly different depending on the manufacture.
If your TV does not have Miracast technology, the Galaxy S21 can also screen mirror with an USB-C to HDMI cable.
While using a cable is not as free as wireless, it works just as well.
