If you use an iPhone or Mac and you want to cast a video from a specific app on your iPhone or Mac to your TV, you can use AirPlay. However, if you want to cast your whole screen — with all of the windows or applications you may have open — then you’ll want to use mirroring.
You can mirror your iPhone, iPad, iPod touch, or Mac screen on an Apple TV or an AirPlay 2-compatible smart TV. (Here are the system requirements.)
