Here is my honest answer..I own a 32D series from sony.
Personall I liked the 100hz feature very much...
Movie wise...It makes the motions in the movie you play on the screen 'extra smooth.'....it basically doubles the frames per second...you will somehow look at it a bit smoother hence it'll look somewhat 'artificial'..Whether artificial is bad or not depends entirely on one's 'taste' or prefernce...I liked watching Pirates BD with Motion plus turned on (normal setting).
But there's certain movie I prefer watching it with the option off...
When it come to games....
Again Some games I prefer it to be switched on and some off. Example of a game that I liked it to be switched on is Motorstorm...The game is running at 30fps...add Motion Plus...it becomes 60fps...hence smoother...
Some games is not suited to be 'motion plus'ed...because motion plus will sometimes introduces 'noise' in the video...hence I'll switch it off...
Most of the time I'll leave it on at Normal setting.
Ypu have to see it your selves to decide....It's totally falls back to one's preference....
Hmm, if this is the case.....welwitchia, and all owners of 40W400A, do you feel that when you watched fast paced movies such like anime, fast action movie, the movie seems not smooth ar?
