Once upon a time, in the days of analog displays, we used modelines to 
accomplish what you're doing.

I don't think modelines work with pure-digital outputs, though. Does your TV 
have a VGA input, and does your box have a VGA output? That would be an 
effective, if not ideal, solution.

Alternately, have you tried setting your display to an unusual resolution? 
What's the output of the xrandr command? It should give you a list of 
supported resolutions refresh rates, including flags to tell you which ones are 
selected and which ones are recommended. Often, with digital TVs, there will 
be a resolution you can use that evades the TV's overscan emulation.
