Product Overview

Bring the cinema into your living room with this amazing 55 inch LG LED TV. You’ll enjoy a breathtaking picture bursting with detail thanks to its 4K Ultra HD resolution, while upscaling gives HD and Full HD content a visual boost too. The Technicolor Advanced HDR fills your screen with incredibly lifelike shades and hues to make every movie look super-realistic. Since Nano Cell technology maintains colour accuracy even at wide angles, everywhere is the best seat in the house. And there’s plenty of entertainment to keep you busy – simply connect it to your internet to access tons of catch-up and streaming services. Plus, you can sync it up with Google Home or Amazon Alexa to control it using your voice, which is great when the remote has gone AWOL.

We want you to fully enjoy your new TV, so please be careful when unpacking it – pull it out of the box using the edges so that you don’t damage the screen. If you need to return your TV for any reason, we just ask that you don’t pack the plug in front of the screen as it could damage the TV in transit.

Features we love

Superb Dolby sound and picture quality

Immerse yourself in the atmosphere of whatever you’re watching with Dolby Atmos and Dolby Vision. Cutting-edge Dolby Atmos recreates sound in 3D, so you can hear it from all directions, while Dolby Vision increases the contrast between light and dark, to create a vivid picture that’s bursting with colour. This creates an outstanding cinematic experience, for more memorable movie nights and amazing match days.

You only need to ask

LG ThinQ AI lets you control the TV, and do a whole host of other clever things too, using just your voice. It has Google Assistant built-in, which gives you full control of the TV and other smart devices in your home. So whether you want to dim the lights for movie night, or you see an advert for shampoo and want to add it to a shopping list, you can simply ask.

The most realistic blockbusters

Enjoy a brighter, vivid screen thanks to Nanocell technology. The nanoparticles work by taking any dull colours and making them more vibrant, giving you images that are true-to life. This means that all the scenes from your favourite blockbusters and shows will look as realistic as possible.

Get the cinema feel at home

Enjoy a stunning audio and visual experience with the 2nd generation a7 intelligent processor. The AI technology analyses each frame and optimises the sharpness, brightness and clarity, giving you flawless visuals in all of your films. At the same time, it also tweaks the audio so that it’ll sound just as good in rooms of all different shapes and sizes. So wherever you decide to place this TV, you’ll still get that full cinematic feeling.

Every spot is the sweet spot

This TV boasts LG’s Nano Cell technology. It offers a much wider viewing angle without any of the colours becoming faded or washed out. So no matter where you’re sat in the room, you’ll still get a sharp and vibrant picture that’s packed with colourful detail.

Nanocell is pretty impressive

Bought this just yesterday, fantastic picture, brilliant sound. I was a bit sceptical at first but the nanocell really is something, loads of different features to go at, this tv is my new toy! Would highly recommend.

As ordered

Delivery was on time and efficient, television looks great in the house.

Excellent TV

Really pleased with my purchase. Very easy to install and to follow the short-form instructions. Once fully connected to external appliances (DVD, Cable TV, Amazon Prime) via standard HDMI connections, the TV came into life with a clear, vibrant, colourful picture and fantastic sound. There is a remarkable difference when watching programmes in HD/UHD - rating = A+++++

Great picture

Fantastic picture, lots of features - what's not to like!


I found the 4K Ultra HD average really it was slightly better than my old Samsung Smart TV. Did not swivel like my Smart Samsung TV picture you need to put it on Vivid to get a bright picture. Would not buy again.

Fabulous tv

I ordered this from AO as i had an appalling experience with Currys PC World with a fridge freezer and will never set foot in that shop again. From the start, the experience with AO was brilliant. I was kept fully informed about the delivery which arrived on the day stated. It was a couple of hours late, but that was because the van had broken down and could not be helped. The app showed me this. The tv is fantastic. I managed to set it up myself and it was very straightforward. The picture quality is amazing in HD and Ultra HD. You can adjust the picture by choosing a variety of different settings. Same for the sound. You can link the tv to your phone and watch photos and your own videos on it. I'm sure I haven't yet found out everything it can do, but so far I'm delighted with it. The help screens are fairly easy to navigate through. My only slight gripe is that the Magic Remote has no forward or rewind buttons, but as I watch through my Sky TiVo box this isn't a huge problem.
