Often with football, I have the TV inside and outside playing the same game same channel but inevitably one gets ahead of the other. Because of this I mute one TV because the audio is so desynchronized it creates an awful echo sound effect. Or today, we watch the thanksgiving’s day parade on most TV’s in the house, again same problem.
It would be amazing if when you tune to the same channel that another TV is already playing in the house if it would ask if you wanted to “synchronize them” it kept them synchronized.
