What Are The Ways To Change Brightness In Windows 11?

Using Keyboard Shortcuts

The quickest way to adjust brightness on most laptops is by using the dedicated keyboard shortcuts.

Look for keys on your keyboard that have a sun or lightbulb icon. These are usually located on the function keys (F1, F2, etc.).
Press and hold the “Fn” key (if required) along with the brightness up or down key.
Observe the brightness level indicator on your screen to confirm the adjustment.

Adjusting Brightness Through Settings

Windows 11 offers a built-in settings menu to control display brightness.

Open the Settings app by pressing Windows key + I.
Click on System, then select Display.
In the Display settings, find the Brightness & color section.
Use the slider to adjust the brightness level to your desired setting.

Using the Action Center

The Action Center provides quick access to frequently used settings, including brightness.

Click on the Action Center icon in the taskbar (it looks like a speech bubble or notification icon).
Locate the brightness tile. It may display a percentage or a sun icon.
Click the brightness tile to cycle through different brightness levels or use the slider that appears when you hover over the icon.

Changing Brightness with Adaptive Brightness

Windows 11 has an adaptive brightness feature that automatically adjusts the screen brightness based on ambient lighting conditions.

Open the Settings app (Windows key + I).
Click on System, then select Display.
Click on Brightness.
Toggle the Change brightness automatically when lighting changes option to turn adaptive brightness on or off.

Utilizing the Mobility Center (Laptops Only)

The Mobility Center is a feature primarily found on laptops that provides quick access to various settings, including brightness.

Press Windows key + X to open the Quick Link menu.
Select Mobility Center from the list.
Use the brightness slider to adjust the screen brightness.

Adjusting Brightness Through Power Options

You can configure different brightness levels for when your device is plugged in versus running on battery.

Open the Control Panel.
Click on Hardware and Sound, then select Power Options.
Next to your selected power plan, click on Change plan settings.
Adjust the Display brightness sliders for both “On battery” and “Plugged in” modes.
Click Save changes.

Using Third-Party Apps

Several third-party applications offer more granular control over screen brightness and color temperature.

Twinkle Tray: Allows you to control the brightness of multiple monitors.
f.lux: Automatically adjusts the color temperature of your display based on the time of day.
SunsetScreen: Similar to f.lux, adjusts color temperature to reduce eye strain.

Tips For Optimal Brightness

Consider the Ambient Lighting: Adjust your brightness according to the lighting in your environment. Lower brightness is better for dark rooms, while higher brightness is needed in bright environments.
Conserve Battery: Lowering the brightness can significantly extend your laptop’s battery life.
Reduce Eye Strain: Adjusting brightness and color temperature can help reduce eye strain, especially during prolonged use.
Use Adaptive Brightness Wisely: While convenient, adaptive brightness may not always be accurate. Adjust it manually if needed.
