System sends a WM_DISPLAYCHANGE message to all windows when the display 
changes. see:

 http://msdn2.microsoft.com/en-us/library/ms534847.aspx

Just intercept this message by defining your own wndproc for the main form 
and looking for this message.  Then you should be able to be informed when 
the screen settings change
