Yeah yeah, we get it. I'm wrong... oh I'm soo wrooong....aii yaaaaiiii!!
"You CANNOT play back a 24p movie on a 60hz set without judder, the frame rate doesn't divide evenly."
Since you're SO right, and ^^that has got to be absolutely true, why don't I experience judder when playing 24p movies? It's a 60 Hz screen, and there is NO judder in slow or fast panning sequences, day or night scenes, indoors or outdoors, just to give you a fair idea.
What you are saying about the frames being divided when it comes to 120 Hz and 250 Hz sets is a fact, yes. But strictly talking about movies, a 60 Hz screen isn't inferior to a 250 Hz one, or even one that does 400 Hz or more.
Games come at 60 Hz, movies at less than that. However a 60 Hz LCD, if set up and tweaked right. will give you performance far better than a cinema screen.
Until and unless you have source content that runs at native 120/250 Hz, a screen higher than 60 Hz has no significant advantage, except maybe reduce the blur with fast moving images.
Fact: LCDs and LEDs will always exhibit a certain amount of blur, compared to Plasmas and CRTs.
Fact # 2: For 3D content, 120/250 Hz is quite useful
Fact # 3: If playing console games or watching DVD/Bluray movies is your primary use, anything above 60 Hz is not necessary. If you feel it is, then you're simply buying into the hype and marketing that's generated by motion enhancements.
Cheers then, enjoy your screen!
