LCD Refresh rate

[jeevez]

I've seen in several places how a "refresh rate" on an LCD is sort of a made up number and that response time is what matters because of the way LCD's handle changing the image. I have a friend who is dead set on not believeing the advantages of a higher refresh rate LCD because of this. I've tried to explain to him how it's important for things like Blu-rays because gets rid of the 3:2 pulldown. Unfortunately neither I nor him have a 120Hz TV to demo this sort of thing and have nowhere near the resources to be getting one (both in University, only one more year!!). I was wondering if anyone could give me a straight forward explanation on why this 120 Hz actually matters. If we were to go somewhere that had a demo setu pwith a 120Hz display playing a Blu-ray, would the difference be noticeable? I've looked at the "120Hz explained" thread a few times, but it's not really the answer I'm looking for. If anyone can give me a hand in coming up with a way to explain this to my strong-headed friend, I'd really appreciate it.

Thanks!
