I don't manufacture the headmount display.  It takes a single composite
input and frame deinterlaces it, displaying half of the frames on one
display, and half on the other.  So that's the input spec I am left to
deal with.

As far as concerns with the display "knowing" which eye to start
displaying on, it doesn't.  You can simply toggle between "left first" and
"right first", if that makes sense.
