Samsung Flicker/PWM Dimming

Samsung 43NU7100 50 Back Light vs  30 by Deepinthesky Teslastorm, on Flickr

The Samsung uses low frequency LED PWM Dimming (read about the side effects), when the back-light is set to 49/50 or lower.  LED PWM Dimming is tested for using the Blur Busters Test UFO Blur Trail/PWM Test from 0-100% Brightness, and used this testing method developed by TFT Central.  The two pictures above are of the 50/50 back-light photo and 30/50.

PWM or Flicker ruins motion clarity (example), and can cause some people to suffer from health issues such as headaches, and/or eyestrain.
