Modifier le niveau d'incrément de luminosité de Windows 10

Je suis sur Windows 10 sur ThinkPad Lenovo x1 de Lenovo avec Intel (R) HD Graphics. Lorsque j'appuie sur la touche Fn + Luminosité, la luminosité augmente / diminue de 10. Je souhaite modifier cette valeur d'incrémentation en 1. La seule façon de procéder, pour autant que je sache, consiste à ouvrir la fenêtre de luminosité et à utiliser le curseur.

J'ai utilisé nircmd pour modifier la luminosité comme indiqué dans cette réponse .

Mais je ne sais pas pourquoi je ne peux pas utiliser cmdshortcutkey commande en nircmd.

}

BrightnessSetter_new() {
    return new BrightnessSetter()
}

4. Remplissez le code suivant et ajoutez ci-dessous le script

BS := new BrightnessSetter()

<increment hotkey>::BS.SetBrightness(<increment value>)
<decrement hotkey>::BS.SetBrightness(<decrement value>)

Exemple:

BS := new BrightnessSetter()

!Right::BS.SetBrightness(1)
!Left::BS.SetBrightness(-1)

!Right veux dire Alt + Right arrow key

!Left veux dire Alt + Left arrow key

Lisez la documentation AutoHotKey pour vous personnaliser.

5. Enfin, vous pouvez créer un raccourci pour le script et le placer dans le dossier de démarrage de Windows.

Pour ouvrir le dossier , presse Windows+R, entrer shell:startup, presse Enter.

J'utilise 3RVX pour modifier mon volume de 1% sous Windows 10. Je ne serais pas surpris que ce soit aussi une option de luminosité.
