How to Apple AirPlay to TV and Other Screens

AirPlay allows you to stream video, audio, and photos from your Apple devices to an Apple TV, AirPlay 2-compatible smart TV, or Mac.

How to Mirror Your iPhone Screen via AirPlay

• Connect your iPhone and your Smart TV (or Apple TV) to the same Wi-Fi network.
• Open the Control Center on your iPhone:
• iPhone X or later: Swipe down from the top-right corner.
• iPhone SE or earlier: Swipe up from the bottom edge.
• Tap the Screen Mirroring icon (two overlapping rectangles).

How to Stream Specific Video or Audio Content

If you only want to stream a video without mirroring your entire screen:

• Play the video or music track inside an app (like TV, Photos, or supported third-party players).
• Tap the AirPlay icon (a rectangle with a triangle at the bottom, or an audio wave icon).
• Select your target display or speaker from the list to begin streaming instantly.

Tips for Optimal Apple Ecosystem Performance

• Keep OS Updated: Ensure iOS and watchOS are updated to the latest versions to receive critical security patches and performance improvements for Apple Pay and AirPlay.
• Verify Wi-Fi Alignment: AirPlay connection issues are almost always caused by devices being on separate Wi-Fi frequency bands (e.g., 2.4 GHz vs 5 GHz). Always ensure both devices share the exact same network SSID.
• Manage Wallet Notifications: Customize transaction alerts in Settings > Wallet & Apple Pay to track spending in real-time.
