I've been testing LCD monitors consistently for the past two years. In that time, I've run various tests designed to evaluate a monitor's response time. I've used games, movies, and the occasional scientific test to confirm if a manufacturer's claimed response time is accurate.
To be perfectly honest, I have a very difficult time seeing motion blur in movies and games. In fact, I'm not sure I've seen it any repeatable evidence of it on a modern monitor during a game or movie.
So it should go without saying that DisplayMate's recent findings on LCD response times come as no big shock to me. The findings come via an article by DisplayMate founder Raymond Soneira.
Here are Soneira's major conclusions based on tests conducted by DisplayMate on LCDs from major manufacturers.
1. A manufacturer's claimed response time specifications are not a scientifically accurate or a meaningful indicator of picture blur.
The motion blur DisplayMate measured on the HDTVs tested was more than 40 milliseconds. According to the article, this is more than a factor of 10 greater than the manufacturer's published specifications.
2. LCD manufacturers have made a big deal about refresh rates in the last couple of years with the jump from 60Hz to 120Hz and now 240Hz. CNET's own David Katzmaier suspected that benefits with the jump to 240Hz were dubious already, but here's more evidence to back it up. … Read more
