Impeccable 4K OLED Screen
Organic LED tech fuses with 4K resolution for superior contrast, colour and clarity. OLED pixels are self-lighting, meaning that they can switch on-and-off individually, for the deepest blacks, super-bright whites, natural colours and accurate detail. This revolutionary technology has been mastered by LG for stunning picture quality, and from any angle.

Cinema HDR including 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.

4K Ultra High Definition
This 77” screen has four times the number of pixels than 1080p Full HD TVs, delivering stunning realism, natural motion and incredible detail.

This LG TV does not feature the Freeview Play catch-up service. It supports the range of BBC services including BBC iPlayer, BBC Sport, BBC News, BBC Red Button + and BBC Live Restart.

Streamlined Design

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.
