Open your config.ini which is in the root IL2 folder with notepad and look for the header[Windows],change width to 1680 and height to 1050
making sure also that enableResize=0 and SaveAspect=0

[window]
width=1280
height=960
ColourBits=32
DepthBits=24
StencilBits=8
ChangeScreenRes=1
FullScreen=1
DrawIfNotFocused=0
EnableResize=0
EnableClose=1
SaveAspect=0
Use3Renders=0

that should do it I think if I remember correctly
