There shouldn't be any flicker in any mode if you avoid monitors that use PWM for backlight control (which anyone who's sensitive to flicker probably should do)

There shouldn't be any flicker in any mode if you avoid monitors that use PWM for backlight control (which anyone who's sensitive to flicker probably should do). I was stupid enough to buy one with low frequency PWM (didn't have money for anything else at that moment) and "solved" the problem by setting brightness to 100% (which sets duty cycle to 100%), but it destroyed image quality.
