Yes, I have - and probably will do so again out of sheer insistence
that this problem is just too nutty to have happened legitimately.

Like I said, I've positioned the desktop so that there are six columns
of non-lit pixels on each side (so the image is centred at least - it
wasn't at first).  I've also confirmed that the TV rez is at 1360x768.
 I guess I'll make sure that there isn't a horizontal or vertical
stretch somewhere.

I just can't get away from the fact that the screen was fully used
while I was using my nVidia card, and that this happened after I
pulled it out in favour of my on-board intel.
