key term - 3840x2160

Definition

3840x2160 is a resolution standard commonly known as 4K or Ultra High Definition (UHD), representing the number of pixels displayed on a screen, with 3840 pixels horizontally and 2160 pixels vertically. This resolution offers four times the pixel count of Full HD (1920x1080), leading to significantly sharper images and greater detail, especially on larger screens. The increased pixel density enhances the viewing experience, allowing for more immersive content that is crucial in modern digital television broadcasting.
