Screen brightness is one of the leading causes of eye strain and headaches. Knowing how to adjust the screen brightness on your Windows computer is vital for your eye’s health. If you’re unsure, don’t worry; our guide will show you how to change brightness on Windows 10.

Before we start, we want to point out that these methods mainly apply to laptop use. If you are on a Windows desktop, you can follow the same steps for a similar result.

Method 1: Change In Settings

1: Press the Windows Key + I

Press the Windows key and I at the same time to bring up the settings menu.

2. Select System, then Display

By default, the System option should be showing on the settings screen, but if not, select System on the left-hand menu. Then select Display which should be the very first option on the list.

3. Use The Brightness Slider

Moving the slider to the ight will dim the screen, and to the right will make it brighter.

In the Display menu, you will see a blue slider bar across from the word Brightness. Use this slider to adjust the brightness of your screen.

Method 2: Adaptive Brightness

To change screen brightness, follow the first two steps of Method 1, but the third step will vary.

1: Press the Windows Key + I

To quickly bring up the settings menu, press the Windows key and I simultaneously.

2. Select System, then Display

Display should be the very first option on the list.

By default, the System option should be showing on the settings screen, but if not, select System on the left-hand menu.

3. Click on the Brightness

For this method, click on that arrow to reveal two options.

Next to where we used the brightness slider in method 1, there is a downward-facing arrow.

4. Check both boxes

select both of these boxes for optimal results.

In this little menu, there are two checkboxes. One will read Change brightness automatically when lighting changes. And the other will read Help improve battery by optimizing content shown and brightness.

Method 3: Adjusting with the Action Center

Instead of going into settings, use the keyboard shortcut.

Bring up the Action Center by pressing the Windows Key + A simultaneously. Here you will see some options like Network and Bluetooth. What we are looking for is the brightness slider. This acts the same way as the slider bar in method 1. Slide to the left to brighten the screen and slide to the right to dim the screen.

Congratulations, you know the three methods to change your screen brightness on Windows 10 and 11. If you don’t feel it, your eyes will thank you in the long run.
