I have read that difference between 1080p and 1080i is noticeable on screens 50 inches and above.
So, it is ok to have 1080i on 40-incher and below.
The discs are encoded at 1080p. Accdg to many early adopters in an AV forum I frequent, the Tosh A1 output at 1080i and with 1080p-capable HDTV upsampling to 1080p regardless of input, the resulting video is indistinguisable between 1080i and 1080p input, regardless of screen size. And they were talking about it over 100" PJ screens. All fixed-pixel display technologies (plasma, DLP, LCD, LCoS, etc.) are naturally progressive and require deinterlacing of interlaced input. And because with a 1080p source like HD DVD and BR discs, ALL the video data is completely transmitted and the players simply output them sequentially at 1080i, rather than all at the same time at 1080p per unit of time. Since the data is buffered and reassembled(de-interlaced) and displayed progressively in the monitor as 1080p, the resulting video is no less gorgeous than if the display accepted a 1080p input. No motion artifacting common with interlaced sources. So for practical High Def HT experience, the current toss-up between 1080i and 1080p input capability in displays is irrelevant when talking about 1080p-encoded sources. Some would even say that 1080p is a waste. But I don't think it is. To the extent that the display may not be de-interlacing properly, which may happen with cheap HDTVs, 1080p input has its value. But I have to admit all the hype about 1080p has convinced the market that it is superior, and no amount technical punditry will convince them that for practical HT high def, they have the same pixel count and can't be distiguished.
I had commented on another sting a few weeks back that I viewed the Pioneer 1080P next to the 1080i and could not tell any difference. Now I see why, there really wasn’t any difference! Except for the $6,000 premium the 1080p had on it.http://www.soundandvisionmag.com/idealbb/view.asp?topicID=52175&pageNo=1&num=Now, how can XBOX 360 implement 1080p on games if it doensn't have HDMI out?
I am not so sure if the HD-DVD add on has HDMI.
If there is, the 1080p for movies is ok.
I haven't come accrossed yet of HDTVs that accept 1080p through VGA.
From what I know, VGA is analog signal. I may be wrong though.
VGA is analog and yes, most HDTVs don't have support for 1080p via VGA but only a few. But like I said, with the vast majority of HDTVs now in homes having no 1080p input capability, MS had been saying all along that they will upgrade their xbox WHEN the market has the gears to accept 1080p, not before. MS may be simply pragmatic to say that its market don't use HDMI yet, and rightly or wrongly designed the xbox without HDMI support as HDMI was still nascent at the time it came out of the drawing board. But I must say they should have included it with their add-on, if only to match what the PS3 has. This is admittedly a drawback for the xbox as far as printed tech specs is concerned, but not in practical terms. Why? How many HDTVs accept 1080p? Virtually zilch, whether via VGA or HDMI. 1080i is the threshhold for HD. The ITU-R standards specifies it as minimum. And true eniough, 1080i input via component is said to be glorious enough since all the data wll be upscaled to 1080p by any competent HDTV - not something you'd lose sleep over.
