Does the HP x27i use Flicker-Free or PWM-Free Backlight?

HP Recommended
HP x27i
Microsoft Windows 7 (64-bit)


Some websites list this monitor with the following features:


Backlight: white-LED, flicker-free, blue light filter



Now I have been looking at the official User Guide and the offical HP Specifications for this monitor and haven't found any Information regarding the flicker-free backlight.

So my question is:

Does the HP x27i officially use flicker-free / pwm-free (pulse-width-modulation) backlight ?

This is a very important issue to me and if this would not be the case I would buy a benQ or Viewsonic instead since they officially state in their Product Specifications that they sell flickerfree models.

The German HP Store list this Monitor as PWM-Free under Technische Daten, Flimmerfrei: Ja which means Flicker-Free: Yes.

Can someone at HP confirm this? I am seriously thinking about sending my monitor back. Nowadays every major Manufacturer avoids PWM-Dimming and every major review sites tests the monitors for PWM.
