Help with PS2 to PS3 Upscaling

[ChadVader]

I'm running a 60gb PS3 over HDMI at 1080p. It plays ps3 games in 1080p fine. When I put in a PS2 it upscales it fine, but only when it's at 480i. However when I change the game to 480p the screen display changes to 640x480, which means of course it is no longer upscaling.

It seems that my only options are to have 480i upscaled to 1080i or play at 480p. Where's my 480p upscaled to 1080p? Am I missing something? Thanks.

Where are you changing your settings. Are you "in-game" with your PS2 game, pressing the PS button and changing settings from there?

Something sounds weird here, because I run all of my 480i PS2 games at 1080p. Recheck your settings.

I think he's swapping the in-game setting to be progressive scan. I know games like God of War and Tekken 4/5 can do that.
When you change the settings in-game, it'll change the resolution to that one.
What you want to do is change the in-game stuff to 480i, save your game and then restart it. It'll upscale the 480i to 1080p.

Yes the games are playing at 480i upscaled to 1080p. But if the game is 480i then 1080p is basically running at 1080i, since it's only running 30 fps (or 60 half frames per second).

My question is, why is it impossible to run 480p upscaled to 1080p? You would get the best of both worlds...

So, yeah, I see what you're trying to say, but it's not true. The key point you're missing is that the PS2's 480p mode is running at 30fps, not 60fps. 480i60 + deinterlace = 480p30

It's such a corner case that Sony didn't bother to add support for it, is my guess. Also, as I pointed out above, who cares if the game or the PS3 does the deinterlacing? There's still that huge 480p -> 1080p step involved.

Ok, this makes a lot of sense then. So basically PS2 has never been able to display 60 full frames per second.

I know this is slightly off topic, but what about the Wii? Is 480p just 480i deinterlaced? Right now I'm running it through S-Video into my TV-Card, and then using DScaler to deinterlace it for me. If I buy component cables I'll also have to buy some sort of VGA box = $$$.

Thanks.

Well, give or take. Let's not get into the discussion of internal rendering versus video output.

That is exactly the case. IMHO, DScaler is quite excellent and produces little lag (if you're careful about configuration), so I wouldn't bother with the VGA box.

There is such a thing as 480p60, but it is somewhat unusual to find devices which output it.
