[mythtv-users] overscan setting

[Will Constable]

Thanks for the input-- im going to try the nvidia-settings route.  It seemed
like I didn't get any results at all when I changed the decimal value for
overscan in xorg.conf and restarted x... hopefully I'll have more luck with
nvidia-settings.

In any of the nVidia drivers newer than six months old
(and maybe older than that), you can adjust the TV
overscan in the nvidia-settings program, and it does
not require a restart of the X server.

In fact, when I was using an S-Video connection to my
TV, I had stopped placing the "TVOverscan" directive
in xorg.conf long ago.
