Hi Teepee27,

You can use AirPlay to stream or share content from your Apple devices to your Apple TV, AirPlay-compatible smart TV, or Mac. 

Please check out this link, which has more information about the requirements and process, and may be helpful: Use AirPlay to stream video or mirror the screen of your iPhone or iPad

Stream video from your iPhone or iPad to a TV or Mac

1. Connect your device to the same Wi-Fi network as your Apple TV, AirPlay-compatible smart TV, or Mac.

2. Find the video that you want to stream.

3. Tap AirPlay . In some apps, you might need to tap a different button first.1 For example, in the Photos app, tap Share , then tap AirPlay .

4. Choose your TV or Mac from the list.

To stop streaming, tap AirPlay  in the app that you're streaming from, then tap your iPhone or iPad from the list.
