In short - no.

The reason this happens is that TVs have "overscan" which is about 2%.

If you've ever run a VGA signal into a composite adapter then to a TV you
notice that the sides are not vertical... instead they buldge in and out
depending on how much dark and bright is in that line.  Even expensive
tube TVs do it.  So the answer is overscan.

Try googling for "nvidia overscan" now you know the name ?
