This channel configuration doesn't seem to make sense. If the offsets of the
left and right channels are +90, and -90 in pitch, then one monitor should be
facing foward, one is to the left 72 degrees, facing down, and one to the right
72 degrees facing up. Why would you want your monitors in this configuration? I
don't think the horizontal FOV should be continuous in this situation.
