What people are saying

Rated 2 out of 5 by from Disappointment, poor warranty I have had this tv since November. I was very excited when I decided to buy this television as I have a b955 inch that has served me very well and is an excellent television. This c377 is a major disappointment. It has visible banding and inconsistencies that run horizontally across the screen. I let LG know about the issue and when they sent technicians over to fix my tv they choose to not authorize a panel replacement because the defect can only be seen in darker scenes. Dark scenes is what OLED is supposed to be particularly good at so this is a major disappointment. Paying for a premium television you would expect a premium product and unfortunately I have ended up with a 2500 dollar disappointment.

Rated 1 out of 5 by from Did not work with PCs I understand that this is a TV first and foremost, but this product is marketed as having PC and gaming support/features. Nothing but issues trying to get reliable PC picture. Constant black/rainbow flickering in games. I tried three different hdmi cables, All certified 8k. There are many complaints regarding this issue online. Users have had to change cables, wiggle cables, hang cables in a certain way, and that's not a solution. I don't know if it's bad connectors on the TV or if it's GPU incompatibility. Another PC would not always be recognized by the TV. None of these issues happen on my current monitors using the same cables.

Rated 1 out of 5 by from Horrible Customer Service- Won’t Turn On This TV is amazing- we loved it! However— after just shy of THREE months, out of no where, it won’t turn on!! We have tried EVERYTHING. We have not taken it apart because we don’t want to void the warranty but we’ve tried restarting it and different outlets- you name it. We are VERY frustrated because it is an expensive TV and we haven’t had it that long. THREE MONTHS!? And it won’t turn on. LG— your support team is NO HELP. We have been waiting for THREE WEEKS to get a repair or new TV and no one from LG is taking responsibility for it!! No one is helping they just keep saying “don’t worry your claim is being reviewed.” They said it’d be about a week and it’s going on the third week!! We are SO FRUSTRATED!!😣 !!!!
