4K Video refers to a resolution of approximately 3840 x 2160 pixels, which is four times the pixel count of 1080p resolution. This higher pixel density results in sharper images and more detailed visuals, making it ideal for large screens and immersive viewing experiences. The term "4K" is commonly used in the context of television, streaming services, and cinema. Many modern devices, including smart TVs and cameras, support 4K video, allowing users to enjoy high-quality content. As technology advances, 4K has become increasingly popular among consumers and content creators alike.
