Lasted just under 2 years don't think there's a warranty screen menus still work but can't watch any content through any means which is weird just static noise

Worst TV. Only 1 year life. Pathetic customer support. The tv is now not repairable after warranty expired.

Only lasted a year and a half! Last night, picture simply blacked out and TV blinks red lights with it not coming on. I will never buy an LG again.

4K video looks stellar, image upscaling from a 480P DVD player looks amazing. App collection is just OK for 2017. Netflix occasionally crashes. I enjoy Trumotion although the rest of the family does not like it. Depending on the price you get this TV at, it may be well worth the buy.

Excellent quality picture and great web interface and web streaming, much better than the web functionality of our Samsung smart TV that is essentially useless and we had to abandon in favor of a Roku.

After only 14 months and rarely used, our LG 49UF6400 tv has stopped working, no pictures. We bought this TV in November 2015 and has been in the bedroom but is rarely used. We only turn on the tv a couple of times per month and watch maybe an hour or two consecutively and is already broken.

For getting 4k quality you must get a 4k material trough your TV . If you get a bad quality picture for example from your cable box you won't get a 4k on your TV that's why most people they think there is no difference between 4k and 1080 or ..
