4K Cinema HDR with Dolby Vision
HDR deepens your view and shows shades previously unseen in home entertainment. Expanding light, dark and every colour in between to extraordinary new levels, this model's picture gets closer to real life. LG's 4K Cinema HDR supports multiple HDR formats including Dolby Vision, Advanced HDR by Technicolor and HDR10 Pro.
4K Ultra High Definition
This 55” screen has four times the number of pixels than 1080p Full HD TVs, delivering stunning realism, natural motion and incredible detail.
NanoCell Display: LG's NanoCell technology means each individual pixel is only one nanometre apart for impeccable colour precision and volume, for outstanding picture quality, viewed from any angle.
Full Array Local Dimming: Dimming zones independently throughout the entire screen expands the contrast range. More back light control gives deeper blacks and brighter whites across the full image.
Alpha 7 Gen 2 Processor: The second generation intelligent processor is optimised for LG’s NanoCell screen, for a premium LED picture of exceptional clarity and brightness, whatever you’re watching.
Dolby Atmos Sound: immersive Dolby Atmos places sound within three dimensions for an enveloping soundscape, with you at the centre. Coupled with Dolby Vision HDR, it's a fully cinematic experience.
Thinq AI: bringing the intelligence and convenience of voice interaction to the living room, this Thinq AI TV can listen, think and respond to your questions.
4K High Frame Rate via HDMI : With full HDMI 2.1 compatibility, this LG TV can handle High Frame Rates for smoother motion, so even the most frantic sporting action is crisp and blur-free.

Advanced Voice Control & Smart Compatibility

You can also control compatible smart devices, and check your Google photos or Google Calendar on the TV screen (Google sign-in required). It’s also compatible with Apple Airplay 2 and Homekit devices.
This LG TV features Freeview Play. Combining catch-up TV, on-demand services and live television, watching what you want, when you want, is now easier than ever. It’s free from subscription and is compatible with existing broadband services too. Services such as BBC iPlayer, ITV Hub, All 4 and My5 are also available without having to open specific applications.

Cinema Screen Design
Finished with an elegant crescent stand, the harmonious design of this TV’s Nano Bezel maximises the viewing area and enhances the TV watching experience.
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.
Take a look at our full range of soundbars.
If you want to connect your TV to a blu-ray player, games console, soundbar or soundbase then you'll need a HDMI cable.
