You can edit your config.ini file to accommodate other screen resolutions than those available in the game setup itself. The config.ini file is in your game root directory.

If this is the first time you're changing something in this file, please MAKE A BACKUP COPY FIRST, so if something untowards happens, you can simply use the original file again. It's quite simple to change, but you never know. Better safe than sorry and all that ...

Anyway, you need to adjust the following settings in the config.ini

width=your screen width in pixels
height=your screen height in pixels

Here is my setting for a 1440x900 pixel widescreen
Also set 'saveaspect' to '0'

[window]
width=1440
height=900
ColourBits=32
DepthBits=24
StencilBits=8
ChangeScreenRes=1
FullScreen=1
DrawIfNotFocused=0
EnableResize=0
EnableClose=1
SaveAspect=0
