That's what footnotes are for.
Maybe:

So DVI-D feeding a LCD still has to deal with all those funky blanking
times, front and back porches, and such?
Yeah. In fact, I think the way DVI protocol works, you can't actually
be sending active pixels and change a sync signal at the same time. I
could be wrong, but I think those things are sorta meta-encoded into
the pixel stream. The result is that you're FORCED to have at least
some blanking. Also, most monitors expect certain minimum blanking
times, and I know that in at least a few products Howard and I have
worked on in the past, we've COUNTED on having that blanking time for
various reasons, no doubt something that monitor manufacturers often
do as well. Furthermore, the OGP video controller counts on having
blanking time like that so that FETCH, and INC instructions can be
inserted (plus, the sync has to have porches in order to be a
"pulse"). We too force you to have at least 12 pixels of blanking (6
in single-link DVI mode) per scanline.
These things don't mean what they used to, but since they're there,
designers take advantage of them.

Too late. :-)
I was talking about the people at the show. :)
