How can I check whether the monitor backlight is DC (direct current) driven or PWM (pulse width modulation) driven?


If your BenQ monitor supports the flicker-free technology, its backlight is driven by DC; otherwise, it is PWM driven.

To find out whether your BenQ monitor supports the flicker-free technology, please go to BenQ official product page for the required info. or contact your local BenQ customer care team for further verification.
