Огненное представление в Сидней, Австралия! High definition meant 1080p (1,920 by 1,080) resolution for years, but it’s quickly being overtaken by ultra high definition television, commonly called 4K. It’s technically UHD according to the Consumer Technology Association, but the two terms are interchangeable. They also matter matter a lot to your television buying decisions, since 4K is finally a mature, accessible technology. What Is 4K? A UHD or 4K display is one with at least 8 million active pixels. For televisions, that resolution has standardized to 3,840 by 2,160. Digital cinema 4K (the resolution in 4K movie theaters) is slightly higher at 4,096 by 2,160. However you define it, it’s four times the number of pixels on a 1080p display, and over 23 times the resolution of standard definition television.
