Started great but now things took a turn…
[This review was collected as part of a promotion.] Having had this for a few months now, it started great, but now all apps keep crashing (Netflix/apple to/ prime/ bbc etc) I spoke to lg and they did all tests and changes, nothing helped. The advisor them spoke to their engineers and we tried more fixes…nothing worked. They then said speak to the app developer, but it’s not a glitch on the end of all apps for sure. Ive seen a lot of c5 oled people with the same issue and it seems like a memory or board issue. I tried to speak to LG again but I’ve got no where and Im concerned i have a very expensive paperweight instead of a beautiful Oled TV. If so many people are writing of this issue on google, YouTube and Reddit, then why do we still have the issue, or not automatic replacements or maybe upgrades? I would really love for someone from LG to see this, know that even their engineers couldn’t fix this issue and step up to assist with a real fix, replacement or upgrade to a less glitchy model.

Superb telly
[This review was collected as part of a promotion.] Fantastic ! After reviewing so many televisions I opted to stick with my go to brand, so glad I did, superb screen and os , it's familiar but new . Such a user friendly experience from opening the box to turning it on ,my only criticism is that lg should state exact heights on each size tv for the wall mounting brackets ,makes it easier to put the mount on the wall,especially on a media wall . Very happy with my purchase ,now just need to play with settings and get the soundbar sorted

Excellent picture quality and premium OLED experie
[This review was collected as part of a promotion.] Very happy with the LG OLED65C55LA. The picture quality is excellent, with deep blacks, vibrant colours and smooth motion, especially for films and streaming. The design looks premium and the smart TV interface is easy to use. Sound is decent for a slim TV, though a soundbar would make it even better. Overall, a great OLED TV and very good value.
