You might have been - I haven't. All my earlier CRT sets were set up
correctly. I work in broadcasting production and watch underscanned
monitors. I hate seeing things chopped off when I know they weren't framed
like that.

The big difference is that early CRTs weren't rectangular so unless you
accepted a black border only the centres of each side, top and bottom
could be correct. Although some better makers like B&O actually masked to
a rectangle.

Modern Plasma, LCD and DLP etc all have near perfect rectangles. So there
is absolutely no excuse for any overscan at all. As I said before it's
done for the showroom to make the picture appear bigger - and probably to
save some effort in manufacture setting up.
