120Hz @ 30fps / 60Hz @ 30fps

My guess is that a TV broadcast actually supports the refresh rate of your monitor.

Last time I asked about TV looking smoother than I've used to, I was told it had either 100Hz or 120Hz. Can't remember... But that gave me the idea of playing in 30fps with 120Hz screen and looking as smooth as 60fps.
But if it doesn't work that way, then I guess there's no point for me to buy 120Hz monitor.
