If you run xinit directly, it invokes the X server with no command-line 
arguments (assuming you're not setting any) and then sources your .xinitrc 
script.  startx is a "wrapper" script which invokes xinit with some 
additional command-line arguments.  Go ahead and look in 
/usr/X11R6/bin/startx to see what additional arguments it's passing to the X 
server.

Also, take a look at the man pages for xinit and startx.  They're pretty 
well documented.

You can customize the X server's behavior via command-line flags, documented 
here:

Use a Windows shortcut with a target of, e.g.:

c:\cygwin\usr\X11R6\bin\run.exe /usr/X11R6/bin/startx

I believe there is also a Cygwin package that installs Windows shortcuts 
that are intended for this purpose.  Don't recall the name, but it's in the 
same category as the X Server package.
