A:AnswerI don't think you need one unless you are going to connect a sound bar and we don't need a sound bar with ours. But know this: this TV does not support Discovery plus. most of the other apps, it does, but not that one. We had to buy a Roku separately.
A:AnswerNo but if you have a phone that can airplay or what ever android has you can stream it onto the tv that way. My wife and I are using our phone to watch ESPN+ right now on this tv.
A:AnswerThis TV has a webOS platform.
