You would need to either have a chromecast plugged in to your TV or have an Android TV, My recommendation would be to get a chromecast since it is less expensive, it will also allow you to cast from your phone to your TV and it is platform agnostic, it will work on either Android or iOS, but if you want to have a nice TV interface on your TV i would recommend getting an Android TV which provides a nicer interface for navigating through apps on your TV and also allows you to cast from your phone and TV.
