8K is a display resolution of 7680 x 4320 pixels, which is four times the resolution of 4K, or Ultra HD. 8K displays offer even higher resolution and more detailed images than 4K displays, providing an even more immersive viewing experience. However, 8K technology is still in its early stages, and there is currently limited 8K content available. In addition, 8K displays are generally more expensive and require more powerful hardware to support the higher resolution and frame rates. As a result, 8K is not yet widely adopted, but is expected to become more common in the future as the technology and content availability improve.
