What is 4K60 mean?
4K60 refers to a specific video resolution and frame rate combination, where 4K denotes the resolution of approximately 3840 x 2160 pixels (also known as UHD or Ultra High Definition), and 60 indicates a frame rate of 60 frames per second (fps). This means that the display can show 60 distinct images every second at this high resolution, resulting in smoother motion and enhanced visual clarity compared to lower frame rates.
Key Components of 4K60
- Resolution (4K): The term "4K" typically refers to a horizontal pixel count of around 4000. In consumer electronics, it is commonly associated with a resolution of 3840 x 2160 pixels, which provides four times the pixel count of Full HD (1080p) and delivers significantly sharper images23. True cinema 4K, defined by the Digital Cinema Initiatives (DCI), has a resolution of 4096 x 2160 pixels5.
- Frame Rate (60 fps): The "60" in 4K60 indicates that the video is displayed at 60 frames per second. This higher frame rate is beneficial for fast-moving content, such as sports or action films, as it reduces motion blur and provides a more fluid viewing experience14.
Bandwidth Requirements
To support uncompressed 4K60 video, significant bandwidth is required. For instance, uncompressed 4K60 with full color (4:4:4 chroma subsampling) necessitates around
12 Gbps of bandwidth4. This high demand for data transmission can pose challenges for distribution over standard networks unless advanced technologies are employed.
In summary, 4K60 signifies a high-resolution video format that combines ultra-high-definition visuals with a smooth frame rate, making it ideal for modern displays and media consumption. This combination enhances the viewing experience by providing detailed imagery and fluid motion.
