What people are saying

Rated 5 out of 5 by from Best decision Thought the price was a little too good to be true and I waited a few months before deciding to buy. Did lots of research and read many reviews. So glad I went for it! Set up was easy, size, audio and visual quality perfect. So many features it will take a while to explore them all. Only disappointment is the chrome edge, would have preferred black, No big deal though.

I have 2 LG Smart TVs ( LG55UH6550 AND LG65UH6550 )....I want to buy headphones that fully cover the ears for both TVs.  What type(s) is compatible with these Smart TV models?  Is there one headphone type that can be used on “both” TVs?

The TVs do not have a Headphone (3.5 mm) jack that you can connect wired headphones to...^IFV

How do I do picture in picture?

Asked by: Lousandy
We appreciate your interest in this television and its features. The television would not have a picture in picture function, however, it has MULTIVIEW that allows you to view content from two different sources at once. The multi-view can be launched by selecting the multi-view app from the home menu.
