Product information

Enjoy a brilliantly vibrant 4K HDR picture with Samsung's MU6120. The brand's Certified Ultra HD screen delivers an image of beautifully true colour and clarity. Auto Depth Enhancer technology takes you further into the visuals, while 4K upscaling and Ultra Clean View features ensure whatever you're watching gets the same sparkling 4K treatment. Access a world of online entertainment via Samsung's Smart Hub too. The spectacular visuals of the MU6120 bring a world-class viewing experience into the home.

HDR with Auto Depth Enhancer
Samsung are one of the forerunners of colour-boosting High Dynamic Range (HDR). As members of the UHD Alliance, they've delivered top-shelf HDR. This means that there are over a billion individual colours to deepen your view and show shades you’ve never seen in home entertainment before. Usually, studios are forced to dilute the colour of their shows and films to fit on our TVs. Now, HDR screens like the MU6120 can channel content from studio-to-living room with the same precision and utterly otherworldly hues. 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. And it's all heightened by the brand's Auto Depth Enhancer which maximises your immersion in the picture.

4K UHD with Upscaling
The MU6120'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.

Samsung TVPlus
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).

Other Features:

Music: With this smart feature, instantly recognise and listen to any background music.*

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.
