4K

4K refers to a resolution standard used in digital television, digital cinema, and other forms of digital media. The term "4K" denotes a horizontal display resolution of approximately 4,000 pixels. In the most common implementation, known as Ultra High Definition (UHD), the resolution is 3840 x 2160 pixels, which is four times the pixel count of Full HD (1920 x 1080). The increased pixel density allows for greater detail and clarity in images, especially on larger screens. 4K is often used in high-end televisions, streaming services, and video production, providing a more immersive viewing experience due to enhanced visual quality, improved color depth, and better image sharpness. Additionally, 4K content may include higher frame rates and improved dynamic range, further elevating the visual experience.
