You can't, there's no command line interface for xfce4-display-settings
(only '-m' to start the minimal dialog). The --display option you're
trying to use comes from gtk, and doesn't have the same meaning as
xrandr displays (:0.0 vs. LVDS).

You should use xfconf-query instead to set directly the xfconf
properties (e.g. "/Default/LVDS1/Resolution" to "1280x800"), and when
you're done, set "/Schemes/Apply" to "Default" to let xfsettingsd apply
your changes.
