The term “4K Ultra HD” (also known as 4K Ultra High Definition, 4K UHD, or just 4K) refers to the resolution of the TV, which is a measure of how much detail you can see on the screen. The resolution of a traditional 1080p Full HD TV is limited to 1,920 columns and 1,080 rows of pixels, while a 4K Ultra HD TV has an increased resolution of 3,840 columns and 2,160 rows of pixels. With four times the resolution of 1080p, 4K Ultra HD offers improvement in picture clarity over existing HD resolutions.
