Which brings up the question: exactly how is a line of resolution defined?
Consider an alternating pattern of 640 white and dark lines (320 white,
320 dark) that my computer is displaying on a TV set.  I look closely and
can see all of the white and dark lines (they don't merge).

Am I seeing 640 lines of resolution, or only 320?  By the above description
(since it says 500 lines vertical, and there are only 525 scan lines to
begin with), I'd assume I'm seeing 640, but inquiring minds want to know.
