What People Are Saying

Rated 4 out of 5 by from Great Picture The ease of setup was great. The picture is awesome for such a small TV. I gave four stars only because once you put the TV on the stand it titles forward and it cannot be adjusted.

Rated 5 out of 5 by from Excellent TV We bought this TV about a month ago for the sewing room. The receiver brings in more air wave antenna stations than the previous TV we had there and the signals are stronger. Also, the picture is better, brighter colors and clearer picture than our previous TV there.

Rated 1 out of 5 by from Not useable I bought this to use in an area that I have no cable access. Wanted it to get the regular channels CBS, ABC, and NBC. I have Comcast for my Internet and I have found no way to use this TV.

Rated 5 out of 5 by from Clear picture, true colors I bought this as just an extra smart t.v. for my small apartment, and since I've already had an L.G. for the living room for a couple years that gets almost constant use and has never had an issue, I went with the same brand. It didn't hurt that it was also a great price! I love that it fits on my bedroom stand, and the white edge looks nice with my other decor. It's small enough to move around or take to a friends house, and also has true colors and a clear picture for gaming.

Rated 5 out of 5 by from Love the look I'm so happy I chose this TV. I like that it is white for the kitchen. My appliances are white so it looks very nice on the counter. The smart TV freature is a plus for watching Net Flix and Amazon Prime.

When will Youtube tv be available for this model in the lg apps?

Asked by: seibertspace
I talked to Youtube about this and they will never have the app on this TV. The reason is it is not compatible with this operating system or store. I've asked Youtube to update their supported devices page.
