Panasonic’s HX820 TV features their HDR Bright Panel Plus screen for an exceptional 4K HDR picture. With multiple HDR support, Hollywood picture tuning and Local Dimming tech, this slimline TV delivers superb picture detail and highly accurate contrast. Dolby Atmos sound is spatial and immersive to complete the cinematic experience. Its customisable Smart Platform brings you a wealth of online apps, including streaming services Netflix and Amazon Prime Video*, and it works with compatible voice assistant smart devices.
HDR with Dolby Vision and HDR10+
High Dynamic Range 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. Panasonic’s HDR Bright Panel Plus supports multiple HDR formats including Dolby Vision, HDR10+ and HLG so you'll always get the full HDR treatment.
4K Ultra High Definition
This 58” screen has four times the number of pixels than 1080p Full HD TVs, delivering stunning realism, natural motion and incredible detail.
HCX Processor: with Hollywood picture tuning, Panasonic’s Hollywood Cinema Experience processor gives blacker blacks, whiter whites, lustrous contrast, and a wider colour range that does true justice to the film-makers' vision. Panasonic’s know-how with colour, black and brightness levels comes from years of manufacturing reference quality OLED and Plasma TVs, as well as pro broadcasting equipment.
Dolby Atmos Sound: get more immersed in your entertainment’s audio with the cinematic, three-dimensional sound placement of Dolby Atmos.
Bluetooth Audio Link: connect easily to a wireless Bluetooth speaker to provide additional sound with no need for cables. And it works the other way, you can wirelessly link your smart device to play music wirelessly through the TV’s speakers.
Local Dimming: adjusting light output in different areas of the screen independently gives deeper blacks contrasted with brilliant luminance.
Intuitive Smart Platform
‘my Home Screen 5.0’ provides quick and intuitive access to the content you want, with a huge variety of apps on a customisable home screen. Regular updates keep it up-to-date with the latest technology and content developments.

Works with your Smart Assistant
This Panasonic TV works with both Google Assistant and Alexa devices, so you can change channel, adjust volume, and more, with just your voice, using compatible smart speakers and devices.
Freeview Play combines catch-up TV, on-demand services and live television, so 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. This gives effortless scroll back so you never miss a second of your favourite shows.
Framed with a slim bezel, this TV's refined looks are sleek and stylish.
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.

If you want to connect your TV to a blu-ray player, games console, soundbar or soundbase then you'll need a HDMI cable.
