What is the difference between HD and Full HD?

  • HD, or "HD-ready", is known as 720p and has a resolution of 720 lines vertically and 1280 picture elements horizontally. The letter “p” stands for progressive scan, which means that the lines of each frame are drawn in sequence. The frame rate is 24 frames per second.
  • Full HD, also known as 1080i, is a video format with a staggering 1,080 lines of vertical resolution, and 1920 picture elements in the horizontal direction. The letter “i” stands for interlaced scan, which means that the lines of each frame are drawn interlaced. Each frame consists of 1920 × 1080 pixels — some two million pixels in total, with a widescreen aspect ratio of 16:9. The frame rate is 50 frames per second.
