Just recently I started using Pete's OGL2 renderer in ePSXe v1.7, and I have a question somebody here might be able to answer.

Concerning the "Stretching Mode" in the OGL2 renderer. Which of the modes is the most accurate insofar as looking the same way on the monitor as it would on a television screen? Without distorting the graphics to fit the monitor (squashing them in weird ways)?

0 stretch to full window size
1 scale to window size keep aspect ratio
2 keep aspect ratio stretch on small heights
3 try to keep pixel ratio

A lot of PS1 games have strange resolutions natively, so if my fullscreen is running at 1024x768 for example, using option 1 would stretch the resolution of the game's image in some way to make it fit the monitor's resolution right?

But when I use "pixel ratio", I get small black borders around the game's image on screen. Which makes me think that the game's image is now properly sized to an accurate multiple of its true resolution (hence the black empty space around the image on screen) instead of being stretched unnaturally until it fills the screen.

So that is why I am wondering about all the stretching options, and which one is truly accurate (for a 4:3 monitor indeed, but what about widescreen monitors then)?
