Vous pouvez gérer la luminosité de votre moniteur via letouches de fonction de votre clavier. Lorsque vous appuyez sur les touches d'augmentation ou de diminution de la luminosité, Windows 10 diminue la luminosité d'un certain niveau. Il n'y a aucun moyen de contrôler les niveaux de luminosité lorsque vous utilisez les boutons dédiés. Si vous souhaitez un contrôle plus fin, vous devrez utiliser le curseur de luminosité. Si vous souhaitez contrôler les niveaux de luminosité lorsque vous modifiez la luminosité avec votre clavier, vous pouvez le faire avec un script AutoHotkey.
ALERTE SPOIL: Faites défiler la liste et regardez le didacticiel vidéo à la fin de cet article.

Niveaux d'incrément de luminosité
Assurez-vous que AutoHotkey est installé sur votre système.
Ouvrez le Bloc-notes et collez-y les éléments suivants. Ce script a été écrit par l'utilisateur de Reddit yet_another_usr.

À la toute fin, collez ce qui suit. Il s'agit de la partie du script que vous modifierez en fonction de vos propres besoins. Les éléments suivants modifient la luminosité via les touches Page précédente et Page suivante de votre clavier. Il le change de 10, c'est-à-dire que lorsque vous appuyez une fois sur la touche Page précédente, la luminosité augmente de dix niveaux.
Modifiez les niveaux selon vos besoins. Par exemple, vous pouvez le changer en 1 et -1 pour obtenir un contrôle plus fin de la luminosité.
BS := new BrightnessSetter() PgUp::BS.SetBrightness(10) PgDn::BS.SetBrightness(-10)

Enregistrez le script avec l'extension de fichier AHK et exécutez-le. Utilisez les touches que vous avez configurées pour régler la luminosité.
