Quote:Examples of motion blur:
go to www.testufo.com .... More motion blur at 30fps than 60fps (on LCD)

Going to 120Hz typically halves motion blur. However, if you are able to enable a strobe backlight at one strobe per refresh, on fully refreshed LCD (between the LCD refreshes), you've got a strobed sequence of very sharp frames, and much shorter persistence, so you get less tracking motion blur. Look at the LightBoost testimonials as an example.
Of course, to really see the maximum benefits, you need a framerate matching the strobe rate -- e.g. GPU capable of 120fps @ 120Hz or 100fps @ 100Hz.
(or 85fps @ 85Hz / 144fps @ 144Hz when nVidia G-SYNC enables 85Hz and 144Hz strobing)
There are additional benefits of G-SYNC, including G-SYNC's other stutter-free variable refresh rate mode (which has more motion blur but eliminates stutters/tearing).
