Why the SW series of the BenQ monitor backlight is PWM (pulse width modulation) driven?

08-11-2023

Most of BenQ's monitors that support flicker-free technology use DC-driven backlight, and for some SW models that do not support the flicker-free technology, they use PWM-driven backlight instead. The reason to use PWM is that different LED technology may require different ways to drive the backlight to achieve accurate color performance. For models that do not use flicker-free panels, they will need PWM to drive the backlight to achieve that goal. If you still have concerns, please contact your local BenQ support team for more verification.
