The problem is that there are not two cameras. The single viewpoint has to be sent though various projection matrices to come up with two screens.

That's fairly obvious, given panning and 3D (logic says you can't pan multiple viewpoints) - and you've pointed it out several times before.
However, if you provided 4 (optional) adjustments, then Morgan might be eternally busy playing with them, with the only complaint being that he could never get them adjusted
exactly right.
