Why each option
On laptops, display brightness is most directly and quickly adjusted using the function (Fn) key combined with a dedicated brightness hotkey on the keyboard.
Device Manager manages hardware drivers and does not provide a brightness adjustment control panel.
The BIOS manages firmware-level hardware settings and does not include display brightness controls for the operating environment.
Laptop keyboards include a dedicated Fn key that, when pressed in combination with labeled function keys (e.g., F5/F6), sends hardware-level signals to adjust backlight brightness instantly. This is the standard and most accessible method, designed specifically for mobile display control without navigating software menus.
Video display driver settings can affect resolution and color profiles but are not the primary or most direct method for adjusting backlight brightness.
