As I recall, and it has been awhile, it was not obvious where the overscan
was in nvidia settings.  I can't run it so I won't be much help.  I guess
you can run  nvidia-settings -a TVOverScan[TV-0]=20 from the control line to
be sure but what you have done should work I would think. I would still try
it just to be sure.  I was going to try it on my remote FE but it doesn't
have a TV.  I am afraid to run it on my main FE because of some specific
conflict I have with my air2pc card.  There certainly is no overscan setting
in my remote FE and I certainly have no overscan in my main FE so it must be
working.  If you are sure it is not there in your system, I can play around
more on mine to see if it will help you.
