I am also advised that if a mirror did stop working it wouldn't be out of
action 100% of the time and it would supply the colour range that would
apply to the appropriate *on or off* state of the affected mirror.


Sorry, that isn't very well-worded - it is the screen pixel that wouldn't be
out of action 100% of the time due to the 'stuck mirror'!

(Not sure that's any better wording...??)
