"4K" refers to a display resolution of approximately 4,000 pixels across the horizontal axis. This resolution is typically 3840 x 2160 pixels for consumer televisions and monitors, providing four times the detail of the standard 1080p resolution. The increased pixel count allows for sharper images and more vibrant colors, enhancing the viewing experience for movies, video games, and other visual content. The term "4K" is often associated with Ultra High Definition (UHD) technology, which is used in modern televisions and streaming services. Many cameras and video production tools now support 4K recording, making it easier for content creators to produce high-quality visuals. As 4K technology becomes more common, it is increasingly available in homes and theaters worldwide.
