Interesting article on LCD TV refresh rates, introducing the "Soap Opera Effect". Essentially, higher refresh rate LCD TVs have an effect that smooths the video by inserting additional frames. This feature can be turned off:

This motion "whatever" was ostensibly developed to help decrease apparent motion blur on LCDs. All LCD TVs have difficulty with motion resolution. Which is to say, any object onscreen that's in motion will be less detailed (slightly blurry) compared with that same object when stationary. High-refresh-rate LCDs (120Hz and 240Hz) were developed to combat this problem. Check out "What is refresh rate" for a more in-depth description of this. The short version: in order for high-refresh-rate TVs to be most effective, they need new, real frames to insert in-between the original frames.


Up until recently SOE has been an LCD-only "issue." In the effort to make plasmas more competitive in a retail store, motion smoothing circuitry has found its way into plasmas. Because plasma TVs don't suffer from the motion blur problems that LCDs have (or at least, not to the extent), motion smoothing is largely superfluous. For that matter, plasmas aren't increasing their refresh rates to insert new frames, so all that's really happening is the TV is creating new frames to insert in-between the film frames, just to make the motion smoother.
