I wouldn't even notice if I didn't compare it side-by-side with my

Consider trying one of the Noscale mode lines described here:

Anyone able to tell me what I'm looking for?

have you tried changing your DisplaySize parameter under the Monitor
section of /etc/X11/xorg.conf? (on FC).

fine tuning this paramater and working with the nvidia overscan
setting fixed similar problem for me.

You say this is an EPIA, are you using the Unichrome driver?

If so, only the modelines built into the driver will work, and you must
match those names.

It sounds like you are not using a modeline that has overscan. The
driver should have a mode "720x480" with no overscan, which is what it
sounds like you are using, and "720x480Over" that has "normal"
overscan. If you are using a newer version of the driver, it will also
have "720x480Noscale", which I use, that has only a little overscan,
and turns the scaler off. There are also "640x480" and "640x480Over"

If you have the Unichrome source, the list of mode names are in
via_vt162x.h.

Hope that helps.

You need to enable overscan on your tv out. There's lots of useful
information on setting up tv out on an epia here:
