The latest standard for 4K UHD content is High Dynamic Range. It expands the range of both contrast and colour significantly. HDR reproduces accurately light and dark shades with precise colours and dazzling detail images. With HDR content and sources being yet to reach heights of popularity, SMART HDR upgrades Standard Dynamic Range (SDR) content to HDR-like picture quality, allowing viewers to enjoy all of their favourite content in the highest picture quality possible. Additionally, on native HDR content, SMART HDR dynamically improves content and adapts it to the screen capabilities. Through AI and HDR scene identification, SMART HDR improves both dark and bright scenes. On dark scenes, it supplements the level of brightness to express objects hidden in darker shadows. On brighter content scenes, SMART HDR increases the level of contrast ratio to differentiate objects from the background. It makes the picture more layered and rich, resulting in more image details on the screen for an overall better lifelike picture. Micro Dimming analyses the TV picture in around one hundred separate zones to adapt the brightness. Picture quality is significantly improved for an exceptional visual experience, especially in the dark.
