Because when two displays are connect (internal display and HDMI
projector) it is normal to see mirroring options in the Display System
Preferences. Either that, or "Arrange". You say these options are not
there, which I find very strange.

That could be (I have no idea if HDMI supports any data back, but I'll
take your word for it), and it would certainly be another reason for the
HDMI to never show an answer button.
