- Ultra UHD Certified
Marvel at the glorious, colour-rich detail of the HDR 4K UHD picture with Samsung's MU6400. Active Crystal Colour tech achieves a staggering array of luscious colour. See every detail in a glorious sunset, witnessing amazing brightness and contrast for a beautifully lifelike picture. Access a world of online entertainment via Samsung's Smart Hub, and control all compatible devices via one remote control. The spectacular visuals of the MU6400 will revolutionise your home viewing.
HDR with Active Crystal Colour
Samsung are one of the forerunners of colour-boosting High Dynamic Range (HDR). As members of the UHD Alliance, they've engineered HDR heightened by their Active Crystal Colour technology. This tech delivers over 17 million colours and a 20% wider colour space than conventional UHD. This makes shades sharper, the image deeper, and colours endlessly rich. Plus the screen's UHD Dimming achieves more realistic shadow detail and contrast too. Being able to independently adjust tone, brightness and sharpness in different areas around the screen gives a stunningly realistic picture quality.
4K UHD with Upscaling
The MU6400's Certified Ultra HD 4K resolution screen takes you to the next level of viewing experience. Four times the number of pixels of 1080p Full HD delivers stunning realism, natural motion and incredible detail. Experience this high-spec picture on everything you watch thanks to 4K upscaling. Samsung's innovative upscaling technology converts lower resolution content to a level of detail near UHD. Upscaling is a process through which a lower resolution signal or data source is displayed at a higher resolution. The upscaling process interpolates additional pixels from the source data, and produces a clearer picture on your 4K screen than a non-upscaled image. Meanwhile the brand's Auto Motion Plus processing ensures even the very fastest action, like sports or action movies, is always smooth and blur-free.
Ultra Clean View
Give your old favourites a sparkling makeover with Ultra Clean View. This clever tech analyses the input signal and reduces distortion and visual noise. So no matter what the content, it'll always be a ravishing picture of crispness and clarity.
Samsung Smart Hub
Now faster, with ultra-high definition streaming, catch-up and games services, is the latest Smart Hub platform. This quick and easy platform marks a massive step forward for the connected home. Access the latest apps to experience the best UHD content from Netflix and Amazon*. You can even browse content easily, searching for your favourite programmes and movies while you are still watching TV. Powering the seamless interaction is the powerful Quad Core processor which significantly boosts performance with faster access to Smart features. Enjoy super-fast response times, as you use and toggle between apps, online services and live TV with ease. You can even use voice control by engaging S Voice on the remote.
Get rid of the clutter of multiple controls. The Samsung One Remote can control all your compatible devices for seamless multi-tasking. So with compatible components you can switch channels on your set-top box, adjust the volume on the sound bar, or surf the web on the big screen, all via one controller.
Experience easy access to the latest movies via your TV guide in addition to all your traditional TV channels. Whether you’re browsing for the latest Hollywood blockbuster or trying to find Ultra HD content, expand your viewing options through a wealth of additional Smart channels with Samsung TV Plus. Watch subscription free content with on-air and catch-up services (charges apply for premium on-demand content).
Music: With this smart feature, instantly recognise and listen to any background music.*
TV Sound Connect: Effortlessly connect a Samsung soundbar to your TV with Soundconnect.
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.
