4K resolution refers to display resolutions with a horizontal count of approximately 4,000 pixels. The Consumer Technology Association (CTA) developed the 4K UHD standard, which was ratified by the International Telecommunication Union (ITU) as part of the Ultra High Definition (UHD) standard. OLED and LCD are display panel technologies capable of producing high pixel counts for 4K, and H.265 (HEVC) is a video compression codec used for 4K content. Netflix and Amazon Prime Video offer a significant portion of their libraries in 4K. Major Hollywood studios like Warner Bros. and Paramount Pictures are part of the Digital Cinema Initiatives (DCI). Sony, Samsung, and LG were early adopters and major manufacturers of 4K displays, while Intel and Nvidia developed processors capable of handling 4K data processing demands. PlayStation 5 and Xbox Series X consoles prioritize 4K output. High Dynamic Range (HDR) expands the range of colors and contrast for an enhanced viewing experience, with Dolby Vision and HDR10+ being formats that enhance 4K viewing. Live broadcasting in 4K is becoming more common for major sporting events like the Olympic Games.
