What people are saying

Rated 4 out of 5 by from Great pichture, not so great sound I bought this TV a couple of years ago, and it has a beautiful picture. It uses the OLED technology which is probably the best available to date. But for the money one would think that they could improve on the sound. Every time I change channels the volume changes especially the internet channels. It is not a complicated circuit to automatically adjust the volume. Adjust it to a comfortable level and leave it. Instead I am constantly adjusting the level. Also you will still need your Ruko if you want to watch NBC Now on the internet.
