You can stream content from your iPhone to Apple TV, using AirPlay. You can share your photos or mirror exactly what’s on your device’s screen. Here’s how to go about it.
iPhone to Apple TV First Steps:
Make sure your iPhone is running iOS 12.3 or later and your Apple TV 4K or Apple TV HD is running tvOS 11.4 or later. Both devices must be on the same Wi-Fi network.
Play video from your iPhone with AirPlay
Open the video you wish to AirPlay to your Apple TV and tap the AirPlay icon. In some apps, such as the Photos app, you need to go through the Sharing icon to get to the AirPlay icon. From the next screen, on your iPhone, choose your Apple TV on the menu to start streaming. You can pause, fast-forward and rewind from the controls on your iPhone; just tap the screen and they appear.
To stop streaming, tap the AirPlay icon on your iPhone to get back to the list of nearby AirPlay devices; the Apple TV is currently checked. Tap your iPhone in this list to return to viewing on the small screen. Note that not every video app on the iPhone supports AirPlay. If you want to stream from a video app that doesn’t have this feature, try Screen Mirroring instead.
Screen Mirroring from the iPhone to Apple TV
On your iPhone, open the Control Centre by swiping inward from the top-right corner of the screen for Face ID iPhone’s or swipe up from the bottom of the screen if your iPhone has a Home button. Tap the Screen Mirroring icon. In the window that pops up, select your Apple TV unit. An AirPlay code might appear on your TV. If so, enter it on your iPhone. Your iPhone’s screen is mirrored to your TV and you can turn it (the iPhone) into portrait or landscape mode and the screen on your TV also changes.
On your iPhone, to stop mirroring your screen, open Control Centre, tap Screen Mirroring, then tap Stop Mirroring.
Alternatively, tap the Menu button on your Apple TV’s remote.
