Also, just to know: how does this software works exactly ? It doesn't change real screen brightness right ?

Is there any risk of screen calibration modification ? Or damage ?

Anyway, it does the job better than anything that adjust real screen brightness setting.

Thanks a lot, works really well.
I prefered the % settings accessible like the other version though: this version seems only allow to set at start or with hotkeys.

Cordially,
Brak
