There is definitely an overscan setting (at least with 256.35.). It
may only appear if you run nvidia-settings on the TV? (I've never
hooked up a monitor to mine, strictly TV.) If your menu is off the
edge of the screen on the TV, find out what the keyboard shortcut is
to activate it -- perhaps Ctrl-Esc?

Anyway, there's a slider for "Overscan Compensation" under "GPU 0 -
(GeForce 8400 GS)" -> "TV-0 - (TV-0)". I found '50' to be a good
setting -- be aware the overscan will be different when displaying
lots of white vs when displaying lots of black, so it will never be
perfect unless you only display featureless gray images. ;)

After you get this set, you'll need to go into "nvidia-settings
Configuration" on the bottom of the left pane and "Save Current
Configuration" which will put am nvidia-settings-rc file in your home
directory; you will subsequently need to load this file on X startup
with an "nvidia-settings -l" command in your .xinitrc file prior to
your window manager being loaded.
