Flicker/PWM Dimming

DSC_0385 by Deepinthesky Teslastorm, on Flickr

The Dell S2719DGF does not use LED PWM Dimming (read about the side effects), regardless of high or low the brightness is set.  LED PWM Dimming is tested for using the Blur Busters Test UFO Blur Trail/PWM Test from 0-100% Brightness.  The lack of PWM is good since PWM or Flicker ruins motion clarity (example), and can cause some people to suffer from health issues such as headaches, and/or eyestrain.
