Its my understanding that most of the 1080p sets arent 'true' 1080p and they don't accept 1080p signals either, at least i know this is true of samsungs offerings
Yes and no....
There are only 2 products that can accept 1080p natively, the Faroudja DVP1080HD-DILA and the Sony Qualia 004 R2....
However, the Epson D4s, the R1 Sony Qualia, the Qualia 006, the JVC HD-DILAs, the 70-inch LG plasma, the 71-inch Sammy plasma, the 46-inch Sharp LCDs, ect....these are all TRUE 1080p displays...they will display every single pixel of a 1920 x 1080p Sencore or AccuPixel test pattern....have no fear....they *are* true 1080p...
The thing is that most of these products accept either 720p and upscale it to 1080p or they accept 1080i and de-interlace *it* to 1080p....
As you may or may not know, film is a progressive format and a 1080i film source (such as a D-Theater movie, for example) have progressive embedded flags which are *read* by the de-interlacer and is "reconstructed" to 1080p, if you get my drift......
So its like this:
1080p Film source--->1080i telcine process during video authoring--->Video player outputting 1080i video---->display converts film back to 1080p via inverse telcine process in de-interlacer----You viewing 1080p film that looks just like the 1080p master, in theory...
The big question is;can we detect any measurable or subjective improvement using a display that can accept a 1080p source directly over one that deinterlaces 1080i??
We will not have a fair answer to that question until we can compare the R1 and the R2 versions of the Sony Qualia 004s side by side....
That still won't happen for a couple more months, unfortunately...
So what does this all mean? Will the image of an xbox 2 game downscaled to normal 480i look worse than a normal 480i game?
Well....compared to what???
By all accounts, all Xbox 360 games will be 720p and the resize filter will do the rest of the
work if you do not have a 720p display.....so you will not see a 480 i/p Xbox 360 game to compare it to...
I would think that a 480i version of, say, SSX4 on the regular XBOX would still pale in comparison to the Xbox 360 version of SSX4, resized to 480i.....if that answers your question....
