By relying on keyboard shortcuts for common tasks like brightness adjustment, you can reduce the risk of these conditions and maintain your overall well-being.
The Primary Suspects: Unveiling the Standard Brightness Shortcuts
Windows 10 typically relies on a combination of the Fn (Function) key and dedicated brightness keys located on your keyboard. These keys usually feature icons representing the sun, a lightbulb, or other symbols related to brightness. The exact placement of these keys varies depending on your laptop manufacturer, but they are commonly found in the top row, often labeled F1 through F12.
To increase brightness, you typically press the Fn key and the brightness-up key simultaneously. Conversely, to decrease brightness, you press the Fn key and the brightness-down key together. It’s a straightforward and efficient system.
However, some keyboards may not require the Fn key to be held down. In these cases, simply pressing the brightness keys will directly adjust the screen brightness. This is often configurable within your BIOS or laptop manufacturer’s settings. Check your laptop’s manual or the manufacturer’s website for specific instructions.
Troubleshooting the Standard Shortcuts: When Things Don’t Go as Planned
Occasionally, the standard brightness shortcuts may not function as expected. Several factors can contribute to this issue, including outdated drivers, incorrect settings, or hardware problems.
One common cause is outdated display drivers. Your display driver is the software that allows your operating system to communicate with your graphics card. If your driver is outdated or corrupted, it may not correctly interpret the brightness commands. Updating your display driver is a simple solution that often resolves the issue. You can usually find the latest drivers on the manufacturer’s website for your graphics card (e.g., Nvidia, AMD, or Intel).
Another potential culprit is incorrect power settings. Windows 10 includes various power plans that can affect display brightness. For example, the “Power Saver” plan may automatically dim the screen to conserve battery life. To ensure that your brightness shortcuts are working correctly, check your power plan settings and adjust them as needed. You can access these settings by searching for “Power Options” in the Windows search bar.
Finally, in rare cases, hardware problems may be responsible for the malfunctioning shortcuts. If you’ve tried all other troubleshooting steps and the problem persists, it’s possible that there is an issue with your keyboard or display adapter. In this situation, it’s best to consult with a qualified technician.

Furthermore, the Settings app allows you to enable or disable “Change brightness automatically when lighting changes.” This feature uses the ambient light sensor on your device to automatically adjust the screen brightness based on the surrounding environment. While this feature can be convenient, some users may find it distracting or prefer to manually control their brightness.
Command Prompt Power: Using the Command Line Interface
For advanced users, the Command Prompt offers a powerful way to control brightness using command-line commands. This method is particularly useful for automating brightness adjustments or integrating them into scripts.
To access the Command Prompt, search for “cmd” in the Windows search bar and press Enter. To adjust the brightness using the Command Prompt, you can use the PowerShell command.
Open Powershell and run the following command:
powershell
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,50)
Replace 50 with the desired brightness level (0-100).
This command directly controls the brightness level of your display. You can create batch files or scripts to quickly adjust the brightness to different levels based on your needs.
External Monitors: Adapting to Multiple Displays
If you’re using an external monitor with your Windows 10 laptop or desktop, the brightness adjustment process may be slightly different. In most cases, the standard keyboard shortcuts will only control the brightness of the primary display (usually the built-in laptop screen).
To adjust the brightness of an external monitor, you’ll typically need to use the monitor’s physical buttons or on-screen display (OSD) menu. These buttons are usually located on the front, side, or back of the monitor.
The OSD menu allows you to access various settings, including brightness, contrast, color temperature, and more. The specific layout and options available in the OSD menu will vary depending on the monitor manufacturer and model.
Some external monitors may also offer software utilities that allow you to control the brightness from your computer. These utilities typically provide a more user-friendly interface than the OSD menu. Check the monitor manufacturer’s website for available software downloads.
Third-Party Solutions: Exploring Advanced Brightness Control
In addition to the built-in brightness control methods in Windows 10, several third-party software applications offer advanced features and customization options. These applications can be particularly useful for users who require more granular control over their display brightness or who want to automate brightness adjustments based on specific conditions.
One popular third-party application is “f.lux.” This application automatically adjusts the color temperature of your display based on the time of day. During the day, it uses a cooler color temperature that is similar to daylight. At night, it gradually shifts to a warmer color temperature that is easier on your eyes. f.lux can help reduce eye strain and improve sleep quality, especially for users who spend long hours working on computers.
Another useful application is “DimScreen.” This application allows you to dim your screen beyond the minimum brightness level offered by Windows 10. This can be particularly helpful in very dark environments, where even the lowest brightness setting may still be too bright.
Finally, some applications allow you to create custom brightness profiles based on specific applications or activities. For example, you could create a profile that automatically dims the screen when you launch a video game or increases the brightness when you open a spreadsheet. These types of applications provide a high degree of customization and control over your display brightness.
Common Brightness Issues: Diagnosing and Resolving Problems
Even with a solid understanding of brightness shortcuts and adjustment methods, you may occasionally encounter issues that prevent you from controlling your screen’s brightness. Here’s a breakdown of common problems and how to address them:
Brightness slider missing: If the brightness slider is missing from the Action Center or Settings app, it could be due to outdated display drivers or a problem with your graphics card. Try updating your display drivers and restarting your computer.
Brightness keys not working: If your brightness keys are not functioning, ensure that the Fn key is enabled (if required). Also, check your keyboard settings to see if the brightness keys have been remapped. Outdated drivers can also cause this issue.
Brightness automatically changing: If your brightness is automatically changing, disable the “Change brightness automatically when lighting changes” feature in the Settings app. Also, check your power plan settings to ensure that they are not interfering with your brightness preferences.
External monitor brightness not adjustable: If you’re unable to adjust the brightness of your external monitor, ensure that the monitor is properly connected and that the correct input source is selected. Try using the monitor’s physical buttons or OSD menu to adjust the brightness.
