The screen brightness on a computer is one of the factors that affects the eyes a lot. Working continuously at high brightness can lead to eye strain and eye strain, as well as shorten your laptop’s battery life.
In the article below, apkody will guide you on 10 ways to adjust your Windows 10 screen brightness to protect your eyes and extend your laptop’s battery life.
Adjust screen brightness for desktop
On a tree machine, a separate screen, you usually won’t find the option to adjust the brightness of your computer’s screen in the settings, like on a laptop from the notification center. Usually you have to use physical buttons located on the edge of the screen (usually the side or bottom edge) to make adjustments.
Since each screen has a different button layout, it’s hard to be specific. Basically, you press the button, find the Brightness option and increase and decrease its value to increase or decrease screen brightness.
Some high-end monitors will have a dedicated button to adjust the brightness (on the front or side of the screen). If your PC monitor doesn’t have this button, try pressing the button and looking at each menu. See the onscreen manual to find it faster.
Adjust screen brightness for laptop
Adjust screen brightness with keyboard
Most laptop keyboards have an on-screen brightness adjustment key that quickly increases and decreases brightness. Typically, these keys are located in the F keys (that is, from F1 to F12) or the left and right navigation keys. To adjust the screen brightness, find the appropriate icon – usually a sun symbol or something similar – and press the key.
These are usually function keys, which means you have to hold down the Fn key on the keyboard, usually near the bottom left corner of the keyboard, while pressing them.
If your laptop doesn’t have its own dimmer keys, here’s how to adjust screen brightness.
Adjust screen brightness with Action Center
- Click the Action Center icon in the lower right corner of the screen to open it.
- On the Action Center panel, click the Brightness tile as shown below to increase or decrease screen brightness. If you don’t see Tile Brightness, click the expand button.
For the latest version of Windows 10, the screen brightness adjustment bar in Action Center is located just below the function, usually at the bottom. Drag the slider to the left to decrease screen brightness, or to the right to increase screen brightness.
Adjust screen brightness from Settings
Press Windows+I keys to open Settings and go to System > Display. Under Brightness and Color, use the Change Brightness slider. Moving to the left darkens the screen, while moving to the right brightens the screen.
If the slider is not available, there are 2 cases. If you are using an external monitor, use the buttons on it to change the brightness. If not, the display driver needs to be updated.
To do this, press Windows key+X and click Device Manager. Expand Display Adapters and right-click the graphics card. Click Update Driver and follow the wizard.
Adjust screen light using Control Panel
Your brightness may vary depending on whether the computer is charging or the battery is low. To save battery life, set the brightness level to dim when the device is not plugged in.
To do this, press Windows key+R to open Run, type Control Panel and click OK. Go to Hardware and Sound > Power Options and click Change plan settings next to the selected option.
Use the Adjust Schedule Brightness sliders to set the Battery On and Plugged in levels. When done, click Save Changes.
Adjust screen light using Windows Mobility Center
In addition to the above methods of changing the screen brightness, you can also change this feature through Windows Mobility Center.
- Go to the search bar on Windows and search for the keyword Mobility Center.
- Click to open Windows Mobility Center.
- Use the slider in the Display Brightness section of the window that appears to adjust the screen brightness.
Automatic brightness adjustment to increase battery life
Lowering the brightness can help extend battery life. Windows 10 has a battery saver feature that automatically reduces brightness when enabled.
To enable this feature, press Windows key+I to open Settings and go to System > Battery, scroll down to Battery Saver settings.

Finally, tick Reduce screen brightness in battery saver mode.
Adjust brightness with Windows 10 similarity feature
Ideally, the screen brightness should match the ambient light. One way to ensure this is to automatically change the brightness based on ambient light.
This feature is only enabled if the device has a brightness sensor. To enable it, press Windows key+I to open Settings and go to System > Display. If you see the brightness change automatically when the lights change, switch to On mode. If you don’t see this option, you don’t have a sensor.
A better way to adjust is through the control panel, as you can set it up according to your power plan. See Section 4 on how to do this.
Adjust screen brightness with shortcut
Here are two shortcuts for adjusting brightness settings:
- Shortcut 1: You can quickly adjust the brightness through the action center icon on the taskbar (or press Windows key + A). Use the brightness slider to adjust. The more you move to the right, the brighter the screen.
If you don’t see the icon, press Windows key+I, go to System > Notifications & Actions > Edit Your Quick Action, and click Add > Brightness > Done.
- Shortcut 2: Use a third-party utility called Windows 10 Brightness Slider. This lightweight utility adds a brightness icon to the system tray, which you can then click to adjust the brightness on the slider, the same way the volume icon works.
Go to the project on GitHub, download the file and open it. It will automatically go to the system tray. If you want it to always be there, right-click the icon and select Run At Startup.
Adjust screen brightness with PowerShell
You can also use the almighty PowerShell to change the screen brightness in Windows 10. Open PowerShell by typing “powershell” in the search field on the taskbar, then click Windows PowerShell.
To change the brightness, enter the following command:
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,**brightnesslevel)
Replace brightnesslevel with the desired percentage (%) value for screen brightness, in the range 0 to 100. For example, to set the brightness to 70%, enter the following command:
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,70)
After pressing Enter, the brightness will adjust to your liking.
Adjust screen brightness automatically
Adjust brightness when charging automatically
You can set different screen brightness levels on your laptop or tablet depending on whether it is plugged in or not. For example, you can set it to a high brightness level when plugged in and a lower brightness level when running on battery power. Windows will then automatically adjust your brightness.
To adjust the brightness in this way, open the control panel. Select Hardware and Sound > Power Options, then click the “Change plan settings” link next to the power plan you’re using. You may be using a balanced power plan.
Configure different screen brightness levels for “On battery” and “Plug in” in Adjust Plan Brightness. This setting is related to your power plan. If desired, you can configure different levels of screen brightness for different power plans and switch between them (though this isn’t strictly necessary).
Automatically adjust brightness based on remaining battery life
You can also automatically adjust the display’s backlight based on the laptop or tablet’s remaining battery life. On Windows 10, you can use Battery Saver to do this. Open the Settings app and select System > Battery.
Make sure the “Reduce screen brightness in battery saver mode” option is enabled, then select the percentage you want battery saver to use. When power saver is activated at this level, power saver will reduce the backlight and save you energy. By default, Battery Saver works when you have 20% battery remaining.
Unfortunately, there is no way to adjust the exact brightness level selected by the power saving mode. You can also manually enable this feature via the battery icon.
How to Automatically Adjust Brightness Based on Ambient Light
Many modern laptops and tablets have ambient light sensors that work like the sensors on smartphones and tablets. Windows can use this sensor to automatically increase screen brightness when you’re in a bright area, and decrease the brightness when you’re in a dark room.
This is convenient, but some people find it also gets in the way. It can automatically decrease or increase the screen brightness when you don’t need it, but you may need to manage the brightness manually using the settings above.
To enable or disable this feature on Windows 10, open the Settings app, select System > Displays. Enable or disable the “Automatically change brightness when lighting changes” option. You will only see this option if your device has an ambient light sensor.
You can also change this setting through the control panel. Open Control Panel, select Hardware and Sound > Power Options, click Change plan settings next to the power plan you’re using, and then click Change advanced power settings.
Expand the Display section here, then expand the Enable Adaptive Brightness section. The options here let you control whether to use adaptive brightness when on battery or when plugged in. For example, you can turn this feature off when plugged in and turn it on when running on battery power.
Adjust screen brightness with video card control software
In addition to the methods available on your device, you can also use third-party software to adjust the brightness of your computer screen. Screen brightness adjustment software is often designed to easily adjust, create shortcuts…
You can refer to one of the following software:
- Twinke Tray Brightness Slider (easy to use, adjustable for multiple monitors)
- Desktop lighter
- F.lux (capable of automatically adjusting screen brightness across time zones, time and detecting ambient light)
Most of these software are very easy to use, you just need to download, unzip (if it is a compressed file), and then run the installation file (usually .exe). After installation, you can adjust the brightness of your computer screen immediately.
