Rated 5 out of 5 by from EXCITING VISIONS The crisp picture, large format plus internet, Bluetooth and plug-in features make watching TV more than a passive pastime. Live sports make us feel like a spectator not simply a viewer. Many nature travelogues take our breath away. Best investment we made in years.

Rated 3 out of 5 by from So So I have an LG 55" smart TV so when I decided to go bigger & use the 55" in a bedroom I Looked at LG again. It had a beautiful picture in the store, but not as good in the house. I got a 4K new box from Comcast, but they said they were not transmitting in 4K yet in my area. I hope it gets better.I liked the remote much better that came with the old TV. Also, the old TV had 3D and while I did not use the 3D very often it was a nice feature.
