If you’re struggling with the Windows 10 Night Light feature not working as it should, you’re not alone. This problem has left many users in the dark, pun intended, leading to discomfort while using their devices at night. Whether it’s causing headaches or affecting your sleep patterns, addressing the Night Light issue can significantly enhance your experience with your Windows system. In this article, we will delve into common reasons why the Night Light may not be functioning, along with practical, step-by-step solutions to get it working again.
Understanding Windows 10 Night Light
Before we jump into the solutions, let’s first understand what the Night Light feature is and why it’s important. The Night Light function is designed to reduce the amount of blue light emitted by your screen, which can disturb your sleep if you’re using your device late into the night. Blue light has been shown to interfere with the production of melatonin, a hormone responsible for regulating sleep.
This feature allows you to adjust the color temperature of your display to a warmer tone, thereby making it easier on the eyes during nighttime use. Unfortunately, like all technology, Night Light can experience issues that prevent it from working correctly, but luckily there are several steps you can take to address these problems.
Common Reasons Why Night Light Isn’t Working
Night Light may stop functioning for various reasons, including:
Graphics Driver Issues
Your computer’s graphics drivers play a critical role in the operation of many display features, including Night Light. If your drivers are outdated or corrupted, you may experience issues.
Windows Updates
Sometimes, after a Windows update, certain features may behave unexpectedly. The Night Light setting could be one of the features affected.
Display Settings Configuration
Improper configuration of your display settings may also prevent Night Light from functioning correctly. For instance, if you’re using multiple monitors, make sure to check the settings for each display.
Power Settings
Certain power settings can affect how Night Light behaves, particularly if you’re using a laptop. If your power plan is configured to save energy, it may limit some functionalities, including Night Light.

What is the Night Light feature in Windows 10?
The Night Light feature in Windows 10 is designed to reduce eye strain during the evening by adjusting the color temperature of your screen. It tints the display to warmer tones, which can help alleviate the harsh blue light that may interfere with your sleep cycle. This feature can be scheduled to activate automatically at specific times, typically around sunset.
By using the Night Light feature, users can enjoy a more comfortable viewing experience in low-light conditions. This is particularly beneficial for those who spend extended periods looking at their screens, as it helps create a more relaxing environment in the evening hours.
Why is my Night Light not turning on?
If your Night Light feature is not turning on, it could be due to various reasons. One common issue is that the feature may not be enabled in the settings. To check, go to Settings > System > Display and ensure that the Night Light toggle is switched on. If it’s already enabled but not working, a system restart might resolve the temporary glitches affecting the feature.
Another possibility is that your graphics drivers are outdated or incompatible. An outdated driver may hinder the proper functioning of display settings, including the Night Light feature. Check the manufacturer’s website to find the latest drivers for your graphics card and install them to see if that resolves the issue.
How can I manually enable Night Light in Windows 10?
To manually enable Night Light, start by navigating to the Settings menu. Click on “System,” and then select “Display.” There, you will find the option for Night Light. Simply toggle the switch to turn it on. You can also click on “Night light settings” to adjust the color temperature and set a custom schedule.
Additionally, you can easily activate Night Light from the Action Center. Click on the notification icon located in the taskbar, and you should see the Night Light button. If it’s not visible, you may need to expand the quick actions by clicking “Expand.” Clicking the Night Light icon will turn it on or off immediately, providing a quick and convenient way to manage its settings.
What should I do if my Night Light settings are greyed out?
If the Night Light settings are greyed out, it might indicate a compatibility issue with your hardware or software. First, ensure that your display supports this feature since some older monitors may not. Checking for system updates can also be beneficial, as Microsoft often releases patches and updates that may impact functionality.
In some instances, you may need to reinstall the display drivers or roll back to an earlier version. Go to Device Manager, locate your display adapter, and check for any updated drivers. If an update triggered the issue, rolling back might help regain access to the Night Light settings.
Can third-party software conflict with Night Light?
Yes, third-party applications, especially those related to display management and screen customization, can conflict with Windows 10’s Night Light feature. Programs like f.lux or custom screen color management tools may interfere, causing Night Light to malfunction or not show the expected results. To troubleshoot, consider disabling or uninstalling these applications temporarily.
If you suspect third-party software is the root cause, try running Windows in Safe Mode. In Safe Mode, only essential system drivers are loaded, which can help you identify if a third-party application is causing the issue. If Night Light works correctly in Safe Mode, it’s likely that an installed application is conflicting with the feature.
What do I do if my graphics driver is not up to date?
If you discover that your graphics driver is not up to date, the best course of action is to update it. You can do this by using the Device Manager. Right-click the Start button, then select Device Manager from the menu. Expand the “Display adapters” section, right-click your GPU, and select “Update driver.” You can choose to search automatically for updated driver software.
Alternatively, you can visit the manufacturer’s website directly—like NVIDIA, AMD, or Intel—to download the latest driver version. Software from the manufacturer often contains optimizations and fixes specific to their graphics chips. After installing the updated driver, restart your computer to apply the changes, and check if the Night Light feature is working properly again.
Can I schedule the Night Light to turn on and off automatically?
Yes, Windows 10 allows you to schedule Night Light to turn on and off automatically. This feature enables you to set specific times when the Night Light will activate, based on your preferences. Navigate to Settings > System > Display, then click on “Night light settings.” Here, you’ll find an option to set a schedule for the feature.
You can choose to have Night Light activated during sunset and deactivated at sunrise based on your geographical location, or you can set custom times. Scheduling Night Light helps ensure that your screen is adjusted to reduce eye strain during the evening hours without needing to remember to turn it on manually.
Is it possible to troubleshoot Night Light by resetting Windows settings?
Yes, resetting Windows settings can help resolve persistent issues with Night Light. If you’ve tried other troubleshooting steps without success, resetting might bring the feature back to functionality. To do this, go to Settings > Update & Security > Recovery, and choose “Reset this PC.” This process allows you to keep your files while resetting settings to their default state.
Before resetting, ensure you’ve backed up any essential data, as some settings and installed applications may be lost during the reset. After the reset, check if the Night Light feature works as expected. If it does, you can slowly reintroduce your settings and applications one by one to identify any that may have been causing conflicts.
