The xorg documentation is applicable in case of a computer monitor that
you only watch from a couple of feet away.
In case of a TV that you watch from far away, the truth is not what you
want. The idea is to lie and tell X that the physical screen dimensions
are smaller than what they really are (because the TV appears much
smaller than if it was watched from up close).
