Step by Step Tutorial: Adjusting Brightness Settings in Windows 10

Adjusting the brightness settings in Windows 10 is a breeze, and the following steps will guide you through the process.

Step 1: Open the Action Center

Click on the Action Center icon located on the bottom right corner of your screen.
The Action Center is the place where you can find quick settings and notifications. It’s represented by a speech bubble icon next to the system clock.

Step 2: Adjust the Brightness Slider

Locate the brightness slider and adjust it to your desired level.
The brightness slider is a quick way to adjust your screen’s brightness without having to go through any menus. Simply click and drag the slider left or right to decrease or increase the brightness.

Step 3: Access the Settings Menu for More Options

For more advanced options, open the ‘Settings’ menu by clicking on the Start Menu and selecting the gear icon.
In the ‘Settings’ menu, you can find more in-depth options for adjusting your screen’s brightness. This includes setting automatic adjustments based on battery level or ambient light conditions.

Step 4: Navigate to Display Settings

In the Settings menu, select ‘System’ and then ‘Display.’
The ‘Display’ settings allow you to customize your viewing experience, including brightness, resolution, and night light settings.

Step 5: Use the Brightness Slider Within Display Settings

Adjust the brightness slider within the Display settings to fine-tune the brightness.
This slider functions similarly to the one in the Action Center but provides a more precise level of control. Adjusting the brightness here will also give you access to other display-related settings.

After completing these steps, your screen brightness will be adjusted to your preferred setting. Depending on your specific needs and environment, you may find yourself adjusting the brightness regularly, but with these simple steps, it’s a quick and painless process.
