Why is this no longer true?

[Jun Mukai, 2013/05/16 00:04:15]

This was true because display-options is the settings page for multiple display
arrangements (top/left/bottom/right, mirroring/non-mirroring, or something like
that)

This is not true because the new display-options also includes single display
settings like screen resolution change and screen rotation.
