Do I have to have a special item to watch Apple Tv
what do I need to get so that I can watch Apple TV on my regular television ?
Question marked as
If you have a “smart” TV with the Apple TV app available, load that.
If your TV has an HDMI input and you have an iPhone or iPad with an HDMI adapter, you can use that and a cable.
An Apple TV 4K box can be purchased and connected, too.
There are other ways.
