An improved color reproduction and significantly more gradations for an expanded color spectrum: This allows you to experience vibrant details in bright colors, more naturally than ever before! HDR (High Dynamic Range) on your television is the innovation. Thanks to metadata for brightness control, your TV always knows exactly how bright each area of the image should be displayed. The result is the best contrast values and incredibly realistic images like you have never seen before. The Smart Hub is the brain of your TV. It simplifies the control of your television and helps you quickly and easily find exciting content. Countless apps, such as Netflix, YouTube, and HollyStar, give you access to a vast world of thrilling entertainment. Ultra HD – short for UHD or 4K – is the future of television. The very high resolution of 3840 × 2160 pixels is the best you can currently see. And when sources do not have a UHD resolution, Samsung upscales to UHD level. This way, you can enjoy detailed and razor-sharp images every day.
