PRODUCT OVERVIEW

251441: SCREW,CAP,HEXAGON HEAD.

4K HDR : Enhanced Contrast, Colours and Finest Details The latest standard for 4K UHD content is High Dynamic Range. It expands the range of both contrast and colours significantly. HDR reproduces accurately light and dark shades with precise colours and dazzling detail images.

SMART HDR both improves native HDR and converts SDR to HDR. 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 rat This part is cataloged in the U.S.

Government catalog under NSN 5305-00-269-2816, indicating validated use in U.S. government and defense logistics supply chains.
