Lenovo’s ideapad 120S (11”) screen is relatively harmless to your eyes
Starting off with the bad news – the display uses PWM (up to 70 cd/m2) for regulating the brightness of the screen resulting in the so-called screen flickering effect. However, on a more positive note, the screen flickers at high frequencies making it comfortable for continuous work as it wouldn’t have such a negative impact on most users.
However, if this is a worrying fact 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.
