	GameSpot Forums - Xbox 360 - 720p - 1080i Which is better? : /
		I would imagine 1080i is because its greater, but i have heard differently.
		Okay, 1080i is better, because its a clearer resolution. Assuming you tv can handle 1080i, use it. Otherwise, use 720p.
		1080i is just higher resolution (which you'd think would be cleaner, but it isn't that simple).

	HDTV Buyer Beware (Site not responding. Last check: 2007-10-17)
		From a 1080i HDTV show, every (approx.) 1/60'th of a second a field of 540 scan lines is received, first a field of all of the odd lines and then a field of all of the even lines.
		Scan lines for each incoming 1080i field, whether from an odd field or an even field, would be inserted into the same 540 unique vertical positions in the frame and the 180 gaps would always be in the same places.
		As in the 1080i to 720p conversion, the drawback to this method is that blurring is more noticeable if subject motion has occurred relative to the two fields in question.

	Isn't 1080i REALLY just 720i on MOST HDTVs? - Beyond3D Forum
		1080i is a resolution of 1920 X 1080, but displayed interlaced (so 1920 X 540 per refresh).
		Pretty much ANY HDTV you look at will have the 1080i sticker on it, but you look a little closer, and you'll find that the actualy resolution of that HDTV is 1280 X 720 (or someting close, such as 1366 X 768).
		It seems like you may be a bit confused on what exactly interlacing is. 1080i and 540p are not the same thing.

	People who have 1080i native, 720p supported - PS3Forums (Site not responding. Last check: 2007-10-17)
		I have a 1080i crt that also supports 720p so I was originally told that it would work with the ps3 since it supported 720p.
		My tv is natively 1080i with user selectable 540p but it also supports (not displays) 720p so i thought i wouldn't have this problem but according to what this guy said even if it says it supports 720p it doesn't work.
		So, HD signals in 1080i looked great on those units but 720p (even though it's "supported") were downscaled in the TV to 480p (that's the only way to display 720p on them).

	HDV - Wikipedia, the free encyclopedia
		HDV 1080i uses a pixel resolution of 1440×1080, but when displayed is scaled to an aspect ratio of 1920×1080 = (1440 × 1.33)×1080.
		Despite using "only" 1440×1080 pixels for 1080i, the perceived sharpness with HDV is much higher than that of PAL or NTSC DV formats.
		In total 1080i has a resolution of 1,555,200 pixels, which is 4.5 times larger than the resolution of NTSC DV (345,600 pixels) and 3.75 times larger of PAL DV (414,720 pixels).

		1080i, the former king of the HDTV hill, actually boasts an identical 1,920x1,080 resolution but conveys the images in an interlaced format (the i in 1080i).
		In a tube-based television, otherwise known as a CRT, 1080i sources get "painted" on the screen sequentially: the odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines--all within 1/30 of a second.
		Progressive-scan formats such as 480p, 720p, and 1080p convey all of the lines of resolution sequentially in a single pass, which makes for a smoother, cleaner image, especially with sports and other motion-intensive content.

	Guide to 1080i DVI on Radeons - AVS Forum
		A custom 1080i resolution uses the same total timings as the standard resolution so that the HDTV sees it as 1080i, but it has fewer "Active pixels" and is seen by Windows as a lower resolution.
		As with 1080i, you may find that your HDTV sometimes is unable to pick up the interlaced signal from the ATI card — particularly immediately after starting Windows or when the input source on the HDTV has been switched away from the DVI or HDMI port connected to the PC.
		Also to note 1080i althought handy at times when browsing the web, is a bit on the flickery side if you have a quick eye, also non HD movies look terrible, even with ffdshow in full effect.

	1080i vs. 1080p HDTV: should you care? - Fully Equipped - CNET reviews
		Today's high-def broadcasts are done in either 1080i or 720p, and there's little or no chance they'll jump to 1080p any time soon because of bandwidth issues.
		Meanwhile, some newly announced DVD players from Denon and NeuNeo (who?) are claiming to upconvert standard DVD movies to 1080p resolution, but that's a far cry from native high-def content.
		Comparing a 50-inch 1080p DLP set to a 50-inch 720p DLP set, for example, he says you'll be hard-pressed to notice more detail with 1080i sources, especially from farther than 8 feet away.

	1080i on component, 1080p on HDMI - Blu-ray Forum
		1080i is a higher bandwidth as it's 19201080{50/2 or 60/2} which is marginally higher than 1080p/24.
		I wouldn't put it past Sony to line double their 540 component video output to display 1080i so that they could market it as 1080i even though it would have half the detail of a true 1080i signal.
		In this case, if a movie was a allowed to display 1080i by the studio, you would see a true 1080i signal (1080p converted to 1080i).

		I understand that a 1080i input to the 400q bypasses its internal scan converter, so I'm not sure why my picture geometry isn't right (faces are too narrow).
		What is bypassed, is the projectors controls for most picture settings, aspect ratio, etc. With 1080i input the sync width of the input signal must match what the 400Q expects, for the picture to have proper geometry.
		It sounds like some folks have successfully managed to set up 1080i input to their 400q and are very pleased with the picture vs standard resolution.

		This rendered 720p is upconverted internally to output 1080i or 1080p.
		1080i has 30 different frames, and these are interlaced (split in half if you will), and flashed on the screen fast enough that your brain combines them into full frames.
		In this case, the only difference between 1080i and 1080p is where the de-interlacing is done.

	IGN Boards - 1080i vs 720p
		But 720p is better, only because 108i runs interlacing the images(hence the i), and the 720p runs progressively(hence the p), so the interlaced image can have the tendency to chop up a bit/blur becasue the images aren't tunning as smooth as progressive.
		1080i looks a bit better on my tv, but I set it to 720p for games and 1080i for movies.
		The reason why 1080i isn't as good at some points is that it sends half the picture at a time, one frame the odd lines and the next the even lines.

		So if it changes from 420p to 720p or to 1080i my tv switches to the appropriate resolution, Same thing happens when I change the resolution setting on the 360 my tv switches to the same setting.

	HDTVexpert — Front Line: 1080P — Time for a Reality Check!
		All kinds of compromises are made in the acquisition, production, and transmission of 1080i content, from cameras with less than full resolution in their sensors and reduced sampling of luminance and chrominance to excessive MPEG compression of the signal as it travels from antenna, dish, or cable to your TV.
		To show a 1080i signal, many consumer HDTVs do the conversion from interlaced to progressive scan using an economical, “quickie” approach that throws away half the vertical resolution in the 1080i image.
		The bandwidth is barely there for 1080i channels, and it’s probably just as well, because most TVs wouldn’t support 1080p/60 anyway — they’d just convert those signals to 1080i or 540p before you saw them.

		a) 1080i HDTV films correctly encoded at 24fps, with repeat flags to play at 1080i/60 on set-top players, which TheaterTek wonderfully decodes to 1080p/24 so deinterlacing is not required.

		For these a simpler solution is I often use a Roku HD1000 1080i/60 set-top networked player, or could take time to author and burn on to an HD DVD, which can play at 1080i/60 (I use a Toshiba HD-A1 for it's 1080i/60 HDMI output).
