U2913WM came with a fantastic horizontal plus screen, but rumors are around that it's PWM (Pulse Width Modulation) dimming and it hurts eyes by noticeable flicker. So does the monitor carry a PWM dimming or not?
The specifications state, "LED edgelight system" which does use PWM (Pulse Width Modulation) dimming.

Thanks, Chris. I checked user manuals and some other reviews on u2913wm, u2713hm and other dell ultrasharp monitors. U2713hm, which is not PWM dimming (check the link below), is stated "edgelight" in it's specification as well.
Seems the "LED edgelight system" may not be a decisive evidence to PWM dimming. But the author posted an another review on u2913wm, only confirmed in text that this monitor was PWM free (link below). Hope it's true :)
