This depends on your display settings

If you have dual view:
[code:1]c:\Maximizer\Maximizer.exe --device 0 --margin 0,0,0,0
c:\Maximizer\Maximizer.exe --device 1 --margin 0,0,0,0[/code:1]
should work.

If you have horizontal span I have no idea, sry , but as you have 2 different resolutions i think you have dual view *g* so try the 2 lines above
