Should I be suing 720p or 1080i?

I'm not the best person to ask for this, so someone else should probably clarify this if I'm mistaken, but I believe most PS3 games only support 720p in the first place. There are exceptions, like Metal Gear Solid 3, but even in that case, you'd probably be best served just keeping with 720p.

Are you using a CRT?  Then 1080i, are you not using a CRT?  Then 720p.

" I WILL SEE YOU IN COURT, 1080i!!!!! "

" My HDTV supports both, my Resolution is 1366 x 768. not sure if itll be better to have 720p and 1080i Checked off on my PS3, or just keep it only 720p.   EDIT: cant edit title, sorry for incorrect spelling "

I've switched back and fourth from 1080i and 720p a million times on games that support both resolutions, the only difference I have ever noticed is that text looks a lot sharper and crisp on 1080i. I can't tell any other difference. 720p is supposed to look better "in motion" because of progressive scan but I can't tell, it looks the same to me.

You can check both and your PS3 will decide based on the game you're playing.

1080p, if you cant then buy a new TV.

"1080i is actually only 540p,"

My tech expert friends tell me to use 720p over 1080i.  I have no reason to doubt them, so that is exactly what I use on my Panasonic plasma.

720p, because.

720p because off the p

Umm...no.  1080i=1080p in terms of resolution...the only difference being that every other line of the image is refreshed every 1/60th of a second, while with 1080p every line is refreshed every 1/30th of a second. As for seeing differences with tvs 40 inches below, it depends how far you sit away from the screen. The smaller it is, the closer you need to be to see. "

In 1080p, each frame of video is sent or displayed progressively. This means that both the odd and even fields (all 1,080 pixel rows or pixel lines) that make up the full frame are displayed together. This results in a smoother looking image, with less motion artifacts and jagged edges."

1080i is rendering 1920x540 at 60Hz or 1920x1080 at 30Hz.  Basically if a game, TV show, or movie is rendering and outputting 1080i at 30Hz and your TV can display a 1080i image, you're seeing exactly what a 1080p signal would show (the game would support 1080p in that case anyways).
 
Anyone who says 720p is flat out better doesn't understand the tech.  On a HD CRT, 1080i is better than 720p, fact.  A LCD or plasma that only supports 720p would have to scale a 1080i image, which would negate the point of rendering higher res in the first place.

If you cant use 1080p then u r best sticking with 720p or test bith out urself and see which one u like best

You sound technical, but you still don't know what you're talking about. 
The difference between 1080i & p is the way it displays the lines of resolution, it isn't the same at all. 
The only difference that matters is the interlacing of the lines, 1080p shows them all @ once & 1080i flashes back & forth.
Technically 720p is better & will look smoother then 1080i.

" In 1080i each frame of video is sent or displayed in alternative fields. The fields in 1080i are composed of 540 rows of pixels or lines of pixels running from the top to the bottom of the screen, with the odd fields displayed first and the even fields displayed second. Together, both fields create a full frame, made up of all 1,080 pixel rows or lines, every 30th of a second.

In 1080p, each frame of video is sent or displayed progressively. This means that both the odd and even fields (all 1,080 pixel rows or pixel lines) that make up the full frame are displayed together. This results in a smoother looking image, with less motion artifacts and jagged edges."

Most people don't have the proper settings to view a picture at a 1080 resolution so you might as well as have 720p.

well shit, this case could go on for years. i hope you have a good lawyer. 

" Are you using a CRT?  Then 1080i, are you not using a CRT?  Then 720p. "

Not to hijack the thread... but now I'm suddenly confused wither I should change my Wii to display 480p opposed to 576i. I have a full HD LCD TV. 
It sucks when techno-babble starts to be confusing instead of helpful :-/

i would say play it at 720p. it is not better and with 1080i u see a lot more lines then 720p.

Your choice I guess.  I have my PS3 set to 1080i.
