What People Are Saying

Rated 1 out of 5 by from Worst tv and customer support TV does not have remote or functions to follow that are availbable on line, in the box or with customer service. Cannot sign in, can't search for apps. Live chat was sending me google links to other tvs tutorials.

Rated 5 out of 5 by from I like that the picture is sharp I have had my new TV for about 2 weeks, and I wish I had replaced the plasma TV a long time ago

Rated 5 out of 5 by from Fantastic TV I've bought LG TVs since about 2007, and they just keep getting better. The menu options are straight forward and seem more accessible than most TVs. Picture quality is great... I only wish I'd gone larger, as the basement area is pretty large and makes the TV look smaller than it is. Even so, I have no problem seeing the tiny text and indicators that game-makers insist on putting in every game, these days. I'd buy it again, if I could go back and decide again.

Rated 4 out of 5 by from Good Value for an HDTV All around good value. I wish it had at least 4 HDMI ports, it only has 3. I'll buy LG again, looking at a 4K HDR TV by LG now.
