I baught this LED tv in june 2017. And their is no additional features in this LED tv. This is only a TV box. No hometheatre output. No smart features. I suggest you to please dont buy this LED box. No doubt samsung is having a good picture and sound quality. But I dont find any other features. In this budget other companies provide smart features also with wifi and screen mirroring. Samsung Now this is the time to grown up. I met with a issue of speaker in this LED but it resolved by company they are taking a week to repair it is too late.
