How to activate DC-Dimming option in Pixel Experience?

[danisimo2]

I use now the last ROM of Pixel Experience, but in the screen menu there is no a anti- flicker or DC-Dimming option to reduce the visual fatigue in my eyes, i need help to activate this option.

I didn't see this option in other roms than MoKee and Derpfest.
