Jak kontrolować poziomy jasności w systemie Windows 10

Możesz regulować jasność monitora przy użyciu klawiszy funkcyjnych na klawiaturze. Po naciśnięciu klawiszy do zwiększania lub zmniejszania jasności, system Windows 10 zmienia jasność o ustalony poziom. Niestety, nie ma opcji szczegółowej kontroli poziomów jasności, gdy korzystasz z tych dedykowanych przycisków. Aby uzyskać lepszą kontrolę, musisz użyć suwaka jasności. Jeżeli chcesz dostosować poziomy jasności, korzystając z klawiatury, możesz to zrobić za pomocą skryptu AutoHotkey.

OSTRZEŻENIE SPOILERA: Przewiń w dół, aby obejrzeć samouczek wideo na końcu artykułu.

Regulacja jasności

Upewnij się, że AutoHotkey jest zainstalowane na twoim komputerze.

Na końcu dodaj następujące linie. To jest ta część skryptu, którą możesz dostosować do swoich potrzeb. Poniższe instrukcje zmieniają jasność za pomocą klawiszy Page Up i Page Down na klawiaturze, co pozwala na zwiększenie jasności o 10 poziomów za jedno naciśnięcie klawisza Page Up.

Możesz edytować wartości, aby lepiej odpowiadały twoim potrzebom. Na przykład, zmieniając je na 1 i -1, zyskasz większą precyzję w regulacji jasności.

BS := new BrightnessSetter()

PgUp::BS.SetBrightness(10)
PgDn::BS.SetBrightness(-10)

Zapisz skrypt z rozszerzeniem AHK i uruchom go. Użyj skonfigurowanych klawiszy, aby dostosować jasność.
