HDR powered by HDR10+
Samsung are one of the forerunners of contrast and colour-boosting High Dynamic Range (HDR). As members of the UHD Alliance, they've delivered top-shelf HDR to deepen your view and show 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. Driven by their UHD engine, Samsung's HDR powered by HDR10+ gives a glorious glow that will knock your socks off.
4K Ultra High Definition
To respond to screens getting bigger, brands have packed their screens with more pixels. This 43” screen has four times the number of pixels than 1080p Full HD TVs, delivering stunning realism, natural motion and incredible detail. And UHD upscaling increases the clarity of non-4K content.
Dynamic Crystal Colour: with over a billion hues the picture is stunningly accurate to the colours of real life.
Auto Motion Plus: Experience smooth action on fast-moving content; great for enhancing action movies or live sports events.
UHD Dimming: adjusts tone, brightness, and sharpness independently for brilliantly accurate contrast, shadow detail, and colour.
Gaming: with this smart feature, play world famous streaming & PC games on your TV with cloud gaming services.*

360 Design with Clean Cable Solution and One Remote
Minimalistic Charcoal Black 360 Design looks stunning from any angle, with a clean back panel, for an eye-catching look that enhances any viewing setting. In keeping with the elegant aesthetic, connecting cables run down through legs of the stand, removing unsightly clutter from your living room and complementing a supremely refined look. And with Samsung's handy One Remote, you can control all compatible devices for seamless multi-tasking.
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.
