I've seen conflicting reports on this online, with some people saying that this is only their name for some kind of technology to simulate 120hz, and some people saying it's the real deal. What is it? I noticed that I can set my graphics card to output at 24hz if I'm displaying on the TV, does that mean it is 120hz, or does it not mean anything? (I know I can't do that if I'm just displaying on my regular monitor which I know is 60hz.)
