A very common method used to dim backlights on LCD monitors involves pulsing the backlight rapidly on and off to varying degrees,
something called PWM (Pulse Width Modulation). This can cause some users to experience headaches, eyestrain or general discomfort even after relatively short periods of monitor use (under an hour).
The AOC i2757Fm uses PWM (Pulse Width Modulation) to dim the backlight. This shouldn’t be of concern to most users, but those who know they are sensitive to flickering or are looking to avoid monitors that use PWM should bear this in mind
