LG’s OLED evo tech combines supreme contrast, 100% colour accuracy, and pixel-perfect detail, all powered by the a9 Gen6 processor – together with an advanced Brightness Booster Max algorithm – for a stunning picture, from any angle, in any light environment. The award-winning webOS smart platform offers a huge range of easy-to-search streaming services, and you can control it by voice with Alexa built-in. It comes with the flush-fit wall mount built in, and does not include a tabletop stand.

4K OLED Screen
The pixels of the Organic LED display are self-illuminating, adjusting independently, for true depth and colour gradation. This 4K OLED screen produces impeccably deep blacks, bright whites, and scintillating colour. This revolutionary technology has been mastered by LG for stunning picture quality, and from any angle.

4K UHD resolution with Dolby Vision HDR
This screen has four times the number of pixels than Full HD TVs, delivering stunning realism, natural motion and incredible detail. High Dynamic Range expands light, dark, and every colour in between for a picture that's closer to real life. This set supports multiple HDR formats including Dolby Vision.

Zero Connect Box
Connect your devices, such as games console or set-top box, to the separate Zero Connect Box, and it wirelessly transmits high quality pictures (at up to 4K 120Hz) and premium sound to the TV, even when placed up to 10 metres away from the screen. So you can place your devices where you want in your room, and enjoy easy access to the ports.

One Wall design
The M3 offers an ultra slim profile and built-in flush fit wall mount providing understated elegance, merging seamlessly into the environment while making a bold statement. It comes with a built-in flush fit wall mount, and does not include a tabletop stand.

a9 Gen6 AI processor
LG’s advanced processor, the brain of the TV, is made for OLED, ensuring premium picture and sound quality, and delivering image enhancement through AI Super Upscaling. Plus, it upscales audio too for a more cinematic experience.

Extraordinary cinema, hyper-real sports experience

Dolby Vision plus Dolby Atmos sound

webOS smart platform
LG’s award winning webOS platform hosts a huge variety of the top streaming services, including Freeview Play, NOW, Netflix, Prime Video, Disney+, Twitch, and more.* Browsing and searching is super simple, Quick Cards make it easy to search based on your interests, and you can control it with your voice with built-in Alexa.

LG soundbar synergy
When paired with a compatible LG soundbar (sold separately), you can enjoy an enhanced sound experience with seamless pairing. The WOW Orchestra feature utilises TV and soundbar speakers simultaneously, and you can control the soundbar with the TV remote.

Please note: this TV is designed to be installed flush to the wall using the included mount. Therefore any plug socket or aerial cable directly behind the TV would need to be recessed into the wall.

Perfect partners
With TVs getting slimmer and built-in speakers getting smaller, choosing the right sound system is more important than ever. Soundbars enhance your TV's sound quality and add that extra audio punch to all your movies, games and TV programmes. More affordable and easier to set up than a full size speaker system, they don't compromise on quality either.

Don't forget...
If you want to connect your TV to a blu-ray player, games console, soundbar or soundbase then you'll need a HDMI cable.
