Rated 5 out of 5 by from Love my TV! I've had this tv for over a month now and I love it! When I first got it though, I was disappointed until I did research and found 4k sites and better streaming sites. The cable box was just not cutting it! Just do your research and explore and you'll be in heaven. Next TV will be an LG.

Rated 5 out of 5 by from Easy to use Smart TV Had this TV about a month now. There is virtually no blurring during fast action. The colors are very clear and the sound is very good after I set it for wall display mod. The TV has many individual controls to customized picture and sound to your individual tastes.

Rated 5 out of 5 by from I bought this TV on October 1, 2016 and I couldn't be happier with your product, the picture couldn't possibly be any better. Watching sporting is like your one of the fans with great seats. I previosily had a 47 inch LG television and even that picture is as good as the day I bought it 6 years ago. Once I buy a quality product, I will stay very loyal to that Company that builds Quality Products, at a reasonable price and stands behind their products and that's why I will always buy LG products when I need any kind of electronics, and I wouldn't hesitate to buy any of your other products as well. Please pass on my thanks to your employees who build your great products, but Quality products are built I would imagine that from Top to Bottom the one word they believe in is QUALITY, and in closing ; THANKS TO ALL THE EMPLOYEES WORKING AT LG FOR YOUR GREAT PRODUCTS!!!!!!

Rated 5 out of 5 by from Great 4K TV for its price Bought this unit from Walmart during the Xmas sale. Took it home - with the box it fit into the trunk of my car nicely - myself without any other assistance. Installation is simple. It has built-in wi-fi which talks to my wireless router directly. Wireless setup is fairly simple. The picture quality is very good. Connection to Netflix is easy. It is an excellent replacement for my smaller HD screen.
