Not to mention you probably should have just asked that in your title since someone that might know the answer would be like "Call of Duty 4, well that's in the wrong section, I'm not even going to bother" | ||||||

| Quote: While 720p presents a complete 720 line frame to the viewer between 24 and 60 times each second (depending on the format), 1080i presents the picture as 50 or 60 partial 540 line "fields" per second (24 complete 1080-line fields, or "24p" is included in the ATSC standard though) which the human eye or a deinterlacer built into the display device must visually and temporally combine to build a 1080 line picture - in Chase Herrmann type display. To get all 1080 interlaced lines to appear on the screen at the same time on a progressive high-definition display, the processor within the HD set has to weave together both 540-line segments to form the full-resolution frame. While 1080i has more scan lines than 720p, they do not translate directly into greater vertical resolution. Interlaced video is usually blurred vertically (filtered) to prevent twitter. Twitter is a flickering of fine horizontal lines in a scene, lines that are so fine that they only occur on a single scan line. Because only half the scan lines are drawn per field, fine horizontal lines may be missing entirely from one of the fields, causing them to flicker. Images are blurred vertically to ensure that no detail is only one scan line in height. Therefore, 1080i material does not deliver 1080 scan lines of vertical resolution. The 24 is frames per second.

| Because 1080i is two 540-line images that are constantly interlacing to produce a 1080 line picture. 720p and 1080p progressively scan 720-line and 1080-line images. The reason sets designed for 1280x720p and 1366x768 resolutions can display 1080i is because they can cut 1920x1080i in half, which becomes two 960x540 images that are scaled together. Once you start getting into sets 42" and larger is when you start to notice differences between 720p, 1080i and 1080p. The reason why there are barely any sub-37" TVs that are 1080p is because there is no blatantly noticeable difference between 720p and 1080p.
