PWM (Pulse Width Modulation) and DCM (Direct Current Modulation) have never been stated in any of our sales specifications or in the online monitors User's Guide specifications. The inference is that if you see any of these "RGB-LED/W-LED/LED backlight/LED edgelight" in the User's Guide descriptions, then the monitor is using PWM.
