I bought this C3 TV a couple of weeks ago and it is working well so far. It has so many features that it will take us awhile to get used to them. The black level and contrast are amazing. No problem with the brightness even though it is in a fairly bright room. It's too soon to tell if there is an image retention problem. I didn't rate the sound because I use the TV with an AV amplifier. The digital sound output is good though.
[This review was collected as part of a promotion.] I bought this set 2 months ago and I have been very happy with the picture quality and ease of installation. I also bought an LG sound bar to go with the tv and the installation was easy and seamless. The ease of use is great !
I purchased my LG55C3 two weeks age and am very pleased with the color and brightness of the picture it produces. Things were a bit rough doing the set up owing to the poor quality of instructions that are provided. The single page seems like a one size fits all approach with simplistic graphics that were difficult to translate to the real world.
[This review was collected as part of a promotion.] I am so happy that I purchased the 65” LG C3 TV! The picture quality is wonderful. The vibrant colors are unlike any previous TV I have owned. 4K movies look amazing. I love this TV.
