In a report on LCD vs plasma wars the New York Times stumbles into CNET reviewers checking out the Vizio 42″ LCD HDTV:
At CNET’s test center in Manhattan, Mr. Miller and Mr. Katzmaier were reviewing the 42-inch Vizio L42 HDTV L.C.D. ($1,600). To optimize picture quality, they reduced the backlight intensity to 10 on a scale of 1 to 100. (The default is 90.)
I tried setting the backlight to 10 on the DVD I was watching through the HDMI connection, and got a pretty bleak and darkened picture, so CNET experience did not quite work for me. Turning the backlight to maximum value of 100 produced a pretty good effect and brightened the LCD picture.
