To be compatible with the Apple TV, your TV has to be an HDTV capable of 1080p or 720p resolution (supposedly the 4th generation Apple TV will be capable of 4K resolution, so you would need a 4K Ultra HDTV in order to view that resolution, but it will also work on 1080p and 720p).Which is better Roku or Apple TV?
The Apple TV 4K is the better all-around media player with faster speeds, more storage, and Dolby Vision support, but the Roku Ultra is the best option if you want to spend less. It offers many of the same features for $100 less. It can stream 4K HDR content, has an optical audio output, and a USB port.Can I use an Apple TV without a TV?
Most applications on Apple TV offer the ability to subscribe to their content without a TV Provider. You were only able to access those shows because you were a cable subscriber.
