[quote name='oasisboy']Can someone explain the difference between double scale, normal and full screen?
For the ps2/psx, what games would use the normal setting and which ones would use the full screen setting?? I need more info on this...[/quote]
DVD
Normal upscaling upscales the picture to the highest resolution and matches your screen size.
Double Scale works slightly differently, but basically it windows (puts black bars around the the entire picture).
I'm guessing you only use Double Scale when a DVD has bad underscan problems. I use Normal because it works better on most DVDs I've tried, and I see more of the picture around the edges than ever before.
Use Normal.
PSX/PS2
EVERY PSX game is 4:3, your regular square box ratio, so always use Normal.
Most PS2 games are 4:3, but some of these games have an option for 16:9 in the game menu. Just play the game, and check. Sometimes it says on the back of the box as well.
There's also a website that lists every widescreen capable PS2 game.

On those widescreen games, use Full Screen upscaling, so that it'll properly stretch the picture. Make sure you change the setting in the game as well.
