A:AnswerIf you have a firestick or a 4k fire TV plug in, I'm sure it will work. That connection is not about the tv's capabilities. Fire tv and the echo are both from amazon... that's how you make the connection work.
A:AnswerI used M8 x 45mm from and a Cheetah wall mount. Thread pitch was 1.25. Seemed to work good. Need to use the included spacers with the tv, they help make up for its curved back.
