We put ASUS VivoBook Flip 14 TP401 to several tests and quite frankly – the results were rather disappointing. Unfortunately, its panel is PW-modulated for all brightness levels except for the maximum one.
According to our equipment, the screen uses low-frequency PWM (1 kHz) which causes unnecessary eye and brain strain. As you may have learned from our other articles, the higher the frequency, the better.
Therefore, we strongly recommend setting the brightness to the maximum level as it is the only case when the screen of ASUS VivoBook Flip 14 TP401 doesn’t use PWM. You could also install our Health-Guard profile, which not only eliminates PWM but also limits the negative blue light emissions.
