  720p   (Site not responding. Last check: 2007-09-08)
720p is directly compatible with newer flat panel technology such as plasma and LCD which are inherently progressive and must perform deinterlacing to display 1080i source material.
The 720p system was tested against competing standards during FCC trials, and was particularly notible for its lack of flicker and shimmer of moving edges.
The main tradeoff between the two is that 1080i may show more detail than 720p for a stationary shot of a subject at the expense of a lower effective refresh rate and the introduction of interlace artifacts during motion.

 1080p to 720p downscaling. - PS3Forums
If the 720p render throws away detail that is mainted in the 1080p render and the detail also “survives” the downscaling, than the downscaled image can have more detail.
It’s very possible that a 720p render will “throw away” or to put it in another way, choose not to try and render the thinnest lines because they are much smaller than the 720p pixels.
Instead of a white pixel the render would render a light-grey pixel (as in my figure) and the native 720p line will be more accurate than the 1080p-to-720p downscaled line, but obviously this is much more demanding compared to if the rendered had filtered out the thin lines.

 HDTVoice.com - High-Definition Television Talk - How important is 720p?
720p is a good mode but adds costs to implement it natively, much cheaper/easier to upconvert.
Many of them "support" 720p, but when you read the manual, you'll find a sentence buried somewhere that informs you that the set will not display it, but instead down-converts it to 480p.
720p is a higher resolution than most folks' 1080i, even considering the horizontal resolution.

 720p and 1080i - Henninger Media Services
I'll get great flames for saying all of that because there are arguments about 720p having just as many pixels per second as 1080i, so the picture is just as good for pixel count plus has the advantage of being progressive scan.
The progressive scan system has advantages over interlace in that each frame is a complete frame with all the pixels present and it refreshes 60 times a second.
They won't show you the differences between the current 720p and 1080i and it's wrong to judge video systems on displays that can't show the difference.

 Xbox.com | Australia - 720p v 1080 p   (Site not responding. Last check: 2007-09-08)
I was reading a comment from a MS tech that said that 720p was more than adequate for games, and that the sacrifices needed to run in 1080p may actually make games look worse (sorry, don't have a link!).
I personally think 720p looks better then 1080i, but i agree in some games 1080p is not YET possible but i can see Halo 3 and the next Resistance Fall Of Man game being 1080p because they will be albe to extract alot more power from the consoles at that stage.
Most 1080p PS3 games were only 720p up untill just before TGS when dev kits were near their final specs, then the devs just had to program the game to run at 1080p.

 1080i vs 720p - Xbox 360 & Xbox Forums
I prefer 720p because that means that for every frame I see, I'm seeing 720 horizontal lines, not 540 (a la 1080i, remember the lines alternate, so you're not seeing them all at once).
A 720p progressive scan signal displays 720 horizontal lines in its entirety on-screen for 1/30th of a second.
720p is preferred when it comes to fast moving images such as sports.

 New 1080p tv - output 720p or 1080i? - TiVo Community & Store
And if a 1080p set simply reinterpolates 720p to 1080p, it will have the same freedom from motion artifacting (not to be confused with compression artifacting) for 720p content that any 768 or 720 set enjoys.
A native 720P signal fed to the SXRD is marginally better than allowing the HD Tivo to upconvert it to 1080i.
First, many of the games are made in 720p and not 1080i so you would be passing the native resolution to the TV if you use 720p.

The i stands for interlaced, as opposed to progressive scanning, used in the second HDTV standard, 720p.
Contrary to myth, 1080i is not superior to 720p; 1080i has more scanning lines but also suffers the disadvantages of interlaced scanning.
Contrary to myth, 720p is not inferior to 1080i; 720p has fewer lines but also has the advantages of progressive scanning and a constant vertical resolution of 720 lines, making it better able to handle motion.

 The New 720p Projectors
The least expensive of the 720p widescreen DLP projectors at the moment are the Mitsubishi HC3000, the BenQ PE7700, and the Sharp Z2000, all selling for under $3,000.
The fact that it is also the least expensive of the new 720p products, as well as one of the few to include a standard 3-year warranty, is a strange anomaly in the marketplace to be sure.
Hopefully this overview will clarify some of the salient differences between these extraordinary new 720p projectors, and help you to decide which of them might be the right one for your new home theater.

And 720p displays must convert incoming 1080i signals to 720p before they can be displayed.
If this is indeed the case, most people with 720p (or similar) projectors (and most DLP, LCD, and LCOS home theater projectors are exactly that) are not seeing what their displays are capable of.
Well, if you’re an owner of a 720p (or any similar resolution) projector you’re either gonna be really upset by this or you’re just gonna be laisez-faire about it because there’s nothing you can do and you’re enjoying your projector just fine thank-you.

Prior to that almost nothing accepted 720p, with the main exception being the HD plasmas that ran at 720p natively.
The ONLY way for this to be true is that Halo/XBOX 360 *really* outputting 60fps, 720p at 60hz, AND your TV accepts this and displays 60fps at 60hz (there's a different frame every 1/60th of a second).

People (such as Congressmen) read "our" 720P proposal and "their" 1080I proposal and assume that 1080I is superior because the number is larger.
Not only is 720P superior to 540I in quality (note the well-known artifact: interlace flickers), but it is cheaper!
The "high definition" formats, 540I (aka 1080I) and 720P, have to be compressed by about 50:1 to fit them in the alloted digital channel.

The ONLY reference to 720p in the manual is where it states that a 720p signal needs to be converted by the DTV receiver to one of the three aforementioned compatible signal types.
One important factor is that at the time all this was being discussed (over ten years ago), nobody really had a clear idea of what the picture would look like or even what display devices would be popular at the time it started to be widely adopted.
I guess my biggest complaint it that the TV was sold as being 720p capable in addition to the 480p, 480i and 1080i.

 To 720p or not 720p? HDBlog raises the question. - Engadget
According to some experts, 720p displays typically pick up just one 540-line field from each two-field 1080i frame, discarding the rest of the data, rather than sampling it.
AFAIK, all of the displays they had showing ESPN were 720p displays, so there shouldn't have been a real difference in aliasing unless some of them were discarding lines rather than doing true downsampling.
There's no reason why a 720p TV couldn't de-interlace the signal and then downconvert from there, giving you a true 1280x720 on every frame (although it would be 30fps...

The magazine says that "At the time of going to print, Wii games will output in 720i and 720p." Of course this is the same magazine that (incorrectly) said that the Wii's base was its power brick.
It was a simple typo, clearly it was meant to say 480i and 480p, as should be clear by the fact it goes on about your TV's standard resolution.
For instance, the game ran at 720p but wasn't as visually outstanding, but at least backgrounds and menus were high def.

I should note that split screen in 720p has obvious benefits.
