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). Your HDTV will also have to have an HDMI port, as you connect the Apple TV to your TV with an HDMI cable. The brand of TV doesn’t matter; you can use Samsung, Sony, LG, Sharp, Vizio or whatever other brand you have, as long as it meets the above requirements.
