All PS2 games support 480i or 576i (depends on the region)
Some PS2 games support Progressive scan, therefore 480p and 576p.
Very few games (e.g. GT4) support higher resolutions, but the PS2 itself is capable of outputting up to 1080i.

Edit:The PS2 GPU internally uses 256x224 to 1280x1024.

So unless stated otherwise (menu option for progressive or widescreen) games are at least 480i and 576i? But none of this resolutions are 4:3 would that mean they're stretched into the screen?

Sorry you lost me here. What does that mean exactly?

It varies resolution from this range (256x224 to 1280x1024) and if larger than 1280x1024 is to be output, ie 1080i then there's filtering applied? Is that what I am to understand?

Also what putting frequency aside, what happens when different regions of the game are played due to the different AR? Is the image stretched or pan and scan is used? Which region calls for less distortion?

That's everything i need to know on this subject, if anyone could provide anserws to these questions i will comprehend to the best of my abilities how different region systems work.

If the internal resolution is different from the output resolution, I think the screen is stretched.
So, if you force a PAL game to output to NTSC, the internal resolution stays the same, so you are stretching the image.

Edit: If I remember correctly, if you force the output to something different from 480 or 576 the PS2 doesn't stretch, and since some games uses a higher resolution and relay on stretching to make the game look correct, you will get black borders and distorted output.

Well actually i sometimes use NTSC Games on a PAL console but i guess the same principles apply.

How is pan and scan distorted? You only view a different portion of the game but on its correct output. I thought that stretched AR is what's distorted?

What do you mean it's not 4:3. IT IS. 480i is 640x480 which is four times 160 and 3 times 160.

Wait, i think 480i and 756i means 720x480 and 720x576 which makes none of these resolution 4:3.

run a game in pcsx2 and use gsdx as GPU plugin, you can find the resolution right in gsdx's title bar.
So i tried the emulator and it displayed 640x448 for NTSC and 512x512 for PAL! Isn't that strange?

These are the settings i used.

No TVs support these resolutions, so the PS2 would stretch the output to a normal NTSC/PAL resolution

So for NTSC the 640x448 is stretched to 720x480 and PAL 512x512 is stretched into 720x576?

Wouldnt that create distortion due to unproportionate AR? Or are the textures re-drawn in a way that makes it look natural?I hope the latter is what happens.
