The PWM frequency of the IPS235V is 240 Hz. I measured it with a photo-transistor and sound card. The pulse width seems to be a linear function of the brightness:

- brightness=27: 50% PWM

- brightness=64: 75% PWM (see screenshot here - note the waveform is inverted)

- brightness=100: 100% PWM (no flicker)

The above numbers agree with this graph from the PRAD test:

Thanks a lot. It is a bit lower that I hoped. Will have that in mind.

And what is the PWM frequency?

Hi,
Only short, but very important question: is HP ZR22w more or less backlight flicker free (PWM flicker free)? This is very important for me.
Thank you.
