How do you screen mirror using Apple TV?

To screen mirror content onto an Apple TV, one first ensures that the device they wish to mirror from and the Apple TV are both connected to the same Wi-Fi network. On an iPhone, iPad, or a Mac, one swipes down from the upper-right corner or clicks on the Menu bar icon to access the Control Center and selects the “Screen Mirroring” option. Then, they simply choose their Apple TV from the list of available devices. If AirPlay is not already enabled on the Apple TV, you might need to go to Settings on your Apple TV to turn it on. For some applications, another method can be used by tapping or clicking the AirPlay icon within the app itself and selecting the Apple TV. After a successful connection, the screen contents of your device will appear on your TV. If prompted for a code, it is entered as it appears on the TV screen to establish a secure connection.
