Understanding TV resolutions: 720p, 1080p, 4K, and 8K explained

4K resolution, also known as Ultra HD, is standard on most new TVs 50 inches and larger, offering 3,840x2,160 pixels. This resolution provides four times the pixels of 1080p (Full HD), resulting in sharper images. While 8K TVs exist, 8K content is scarce, making 4K the current practical standard for high-quality viewing. Other resolutions like 1080p and 720p are still found on smaller or older TVs, and computer monitor resolutions use different naming conventions. Picture quality also depends on factors beyond resolution, such as contrast and color.
