It depends on your budget and purpose. If you just need a new TV for the living room, for example, pay attention to Samsung QN90A. It’s affordable but a quality option, personally, I like it. Also, think about TV installation in advance as it’s better to hire specialists to do that.
If you are going to buy TV, I suggest to take a look at Samsung. As for me, it is a really good firm but don’t forget about drivers. I was using TV-tuner drivers download where are all the necessary drivers that you can download without any problems, just with one click.
