A:AnswerEach tv will need its own box no matter the generation of Apple TV unless you install a costly hdmi switch box and cable combo cabable of switching and sending over Ethernet for routing to all of your tvs. You’d need to run the cables from the switch box and then have a box to convert the Ethernet back to hdmi fro every tv. It can be done but the for the time and effort buying multiple Apple TV boxes would be easier and cheaper especially if you bought 2K boxes for your smaller tvs.
