If you hook up your Xbox, it will always be 480p with the possibility of 720p. 720p is your choice.

BTW Don't you have to "activate" 480p on GCN games using some sort of hotkey?

Just once the first time you use progressive.

Lots of Gamecube games are 480i only, and to the best of my knowledge none display at anything above 480p at all. Nearly all Xbox games are at least 480p, even if it supports higher. Hook up your XBox to your good tv and enjoy the high rez games that both systems have to offer.

At least the new MX Unleashed game is 1080i on the Xbox so I do have something to eyeball. I just wish all the Xbox 720p games were 1080i.

This thread makes me dizzy,

I dub this thread, the Official Nerd Thread! Congratulations.

Does posting in the Official Nerd Thread make one a nerd? I think so. :)

Explain to me the word D1, D2 and D4
What does that mean?I just a TV with D4 in Japan.Maybe that's 1080i

Within the 18 ATSC formats that comprise the HDTV format in the US, there is no such thing as 540p.

The confusion here stems from the fact that timings for a 540p signal and a 1080i signal are similar. An HDTV display that can display a 1080i signal is also able to display a 540p signal, however, that is technically not a supported HD format.

Some owners with a 1080i display that can't display a 720p image, yet want to display a progressive signal use 540p timings. That's what the page that edstein linked is describing.

As for whether 720p or 1080i is better, it depends on who you ask. Personally, I'd choose 720p over 1080i and I would never buy a HD display that could not display 720p natively. I thought it was a stupid move for the ATSC to include any interlaced formats in the HDTV spec at all.

In any event, the reason why most XBox games support 720p instead of 1080i is probably mainly because the frame rate would slow down too much at 1080i. My guess is that architecturally, the XBox can't render an interlaced frame. It can only render progressive frames and therefore to output a 1080i signal it's actually got to render 1080p video. That's 1920x1080 resolution at 60 fps, which is probably more than the XBox can handle with most games.

Finally, Kumar, I'm not sure what D4 would mean in relation to your TV. Usually, D1, D2, D3, and D5 refer to broadcast quality digital tape formats. They are all standard definition formats, though, and there is actually no D4 format. So I guess what I'm saying is that I have absolutely no idea what a TV that refers to "D4" could possibly mean.

540p is a common format in home theater pc (HDPC) circles. It allows you play DVD's at a higher resolution than 480i/p which normal DVD players use. Check out the www.avsforum.com for all the details for setting up such a system.

Thank you! I've been trying to get this to work correctly for days, since my projector only accepts progressive in the VGA (component) input. Not sure why I even had 1080i turned on in the xbox.

Also, all Toshiba progressive scan displays upscale 480i and 480p signals to 540p in order to keep the same scan rate as the 1080i circuitry in the TV.

So, 540p does exist, but as has been said here a few times, 540p and 1080i are not the same. If they were the same, you'd have to say that 240p = 480i. Not the case at all.

Just to muddy the waters even more, my mitsubishi has a 960i mode as well. This would be the equivalent timing as 480p.

lol, that makes no sense, I wasn't the one discussing 2160i and whatnot.

Yeah, like mine. The point is that 540p is not a valid "HDTV" resolution. There isn't any HD content in 540p. It's 720p or 1080i. There are plenty of other options within the established scanrates, but none of them are HDTV standards.

Don't the newer toshibas support 720p native, though? They probably still upconvert 480 to 540, though.

There are only 3 HD formats: 720p, 1080i, and 1080p. Anything else is not high-definition.

However, there seems to be confusion in this thread about what the 18 ATSC standards are. They aren't all HDTV. Only the above 3 are. The rest are all digital broadcast standards that can be significantly lower than high-definition.

Why make a game in 720p? Sit back and let me tell you why. Have you every played Soul Calibur in 720p? OMFG...if you haven't be prepared to pee in your pants. The picture is so clear and crisp it makes some of my PC games cry like a baby. Not to mention in 60FPS with no drop in framerates. Nothing beats looking at those jiggles ....er I mean sword fighting at such a high resolution... OH the beauty of it! ;p

So if my set does 480p or 1080i, what should my X-Box settings be at?
480p on or off
720 on or off
1080i on or off

Beau

I saw this model in Tokyo and it had 4 D4 inputs.So I think it's 1080i.D4 in Japan means 1080i ,so the image should be very good

Here is the Panasonic Japan link

I would go with:

480p on
720p off
1080i on

If your set converts 720p to 1080i, turn 720p on too.
