Flicker/PWM Dimming

DSC_0438 by Dr NCX, on Flickr

The HP 24 Envy, 25" & 27" HP CW/er/es/XW series monitors are not advertised as being Flicker Free even though they do not use LED PWM Dimming (read about the side effects), regardless of high or low the brightness is set. LED PWM Dimming was tested for using the Blur Busters Test UFO Blur Trail/PWM Test from 0-100% Brightness. The lack of PWM is a good thing since PWM or Flicker ruins motion clarity (example), and makes some people suffer from health issues such as headaches, and/or eyestrain.
