Product description

Product code: 82431003

Panasonic’s MX800 4K HDR Fire TV is built for performance and all-in-one convenience. The HDR Bright Panel Plus screen delivers natural brightness and colour, boosted by multi-HDR support including Dolby Vision, and all driven by the brand’s HCX Processor. Dolby Atmos and Surround Sound make the audio just as immersive as the picture. Choose from a host of streaming services using the brilliantly simple-to-use Fire TV platform, use Alexa voice control to easily find your favourites, and even get personalised recommendations.

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.


  • HCX Processor: the brain inside this model delivers spectacular levels of contrast, clarity, and accurate colour.
  • HDR Bright Panel Plus: produces a wide range of colours for a natural picture.
  • Dolby Atmos: immersive Dolby Atmos audio envelopes you in 3D sound, so you can feel like you’re in the best seat in the sports stadium, or at the very heart of the cinematic action.
  • Surround sound: opens up the soundstage to make the soundtrack feel as involving as the action itself.
  • Game Mode: reduces input lag, so the on-screen action reacts instantly to your gaming controls, taking you from the sofa into the game-world.
  • Fire TV
    Amazon’s Fire TV platform is so user-friendly. With the supremely simple-to-use Fire TV home screen, you can easily search across multiple streaming services, including channels and apps, to find what you’re after (Amazon account required).*

    Alexa built-in
    This Panasonic TV has Alexa built-in, so you can so you can change channel, adjust volume, and more, with just your voice.

    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.
    Take a look at our full range of soundbars.

    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.
