אתה יכול לנהל את בהירות הצג באמצעות ה-מקשי פונקציה במקלדת. כשאתה מקיש על מקש ההגדלה או ההפחתה של בהירות, Windows 10 מפחית את הבהירות ברמה מסוימת. אין דרך לשלוט ברמות הבהירות כשאתה משתמש בכפתורים הייעודיים. אם אתה רוצה שליטה עדינה, תצטרך להשתמש במחוון הבהירות. אם ברצונך לשלוט ברמות הבהירות כשאתה משנה את הבהירות עם המקלדת שלך, אתה יכול לעשות זאת באמצעות סקריפט AutoHotkey.
התראת ספוילר: גלול מטה וצפה במדריך הווידיאו בסוף מאמר זה.

}בסוף זה הדבק את הדברים הבאים. זהו החלק של התסריט שתשנה בהתאם לצרכים שלך. להלן משנה את הבהירות באמצעות מקשי Page Up ו- Page Down במקלדת. זה משנה אותו ב- 10 כלומר, כאשר אתה לוחץ על מקש Page Up פעם אחת, הבהירות עולה בעשר רמות.
ערוך את הרמות לכל מה שאתה צריך. לדוגמה, אתה יכול לשנות את זה ל -1 ו -1 כדי לקבל שליטה טובה יותר על הבהירות.
BS := new BrightnessSetter() PgUp::BS.SetBrightness(10) PgDn::BS.SetBrightness(-10)
שמור את הסקריפט עם סיומת הקובץ AHK והפעל אותו. השתמש במקשים שהגדרת כדי להתאים את הבהירות.
