Changing Dolphin's Fullscreen resolution

[tccalvin]

Hi there, I'm trying to get dolphin working at 480p on an old CRT monitor.

The only problem is that, while I can change the native rendering resolution of games, I cannot figure out how to make dolphin output a different resolution than the one that windows is currently using.

I've done some research and I've tried changing the Dolphin.ini file by inputting "Fullscreensize = 640x480", it doesn't do anything.

If windows is rendering at 720p, dolphin will scale whatever rendering resolution to 720p, no matter what number I have typed in the ini.

Help?

Thanks in advance.
