Can you use FaceTime on an Apple TV?

No, you cannot use FaceTime directly on an Apple TV. FaceTime is a service designed for iOS and macOS devices such as iPhones, iPads, and Mac computers. However, you can use AirPlay to mirror or extend your iPhone, iPad, or Mac display onto your Apple TV, which enables you to show a FaceTime call on the bigger screen of your TV. This workaround allows everyone in the room to be part of the conversation, despite the Apple TV itself not supporting FaceTime calls as a standalone feature.
