Probably better:  "xrandr --output HDMI-0 --mode NNNxMMM --same-as 
DVI-0" where NNNxMMM is the native resolution of your DVI-0.  Assuming 
that the TV has more pixels than your primary monitor here--if not, then 
you'll probably have to do something like "--scale-from NNNxMMM" instead 
of --mode.

That should be "--set underscan on".  Sigh,
