Adjusting your screen brightness in Windows 10 is a simple way to reduce eye strain, save battery life, and customize your viewing experience. Whether you’re in a bright room or dark environment, setting the right brightness level ensures comfort and optimal display quality. Before starting, make sure your device is powered on and your display drivers are up to date for the best performance. This guide walks you through easy, step-by-step methods to change your brightness on Windows 10, whether using the Settings app, Action Center, or keyboard shortcuts.
What You’ll Need
- A Windows 10 PC or laptop with a functioning display
- Optional: Keyboard with brightness adjustment keys (usually marked with sun icons)
- Optional: An active internet connection if updating drivers or accessing online settings
Step-by-Step
- Using the Action Center
– Click on the Action Center icon located at the bottom right corner of your taskbar (it looks like a speech bubble) or press Windows key + A.
– In the Action Center panel, look for the brightness slider. If it’s visible, drag the slider left to decrease brightness or right to increase it.
– Adjust until you reach your preferred brightness level. - Via Windows Settings
– Click on the Start menu and select the gear icon to open Settings, or press Windows key + I.
– In Settings, click on ‘System’.
– From the left sidebar, choose ‘Display’.
– Under the ‘Brightness and color’ section, use the slider labeled ‘Change brightness’ to adjust the screen brightness. Drag it left for dimmer, right for brighter.
– If the slider is grayed out, your device may not support manual brightness adjustment through software, or you might need to update your display drivers. - Using Keyboard Brightness Keys
– Many laptops have dedicated brightness keys, often marked with sun icons or labeled as brightness up (+) and down (–).
– Press the appropriate key (often F1, F2, or a function key combined with the Fn key) to adjust brightness incrementally.
– Observe the screen as you press the keys to find your desired brightness level. - Through Device Manager (if other methods fail)
– Right-click the Start button and select ‘Device Manager’.
– Expand ‘Display adapters’.
– Right-click your display driver and select ‘Update driver’ to ensure you have the latest version.
– Sometimes, updating or reinstalling your display driver can resolve issues with adjusting brightness. - Using Power Options
– Open Control Panel (search for it in the Start menu).
– Navigate to ‘Hardware and Sound’ > ‘Power Options’.
– Click on ‘Change plan settings’ next to your selected power plan.
– Adjust the brightness slider for both ‘On battery’ and ‘Plugged in’ modes.
– Save your changes to apply the new settings.
Common Mistakes
- Trying to adjust brightness when the slider is grayed out—this often indicates driver issues or hardware limitations.
- Not updating display drivers, which can prevent brightness adjustments from working properly.
- Using external monitors that have their own brightness controls, which may override Windows settings.
- Ignoring power plan settings that can restrict brightness adjustments when on battery.
- Assuming brightness adjustment is only through Settings—many devices also support quick adjustments via keyboard or Action Center.
Tips
- Keep your display drivers updated for seamless brightness control and overall display performance.
- Use the keyboard brightness keys for quick changes without navigating through menus.
- Adjust brightness based on ambient lighting—brighter in daylight, dimmer in dark environments.
- Set different brightness levels for battery and plugged-in modes to optimize power consumption.
- Consider using adaptive brightness if available, which automatically adjusts brightness based on ambient light.
Troubleshooting
If you encounter issues changing brightness in Windows 10, try these solutions:
- Update Display Drivers: Outdated or corrupted drivers can prevent brightness adjustment. Visit your device manufacturer’s website or use Windows Update to find the latest drivers.
- Check Power Settings: Ensure that your power plan allows for brightness adjustments. Sometimes, power-saving modes restrict brightness changes. Adjust this in Power Options.
- Enable Adaptive Brightness: Go to Settings > System > Display > Brightness and check if ‘Change brightness automatically when lighting changes’ is enabled. If not, enable it to see if it helps.
- Restart Your Device: A simple reboot can resolve temporary glitches affecting brightness controls.
- Reset Display Settings: If all else fails, resetting display settings to default may fix the issue. This can be done via Settings or Device Manager.
- Check for Windows Updates: Ensure your system is fully updated, as updates often fix bugs related to hardware controls.
Frequently Asked Questions
1. Why can’t I adjust brightness on my Windows 10 laptop?

2. How do I enable adaptive brightness?
Go to Settings > System > Display > Brightness, then toggle on ‘Change brightness automatically when lighting changes’ if available. Some devices also have this setting in the Intel or AMD graphics control panels.
3. Can I adjust brightness using third-party apps?
Yes, there are third-party tools available that can help control brightness, especially if built-in options are not working. However, using Windows settings is recommended for compatibility and safety.
4. Is there a way to set different brightness levels for battery and plugged-in modes?
