Flicker/PWM Dimming

DSC_0024 by Dr NCX, on Flickr

The LG is advertised as Flicker Safe, which means it does not use back-light flicker or LED PWM Dimming (read about the side effects), regardless of high or low the brightness is set.  I checked for and did not see LED PWM Dimming with the Blur Busters Test UFO Blur Trail/PWM Test with 0-100% brightness settings in the menu. The lack of PWM is a good since PWM or Flicker ruins motion clarity (example), and makes some people suffer from health issues such as headaches, and/or eyestrain.
