4K resolution refers to a display resolution of approximately 4,000 pixels across the horizontal axis. Specifically, it typically measures 3840 x 2160 pixels, which is four times the resolution of 1080p (1920 x 1080 pixels). This higher pixel count allows for more detailed and sharper images, making it ideal for large screens and immersive viewing experiences. The term "4K" is commonly used in the context of televisions, monitors, and projectors. It enhances the clarity of movies, video games, and other visual content. As technology advances, 4K content is becoming more widely available through streaming services and physical media, providing viewers with a richer visual experience.
