How can I AirPlay content without Apple TV

You don't need to use AirPlay at all if you use a Lighting Digital AV Adapter.

The adapter plugs into the lighting port on your iOS device and connects your iOS device directly to the TV via HDMI. The screen on your iOS device will automatically appear on your TV (when the TV is set to the matching HDMI input in which your iOS device is connected).

You can also charge your device while it is connected to the TV with the adapter.

I don't believe you can currently assuming your are talking about TVs.

Apple's Airplay is licensed to 3rd party manufacturers for audio output, but as far as I'm aware not for video output currently.

You may find if your TV has a protocol similar to Airplay there may be a 3rd party app that could output some content but I suspect mirroring of all screen content on iOS would be prohibited for several reasons.

What are you trying to mirror ?

If say you wanted to see a desktop display on iOS to control the desktop remotely, you could using one of many screen sharing software solutions.

I also believe there was a method to record AppleTV output in Quicktime eg to record game play, but I've never tried this, and it won't work over USB C with ATV 4k as it no longer has USB C.

Hi, glad to tell you that you have the opportunity to mirror iPhone to TV without Apple TV, the premise is that you have an iPhone with iOS 11 system. And you just need to use the third-party apps to do it. There are many kinds of such apps in AppStore. The process in not very complicated. 🙂

I don't think so, but can't say I've checked recently as it's not something I need to use.

Hopefully someone will offer a recommendation if there is such an app.

Good luck.

You would need to have a TV that supports screen mirroring, refer to your manual. It won’t be using airplay (that is specific to Apple) but typically Miracast or Chromecast protocol.

you can get adaptors both to Ios and to macs which let you display on your tv though of cause that would mean a wire comes into the setup
