4K recording refers to a video resolution that offers approximately 4,000 pixels across the horizontal axis. This high-definition format provides four times the detail of 1080p, resulting in sharper images and more vibrant colors. It is commonly used in television, cinema, and video games to enhance the viewing experience. The term "4K" can also refer to the aspect ratio of 16:9, which is standard for most screens. To enjoy 4K content, viewers need compatible devices, such as 4K TVs or monitors, and high-speed internet for streaming. This technology has become increasingly popular due to its ability to deliver stunning visual quality.
