    There was. They've pulled it.

    Should have bought the box earlier. :p

    Hi, first post. I gotta say the sheer amount of info here is amazing, keep it up. Now my question. I have been reading that Uncharted's native resolution is 960x1080p, how is that possible?

    Btw, scaling sucks.

    It's not
    the 960x1080 rendering mode is a special mode that they have devised for TV sets that support 1080i but not 720p. (generally old CRTs)

    other than that it usually renders in 720p as usual.

    The way they do it is that they render it at that resolution and then apply a horizontal 1:2 scaler to it. giving the result a 1920*1080 resolution.

    960x1080 is generally better than 1280x720 for 1080p TFT/plasma screens also -- it gives you higher quality scaling in general than scaling from 1280x720 to 1920x1080.

    Nah, the PS3's 960x1080 to 1080p scaling is weak. Any decent display will do look upscaling 720p on it's own, even though it is a lower rendering resolution.

    depends, all you need is a 1:2 horizontal scaler, how weak can it be? you turn 1 pixel into two pixels, I'm not exactly sure how much scaling ability is needed for that.

    Hello guys. Uncharted is 960*1080 so ...

    Have Uncharted Drake's Fortune AA ? 2x or 4x ??

    You will find the answer in this thread already.

    Drake is natively 720p, 960*1080 is just for 1080i mode only and is upscaled horizontally..

    PS3 WWE screenshots are interesting, i see the harry potter artifact except that edges have 1280x720 aspect (not 2560x720p aspect like harry potter), i think it's 640x720 native resolution with 2x MSAA (1280x720p no AA on X360) and mix the two MSAA buffer in one 1280x720p framebuffer

    if a game use 640x360 with 4x MSAA and merge the four MSAA buffer in one 1280x720 buffer then it will be difficulte to prove the native resolution (because in this case there are no visible artifact on edges)

    Re: Uncharted 1080p support, I've read that if you de-select 1080i and 720p, and select 1080p from the PS3 display properties, Uncharted will output the signal as 1080p. I have no idea if it acually looks better than 720p upscalled though... IIRC CoD4 is the same...

    It use simple bilinear extrapolation, where as any decent TV's scaler uses better algorithms

    I know MP3 is 640x448. I think most would be around that or 480.

    I don't know if any games actually use an isomorphic widescreen resolution.

    It's better to interpolate 2x bilinear on one axis then 1,5 whatever and 1,5 whatever on both :)

    Only if your goal is less scaling rather than better image quality.

    2x scaling is way better then 1,5x ;)

    It definately is not. 720p upscaled to 1080p looks significantly better than 960x1080.

    Yeah, I think it's a matter of aspect ratio. Since you have so much more screen to fill horizontally you don't want to give up horizontal resolution in favor of vertical resolution.

    That depends of the AA level, with AA it's very hard to notice any difference.
