How to change the screen brightness in Windows 10, It is very important to set the screen brightness on the computer to the optimal level. Below you will find 5 different ways to change the screen brightness in Windows 10.
Change the screen brightness in Windows
If you experience eye fatigue while using the computer, it is most likely caused by not adjusting the brightness of the computer screen according to the surrounding lightning conditions.
Therefore, we provide the following different methods to increase or decrease the screen brightness on a Windows 10 computer.
Use action center
An easy way to increase or decrease the brightness of the computer screen is to go to the action center.
Click on the Action & Notification icon and adjust screen brightness by using the brightness control toggle in Action Center.

You will see the brightness of the screen increasing when you move the toggle to right and decreasing when the toggle is moved to the left.
Use Mobility Center
Another way to change the brightness of the computer screen is to go to Windows Mobility Center.
Right-click on the Start button and click on Mobility Center. Once you are in Mobility Center, drag the Brightness bar to the left or right, to adjust the screen brightness on your computer.

Use Settings
The traditional way to change the screen brightness in Windows 10 is to open “Settings” on your computer.
Go to Settings > System > select Display in the left pane. In the right-pane, scroll down and drag the Brightness bar to change the brightness level on your computer.

Use Keyboard
If you are using a Laptop, look for the Brightness icon on Function Keys (F1 to F12). Once, you locate those keys, you can quickly change the screen brightness on your computer by pressing Fn + the Brightness key.

This is perhaps the quickest way to change screen brightness in Windows 10.
Automatically adjust the brightness to save battery life
Although the shiny bright screen looks good, it will eventually consume a lot of battery life. Therefore, Windows 10 provides an option to automatically adjust the brightness to save battery life.
Go to Settings > System > click on Battery in the left pane. In the right pane, select Lower Brightness while in the Battery Saver mode option.

After selecting this option, as long as the battery power on the computer drops to 20%, the computer will automatically lower the screen brightness.
Hope to change the screen brightness in Windows 10!
