Yes, you are right, the black bars should be split equally between the
two views. The same bug also affected the top-bottom, top-bottom-half,
left-right, and left-right-half output modes. I have now fixed this (at
least it works for me):

I added a link to you original mailing list post to the manual. I did
not copy the xorg.conf sample directly into the manual because the
details probably differ between graphics card drivers and TV sets.

I'd rather avoid this; it is a system dependent mess. On X11, xrandr
should do this, and if it does not work for you, then there is no hope
that Bino would be able to work around this.
