Anybody know why LCD's suffer from motion blur?

The biggest problem with LCD's is because the pixels can't turn on & off as fast as a plasma's can. It doesn't matter how fast the refresh is or how many (120, 240) hertz if the pixels can't respond as fast. I think the LCD manufacturers try to keep this info (pixel turn on/off speed) hushed so they can go on fooling the public as to (supposedly) how superior the spec's are for LCD. I believe in "seeing is believing", not just spec's on paper! If the picture doesn't look good who cares what the spec's are.

They advertise the pixel response time which is a measure of the turn on/off time. The newer ones can get down to the 2ms range, but that is still much slower than plasmas. However, most people don't notice the pixel response blur on the very fast LCDs anymore. If someone does, they would probably be better off with a plasma.

But even with a plasma there can still be motion blur in the source. Additionally, watching broadcast programming there will be macroblocking in fast motion. For me those are more annoying because I know they are the fault of the delivery system, not my TV.
