Windows 7 docking station dual monitor display - does not save settings

original title; Windows 7 docking station dual monitor display

I have a laptop that is currently on a docking station with extended dual display setup.  There is a 22 inch monitor and the laptop as the secondary display.  When I undock it, it reverts back to single which is great.  But when I dock it back on it will revert to duplicate display mode and not save the extended mode.  I have to manually change the settings to extended every time.  I have read that Windows 7 defaults laptop screen settings to duplicate and desktops screen settings to extend.  Is there a way i can change the default laptop setting to extend.  Thank you.
