Вы можете управлять яркостью монитора с помощью функциональных клавиш на клавиатуре. Когда вы нажимаете клавиши увеличения или уменьшения яркости, Windows 10 снижает яркость на определенный уровень. При использовании специальных кнопок невозможно контролировать уровень яркости. Если вы хотите более точный контроль, вам придется использовать ползунок яркости. Если вы хотите контролировать уровень яркости при изменении яркости с помощью клавиатуры, вы можете сделать это с помощью скрипта AutoHotkey.
ОПОВЕЩЕНИЕ СПОЙЛЕРА: прокрутите вниз и посмотрите видеоурок в конце этой статьи.
Уровни увеличения яркости
Убедитесь, что в вашей системе установлен AutoHotkey.

В самом конце вставьте следующее. Это часть сценария, которую вы измените в соответствии со своими потребностями. Следующее изменяет яркость с помощью клавиш Page Up и Page Down на клавиатуре. Он изменяет его на 10, т.е. когда вы нажимаете кнопку Page Up один раз, яркость повышается на десять уровней.
Отредактируйте уровни так, как вам нужно. Например, вы можете изменить его на 1 и -1, чтобы получить более точный контроль над яркостью.
BS := new BrightnessSetter() PgUp::BS.SetBrightness(10) PgDn::BS.SetBrightness(-10)
Сохраните сценарий с расширением файла AHK и запустите его. Используйте настроенные вами клавиши для регулировки яркости.
