To be very honest after using this brand I would recommend everyone to use it.
coming to picture quality:- up to the mark
sound:- you will love it
value for money:- reasonable and worth it buy
Usually, the difference in picture quality is minimal. The picture quality of Samsung LED TVs have hit a plateau in the last few years(except in terms of backlight uniformity). This is why Samsung has put more emphasis on their extra software features and design.
all I can say never experienced before like this.
