I am assuming that the line appears only with a raster on the
screen (i.e. powered on) and is not visible when the monitor
is off. Then, when you say the line is "one pixel (wide)", does
that mean that the edge of the line is sharply defined, or does
it have some shadowing around the edge? A comment, later
(Eben?) thought it was due to a stabilizing wire. This would
imply that the line is mechanically produced and is some sort of
shadowing artifact. If so it would have an edge that may not
align exactly to the phosphor dots. If it is electronically
produced, then I would think the edge of the line would
align closely with the phosphor dots (assuming the scan lines
are correct).
This is an interesting forensic type question. You might
want to use a jeweler's loupe to study the exact nature
of the line. So far it seems it could be due to either cause.
You could try one of those diag programs that make the
screen show solid colors and see if the appearance of the
line is color-dependent.
I'd love to hear whatever you discover.
