As per Aida 64 info, I have CMN N156HCA-EAB panel (Monitor ID CMN15E7). I'm need to know if any PWM (pulse-width modulation) as a method of regulating brightness is active on my monitor at any frequency? If positive what are the the frequencies where PWM is active and percentage? 
I’ve downloaded specification from panel-related website, it’s rather technical but I’m not a technician.  
If this matters, I have this panel installed on my laptop:

Acer Aspire 7 A715-76G-560W (NH.QMMEU.002)

I absolutely need to know if my monitor is flickering (and how much if positive) or is it flicker-free.
