60 vs 120 hz refresh on new samsung 55 led tv 120hz

I just bought a new 55" LED Tv 120hz and notice it says when I change channels the hertz is only 60hz.

I am connected to a cable box provided by Cox Communications. Is it a setting in my TV that's wrong or is it the box provided by Cox?

Thanks,
Roy
