I caught this tv on a great promotion in January. I'm using it in my media room as a computer monitor/media tv. I LOVE it! I didn't realize 4K was that awesome. It has the built in smart tv which offers Netflix in 4k as well as some other apps. Lg smart tv is limited, but its quick and relatively intuitive to use. Picture and sound are both great from this tv. The one complaint i have is the remote. Holy cow. It's bad. Like really bad. In reference to how many keys there are and they are almost all the same shape. You almost have to look at this remote to tell what key you are pressing. I won't be using it much, as i will be adding steaming box soon, but it does stink. The rest of the tv is awesome. For a 4k 50in lg set, you can't beat this tv. Note, it is a 60hz set, which is fine for most viewing. The only time it may be noticeable is when watching sports. Go ahead and pick this one up if you are looking for a great deal on a 4k set.
