For iPhone and iPad users mirroring to Apple TV or AirPlay-compatible displays, the process involves accessing Control Center, selecting Screen Mirroring, and choosing the target device from the available options. Users should ensure both devices connect to the same wireless network and that AirPlay service remains enabled on the receiving device. The initial setup typically requires entering a four-digit code displayed on the receiving device to establish the secure connection. Subsequent connections become automatic, with devices remembering previous pairings and establishing connections more quickly. Apple documentation recommends ensuring your iOS or iPadOS version remains current, as older software versions sometimes experience compatibility issues with newer receiving devices.

Android users have multiple mirroring options depending on device manufacturer and Android version. Google's native Cast function, available through Quick Settings or through the Share menu within compatible applications, provides straightforward mirroring to Chromecast devices and Cast-compatible televisions.
