A:AnswerI can not talk to why the different refresh rates, But you will not be disappointed in picture clarity and smoothness in action scenes, I love this television.
A:AnswerHello, John!
No, the TV speaker will be automatically disabled once you go on wireless connection. The only way to make that work is to hook up the Headphones using a cable to the Headphone port. Please refer to the link below:
