A 4K TV provides rich colours, high contrast and exceptional detail to provide excellent home entertainment. Ultra High Definition (or UHD) packs up to four times the number of pixels of a high definition TV onto the screen. Eight million pixels mean that your TV delivers truly stunning detail and depth with vibrant colour and fine textures. As the on-screen action won't suffer as you move closer, you can sit slightly closer to the screen to immerse yourself in your entertainment.
What is 4k?
High Dynamic Range explained
Many new Ultra HD TVs feature High Dynamic Range (HDR) - this superior standard of content aims to display colours as closely to real life as possible. HDR delivers a wide range of accurate colours, as well as brighter whites and deeper blacks for better contrast. Not only does this keep colours true-to-life with blended tones, but it also adds to the on-screen detail, letting you pick out detail in shadows.
