What People Are Saying

Rated 2 out of 5 by from Expensive for very limited features, poor support. Overall, the TV is a good one. However, after buying it, I realized how limited it is. For examples, it only has two HDMI ports, of which only one is ARC. This severely limits how you can configure your home entertainment system. The picture quality is good, but this television does not support HDR (High Dynamic Range) color and was technologically obsolete months after I bought it. Not only that, but I have to use my amplifier as a switch because of the lack of HDMI ports with which to connect Apple TV, my Blu-Ray Player, my amplifier etc. I will never buy another smart TV with less than four ports, of which all should be HDR and ARC capable.

Rated 1 out of 5 by from Loss of Internet While the picture is fine and the price was good, the tv itself has lost the ability to connect to the Internet. All my other devices to include another smart tv (not an LG) connect and stay connected with no problem. We've trued numerous times and yes, i am inputting in the password correctly. Really not good. I've read that this is a problem with LGs. Terible. [This review was collected as part of a promotion.]

Rated 5 out of 5 by from LG #1 of 4 Love my LG TV's. I just wish this one had a magic remote like my others do. It's a pain to use the up and down buttons to key in data for the smart tv apps. Other than that --- it's awesome. [This review was collected as part of a promotion.]
