A:AnswerThis television will pass Dolby Digital+ audio to the sound bar. The Apple TV 4K outputs TrueHD Atmos so it would need to be connected to the sound bar directly.
A:AnswerIt's a 60hz Tv...... Vizio is known for lies about refresh rate.... notice the " effective refresh rate " Effect of 120 hz which is not a true 120hz tv.... Scammers, run away from this company and all who work for them.... I hope someone from Vizio reads this :) Please do not purchase anything from Vizio they need to be out of business :)
