Buying an LCD HDTV just got a whole lot easier. According to Dr. Raymond M. Soneira, of DisplayMate, the quest for minimal response times is as foolish as comparing raw processor speeds. It’s the real world that matters, and for live video mid- to high-range LCDs perform just fine regardless of their rated response times.
Dr. Soneira compared the motion blur characteristics of eight LCDs and two Plasmas against a Sony Professional HD Trinitron Studio monitor, using a battery of motions tests from the proprietary DisplayMate Multimedia with Motion Bitmaps Edition software. His conclusion: “there was essentially no visually detectable motion blur on any of the LCD HDTVs in all of the extensive live video content that we assembled.” Motion blur is more likely a subjective rather than an objective phenomenon.
The good news from this report is it isn’t necessary to ‘buy up’ to 120 Hz or higher refresh rates, strobed LED backlighting, or advanced motion blur processing (which Dr. Soneira claims can introduce “ugly motion artifacts”). Stick with a reputable brand, in the mid- to high-range, without regard to response times, and you’ll be fine.

Most of the time I see these effects its during live events. I guess that has to do with the camera covering the event?

I think what alot of people see watching live events is the crappy compression algorithm that they use to convert the feed to 1080/720p. TV shows don't tend to have the same blur and aliasing issues that sporting events do, but for tapes shows they have time to clean up the video and compress it properly, something there just isn't time for on a live feed.

The link was about gaming on computer monitors. The article was about HDTVs, and presumably, watching movies and tv shows. Entirely different scenario.
