My parents have a 60 Hz LCD TV that has adjustable levels of motion smoothing. I can tell when the motion blurring is turned on because some parts of the movies just don't look "right". But, most of my family can't tell the difference - they just don't see anything change.
Some of my readers ask me what a "Serial Port" is. The answer is: I don't know. Is it some kind of wine you have with breakfast?
