Screen sharing to Apple TV works through AirPlay, Apple's wireless casting system

To share your screen to Apple TV, you use AirPlay, which is built into every Apple device. AirPlay sends what you see on your iPhone, iPad, or Mac directly to your TV without cables. The process takes about 10 seconds once everything is set up correctly.

The core requirement is straightforward: your Apple device and your Apple TV must be on the same Wi-Fi network. They don't need to be the same model or generation—AirPlay works across most Apple devices made in the last several years. Once they're on the same network, your device will see your Apple TV as a casting option.

What you're actually doing is telling your device to send its display output wirelessly to the TV. The TV receives that signal and shows it on the screen. You control everything from your device—the TV is just the display.

Key Takeaways

  • Your Apple device and Apple TV must be connected to the same Wi-Fi network before screen sharing will work.
  • On iPhone and iPad, swipe up from the bottom to open Control Center, tap Screen Mirroring, and select your Apple TV from the list.
  • On Mac, click the Control Center icon in the top-right corner, select Screen Mirroring, and choose your Apple TV.
  • If your Apple TV doesn't appear in the list, restart both devices and check that they're on the same network.
  • Screen sharing drains battery on phones and tablets, so plug in your device if you plan to mirror for more than a few minutes.

Screen sharing from iPhone or iPad

Open Control Center by swiping up from the bottom of the screen (or swiping down from the top-right on newer models). Look for the Screen Mirroring button—it looks like a rectangle with a triangle at the bottom. Tap it.

A list of available devices appears. Your Apple TV will show up by name. Tap it. Your iPhone or iPad will ask you to confirm—tap Start Mirroring. Within a few seconds, your screen appears on the TV. The status bar at the top of your device turns blue to show mirroring is active.

To stop mirroring, open Control Center again, tap Screen Mirroring, and select Stop Mirroring. Your device's display returns to normal.

Screen sharing from a Mac

Click the Control Center icon in the top-right corner of your menu bar (it looks like a grid of dots). Select Screen Mirroring from the dropdown menu. A list of available devices appears—select your Apple TV by name.

Your Mac will mirror to the TV when ready. A small menu bar icon appears to show mirroring is active. To stop, click Control Center again, select Screen Mirroring, and choose Stop Mirroring.

On older Macs without Control Center, use the menu bar instead: click the AirPlay icon (it looks like a triangle in a rectangle) and select your Apple TV from the list.

What to do when your Apple TV doesn't appear

If you don't see your Apple TV in the Screen Mirroring list, the most common cause is that your device and TV are on different networks. Check your device's Wi-Fi settings and make sure it's connected to the same network name as your Apple TV. You can find the network your Apple TV is on in the TV's Settings app under Network.

Restart both devices if they're on the same network but still not connecting. Unplug your Apple TV for 10 seconds, then plug it back in. Restart your iPhone, iPad, or Mac normally. Once both devices are back on, try Screen Mirroring again.

If the problem persists, check that your Wi-Fi router is working properly by testing internet speed on another device. Some older routers struggle with multiple devices on the same network. Moving closer to the router can also help if the signal is weak.

Network and Wi-Fi requirements

Both your Apple device and Apple TV need to be on the same Wi-Fi network. This is the single most important requirement. They can be on a 2.4 GHz or 5 GHz band—AirPlay works on both, though 5 GHz is faster and more stable if your device supports it.

You don't need internet access for screen sharing to work. As long as both devices are connected to the same local Wi-Fi network, they can talk to each other. This means screen sharing will work even if your Wi-Fi network isn't connected to the internet.

If you're on a guest network or a network that isolates devices from each other, screen sharing won't work. Ask your network administrator to enable device-to-device communication, or connect both devices to a standard home or office network instead.

Battery and performance considerations

Screen mirroring uses significant battery power on phones and tablets. If you're mirroring from an iPhone or iPad, plug it into power before you start. A typical mirroring session drains 10 to 15 percent of battery per hour, so an unplugged device will run out quickly during a long presentation or video playback.

Mirroring also uses Wi-Fi bandwidth. If other devices on your network are downloading large files or streaming video, screen sharing may lag or drop. Close bandwidth-heavy apps on other devices if you notice stuttering or delays.

On Mac, battery drain is less severe, but plugging in is still recommended for extended use. Closing unnecessary apps on your Mac before mirroring can improve performance.

Troubleshooting common problems

Screen mirroring is laggy or keeps disconnecting. Move closer to your Wi-Fi router. Check that no other devices are downloading large files. Restart your Apple TV and your device. If the problem continues, your Wi-Fi signal may be too weak—consider moving the router or using a Wi-Fi extender.

Audio is coming from your device instead of the TV. This is normal for some apps. Open the app's settings and look for an audio or speaker option. Some apps require you to manually switch audio output to the TV. You can also adjust volume using your Apple TV remote while mirroring.

The picture is stretched or the wrong size on the TV. Check your Apple TV's display settings. Go to Settings > Video and Audio > Resolution and make sure it matches your TV's native resolution. You may also need to adjust your TV's picture settings to fit the screen properly.

You see a black screen or the TV says "no signal." Make sure your Apple TV is powered on and set to the correct input. Check that both devices are on the same Wi-Fi network. Restart your Apple TV by unplugging it for 10 seconds.

Frequently Asked Questions

Can I screen share to Apple TV from a Windows computer?

No. AirPlay is exclusive to Apple devices. Windows computers cannot screen share to Apple TV natively. You would need to use a third-party app or connect your Windows device to the TV using an HDMI cable instead.

Does screen sharing work over cellular or mobile hotspot?

No. Both devices must be on the same local Wi-Fi network. Cellular data and mobile hotspots don't create the local connection that AirPlay requires. You need a standard Wi-Fi router that both devices can connect to.

Can I use my device while screen sharing?

Yes. Everything you do on your device appears on the TV in real time. You can open apps, type, swipe, and use your device normally. The TV straightforward displays whatever is on your screen.

What Apple TV models support screen sharing?

AirPlay works on Apple TV 4K (all generations), Apple TV HD, and Apple TV (3rd generation and later). Older models may have limited support. Check your Apple TV's Settings app under AirPlay to confirm it's enabled.

Is screen sharing find?

AirPlay uses encryption to protect the connection between your device and Apple TV. Only devices on your local Wi-Fi network can see your Apple TV, and you control when mirroring starts and stops. Your data doesn't go through the internet—it stays on your local network.
