Tested current status (humanity-icon-theme 0.4.1-0ubuntu1, gnome-settings-daemon 2.28.0-0ubuntu2).
$ dpkg -S gsd-xrandr.svg humanity-icon-theme: /usr/share/icons/Humanity/apps/24/gsd-xrandr.svg gnome-settings-daemon: /usr/share/icons/hicolor/scalable/apps/gsd-xrandr.svg humanity-icon-theme: /usr/share/icons/Humanity/apps/48/gsd-xrandr.svg
The ones in humanity-icon-theme are currently symlinks to display-capplet.svg. Changing them confirms comment #8: gsd-xrandr.svg is only used in the tray, and the system menu won't be affected. Thus, a new icon seems to be all that is needed.
