A 4K monitor is a display device that offers a resolution of 3840 x 2160 pixels, which is four times the resolution of a standard 1080p monitor. This higher pixel count results in sharper images and more detailed visuals, making it ideal for activities like gaming, video editing, and graphic design. In addition to improved clarity, many 4K monitors support advanced technologies such as HDR (High Dynamic Range) for better color accuracy and contrast. They are increasingly popular among professionals and enthusiasts who seek an enhanced viewing experience for both work and entertainment.
