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 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.
There is also a video at the bottom of this post to further assist you with a video walk-through if needed.

Screen mirroring to a TV with Miracast is quick and easy to do.
The TV will need to have Miracast built-in which most new TVs will have.
If the TV does not have Miracast you can also use a cable which is easy to do.
The wireless connection allows you a little more freedom as your phone is not tethered to a cord.
There are also several different mirroring apps available, you can use any of those apps and they should work similarly to Smart View.
If you notice a lag, you can connect using the cable to correct this issue. The steps will also work to mirror your computer screen and projector.
