motion flow in useless in video games - it causes a lag in the picture of one frame.
A 30hz game will have a 1/30th of a second delay when motion flow is used.
It is only good for in movies since they dont require real time visual feedback.
The only way to get motion flow in games is simply to make the games run at 50 or 60hz from the box.
I can easy spot difference between 30 and 60 Hz but 60 and 120 hz not so sure.
120 to 240hz is probably not going to be even noticable it's puerly prestige factor.
As for contrast ratio anything over 2000:1 is pretty much pointless - digital TV images use 24(8bit RGB) bit color the extra contrast is pretty much useless unless color is 48(16bit rgb) bit and then it exceeds what is perceptable anyway. You are better off considering the maximum brightness since that produces a far more appealing and lively image.
