The good: I haven’t even viewed any 4 K content yet, but with broadcast TV and streaming videos from you tube via chrome cast, I can’t believe the picture quality, both resolution and colors. I watched music videos in my playlist, some of which I’ve seen hundreds of times before and I saw details and colors I had never realized were there before. I connected the relatively inexpensive LG sound bar and it sounds great, much better than the internal speakers. This is without question THE BEST TV I’ve ever owned. I just don’t see how any TV could have a better picture. I’m very pleased with this purchase. The not so good: I’m not in love with the remote or the menu system but I’m sure in time I’ll adjust to them.
