I've been running GCII et al in 1680 x 1050 for a while, but movies and certain static menu elements tend to get stretched out. I wanted to bump it down to 1400 x 1050, which is a 4:3 resolution and runs centered on my monitor with black bars on the side (in other games, that is).
1400 x 1050 isn't on the default resolution list, for some reason. And when I set the Custom Resolution option in-game and then change the resolution in prefs.ini to 1400 x 1050, the game hangs on startup. All the other resolutions (1024x760, 1280x960, 1440x900, etc.) work, but 1400 x 1050 doesn't. It's just the 4:3 version of 1680 x 1050, so I'm not sure why.
Anyone know what the problem might be?
