I don't see the benefit and point of getting the hertz down that low. I'm happy with mine at 60Hz, don't see a need to change it. Though, mine can't go into the 20s, I'm fine with it at 60 or 59.5. I would think that in 3 months of "research" that you would find something or a forum somewhere that would tell you it. The settings in nTune can adjust the monitor just as well as Rivatuner, no need to get that when nTune works to what he needs.
