Beautiful color; rapid screen response.
I bought a 37” LG in 2010. I have since added a fire stick for streaming programming. This TV has continued to work beautifully, while 2 different larger screen sets of other manufacturers died quickly.

Amazing Picture
Great picture and the AI features are great! I gave it a four because it didn’t have the magic remote!

Why Do I have to spend extra for a remote?
Pros: great picture.
Cons: no magic remote. I bought an LG sound bar and can not control it with TV remote supplied.

Awful tv
It wants to update every app and it hangs up on YouTube tv. Remote is very sensitive and the tv lags.

Updates make it worse
Performance gets worse with each update. "Free Channels" now take forever to load.

Magic remote not in box
The “ what’s in the box “ lists the magic remote ( which is needed to link to “Alexa”!
I got the old version.
I cannot get anyone to respond.
Call 800 number all you get is busy.
