1080p vs. 1080i
Progressive scan is used for most cathode ray tube (CRT) computer monitors, all LCD computer monitors, and most HDTVs as the display resolutions are progressive by nature. https://en.wikipedia.org/wiki/Progressive_scan
Interlaced video (also known as interlaced scan) is a technique for doubling the perceived frame rate of a video display without consuming extra bandwidth. https://en.wikipedia.org/wiki/Interlaced_video
1080i (1920×1080) interlaced scan: 1,036,800 pixels (~1.04 MP). 1080p (1920×1080) progressive scan: 2,073,600 pixels (~2.07 MP).
