Lol, while it's nice of you to try to clarify, but you gotta make sure you're giving out the right info. There is no 780p, and the highest tv format right now is 1080p.It's either 1920x1080, or a scaled proportion of that ratio to 1280x720p. P means every horizontal line of what's displayed is actual image data, "i" is interlaced, meaning every other line is actual image data.
LOL right back at you
The point was that some are assuming that a phone screen must have 720 pixels and not the iPhone 640pixels to get high resolution for movies on a phone display. It is wrong to take a tv's 720p standard and apply it to the pixel count on a phone display.
You want to focus on ppi and the aspect ratio of 16:9
PS: it's 1080i not 1080p.
http://en.wikipedia.org/wiki/720p
720i (720 lines interlaced) is an erroneous term found[citation needed] in numerous sources and publications. Typically, it is a typographical error in which the author is referring to the 720p HDTV format.[citation needed] However, in some cases it is incorrectly presented as an actual alternative format to 720p.[3] In fact, no proposed or existing broadcast standard permits 720 interlaced lines in a video frame at any frame rate.[4]
