It's 1920x540. You interlace over lines, not columns. And that's what sometimes is called "native" 1080i. Some games just render in 720p (1280x720) and upscale to 1080i. |
Actually - (and I already know about 540p) the trick that is used on the PS3 to upscale the games to 1080i is to render the image in 960x1080 first, which can then be upscaled to 1080i/p easier than 1280x720 could.
There were a few articles about this several months ago (around the time the "secret scaler chip" was being talked about). Several games use this trick (Ninja Gaiden Sigma being one of them - if you look up close to the "1080p" NGS image on a 1080p display, you will see it is not 1:1, but has been stretched horizontally)
-and there isn't an actual dedicated scaler chip - the 'scaler' is the RSX.
