Spring RTS Engine

I have a monitor with the resolution 1920x1200 and another with resolution 1280x1024, how do I setup dual screen mode with this? the settings.exe only accepts 1 resolution and with different heights for both, stretching across the screen doesn't work (i get an error), any help?

we only have ghetto dual-screen mode right now...

you need an nvidia card, then enable horizontal span and set spring's resolution accordingly

I was going to make a lua'd minimap in another window, but I couldn't get lua sockets working...
