[This review was collected as part of a promotion.] Brilliant TV, easy to use and set up, stunning picture and works great with my Denon AVR.

Overloaded.
The picture and sound are excellent. That's as far as it goes. The TV is loaded with apps and loads of programs which I don't want. Setting up is relatively easy. No Teletext is a mistake by LG. If you want loads of apps ect it's a good buy. If not, look elsewhere, and save money.

The Tv is a must have for every home this season.
Ì bought LG 55 Inch OLED55C55LA Smart 4K UHD HDR OLED TV about 5 months ago.

What a fabulous TV!
Read some negative reviews about the sound quality with this one but as i have a home cinema kit i wasn't too bothered, BUT, i spent some time with the settings, which is very easy anyway, just tweaking things as i went along and not only does this TV deliver on picture quality but the on-board sound is terrific, i was surprised with the bass as the TV is so thin. For less than £1000 as i got a discount code as well, this TV punches well above it's price tag. In fact i cannot find a single negative thing to say about it.

Excellent picture
Excellent tv. I was going to go with the G5 but I’m glad I saved money by going for this. Sound not very loud on the tv but this is in a Dolby Atmos media wall so is excellent

Love this TV
[This review was collected as part of a promotion.] Love this TV, the colour is amazing, but above all, the sound is absolutely incredible. It sounds as if we have a soundbar attached to it when we don’t. It’s also AI powered so when it’s dark or light in the room, it will adjust the brightness of the screen for us
