HP ProBook 440 G5’s TN display doesn’t use PWM only at maximum brightness
We put the HP ProBook 440 G5 to several tests the results of which were rather contradictory. Starting with the bad news – the TN display uses PWM from 0 to 99% brightness that may cause unnecessary strain on some users’ eyes.
However, there is also a positive side – the display flickers at an acceptable frequency (1 kHz) which reduces the negative effect to a certain extent making the device relatively comfortable for a prolonged period of time. If this happens to be an issue for you, we have a solution to the problem and it is our Health-Guard profile which eliminates PWM and also reduces the negative blue light emissions.
