Samsung 55JS9000 4K Ultra HD Smart is future pack smart TV from elite brand Samsung. Really appreciate nano crystals technology used which will make more and dense clarity in picture. Finally, the Octa-Cor processor and ClearMotion 240 refresh rate work together to create a smoothness of motion that is more than good enough for even the most fast paced action scenes in ultra HD movies, games and TV shows. While some people have complained about ClearMotion technology’s tendency to create a sort of bizarre visual experience in movies, it is a very useful technology when it comes to sportscasts.
