Maybe you could use something like this command (ofc with the values of
your hardware):

xrandr --output LVDS --off
xrandr --output VGA --primary --mode 1920x1080 --rate 60.0 --right-of LVDS

I don't know how to fire this up before KDM grabs the screen (I'm using
the startx command and ~/.xinitrc to bring KDE up after login into an
alpha screen).
