U kunt de helderheid van uw monitor beheren via defunctietoetsen op uw toetsenbord. Wanneer u op de toetsen voor het verhogen of verlagen van de helderheid drukt, verlaagt Windows 10 de helderheid met een bepaald niveau. Er is geen manier om de helderheidsniveaus te regelen wanneer u de speciale knoppen gebruikt. Als u fijnere controle wilt, moet u de schuifregelaar voor helderheid gebruiken. Als u de helderheidsniveaus wilt regelen wanneer u de helderheid met uw toetsenbord wijzigt, kunt u dit doen met een AutoHotkey-script.
SPOILER ALERT: Scrol omlaag en bekijk de videozelfstudie aan het einde van dit artikel.
Helderheidsverhogingsniveaus

}Plak helemaal aan het einde hiervan. Dit is het gedeelte van het script dat u zult aanpassen aan uw eigen behoeften. Het volgende wijzigt de helderheid via de toetsen Page Up en Page Down op uw toetsenbord. Het verandert met 10, d.w.z. wanneer u eenmaal op de toets Page Up tikt, gaat de helderheid tien niveaus omhoog.
Bewerk de niveaus naar wat je nodig hebt. U kunt dit bijvoorbeeld wijzigen in 1 en -1 om een betere controle over de helderheid te krijgen.
BS := new BrightnessSetter() PgUp::BS.SetBrightness(10) PgDn::BS.SetBrightness(-10)
Sla het script op met de AHK-bestandsextensie en voer het uit. Gebruik de toetsen die u hebt ingesteld om de helderheid aan te passen.
