Screen Metrics settings for the auto-resize window feature?

[utaeladil]

I set this up a while back, and I know I was reading instructions from somewhere that told exactly what "screen metrics" settings to use for multiple monitors... well this holiday I got a new monitor, and I moved it to the other side of my smaller one... but now I cannot for the life of me find the screen metrics settings instructions anywhere to just set it so it loads windowed-full screen on my OTHER monitor... When I try what I THINK it should be, its placing the entire game off-screen on startup and I have to do a few sneaky things with the resolution and alt-enter to get it back visible so I can work with it...

I just need game in 1920x1024 on my left monitor now instead of my right one. Or a link to the directions so I can change it anytime I need to.

Thanks!
