Adjusting your screen brightness on Windows 11 is essential for enhancing your viewing experience, reducing eye strain, and conserving battery life. Whether you're working in bright sunlight or a dim environment, Windows 11 provides several methods to fine-tune your display brightness to suit your needs. This guide will walk you through various ways to change your screen brightness effectively.
Use dedicated keyboard keys
One of the simplest ways to adjust your screen brightness is by using the dedicated keys on your keyboard. Most modern laptops feature brightness control keys, often identified by sun icons, located on the function keys (F1 to F12) or sometimes on the arrow keys.
Step 1: Locate the brightness keys on your keyboard. Look for keys with sun symbols—typically, one for increasing and one for decreasing brightness.
Step 2: Press the brightness keys to adjust the brightness level. On some laptops, you may need to hold down the Fn key while pressing the brightness keys. For example, pressing Fn + F7 or Fn + F8 to decrease or increase brightness, respectively.
Adjust brightness using Quick Settings
Another quick method to modify your screen brightness is through the Quick Settings panel in Windows 11.
Step 1: Click on the network, volume, or battery icon at the far right of the taskbar to open the Quick Settings panel.
Step 2: Find the brightness slider, indicated by a sun icon.
Step 3: Drag the slider left to reduce brightness or right to increase it until you reach your desired level.
Adjust brightness via Windows Settings
You can also change the screen brightness through the Windows Settings app for more precise control.
Step 1: Open the Settings app by pressing Windows + I on your keyboard.
Step 2: In the Settings window, select System from the left sidebar.
Step 3: Click on Display on the right pane.
Step 4: Under the "Brightness & color" section, use the brightness slider to adjust the screen brightness to your preference.
Troubleshooting missing or non-functional brightness slider
If you're unable to adjust your screen brightness because the brightness slider is absent or not functioning correctly, you may need to update or reinstall your display drivers.
Step 1: Right-click on the Start button and select Device Manager from the context menu.
Step 2: In the Device Manager window, expand the Display adapters category.
Step 3: Right-click on your display adapter (e.g., Intel UHD Graphics, NVIDIA, AMD) and select Uninstall device.
Step 4: Confirm the uninstallation if prompted.
Step 5: Restart your computer. Windows 11 will attempt to reinstall the display driver automatically.
Step 6: If the issue persists, go back to Device Manager, right-click on the display adapter, and choose Update driver, then select Search automatically for drivers.
Automatically adjust brightness based on power mode
To conserve battery life on laptops and tablets, Windows 11 offers an option to reduce screen brightness automatically when battery saver mode is enabled.
Step 1: Right-click on the battery icon in the system tray and select Battery saver settings.
Alternatively, navigate to Settings → System → Power & battery.
Step 2: In the Power & battery settings, expand the Battery saver section.
Step 3: Toggle on Lower screen brightness when using battery saver. Now, whenever battery saver mode is active, your screen brightness will automatically reduce to save power.
Step 4: To enable battery saver mode immediately, click on the Turn on now button next to Battery saver in the settings.
You can also enable battery saver mode from the Quick Settings panel by clicking on the battery saver icon.
Step 5: To set battery saver mode to activate automatically at a certain battery level, choose the desired percentage from the dropdown menu under Turn battery saver on automatically at.
Note that battery saver mode can only be enabled when your device is not plugged into a power source.
Enable Night Light to reduce eye strain
Staring at a bright screen for extended periods, especially at night, can lead to eye discomfort and disrupt your sleep patterns. Windows 11's Night Light feature reduces the blue light emitted from your screen, displaying warmer colors to ease eye strain.
Step 1: Open the Display settings by going to Settings → System → Display. Then, toggle on Night light under the brightness slider.
Step 2: To customize the Night Light settings, click on the Night light option (do not click the toggle itself).
Step 3: Adjust the Strength slider to set the intensity of the warmer colors to your preference.
Step 4: To schedule Night Light, toggle on Schedule night light. You can then choose to have it turn on from sunset to sunrise or set specific times.
Adjust brightness on external monitors
If you're using an external monitor, adjusting brightness may vary depending on the manufacturer. Many monitors come with their own On-Screen Display (OSD) controls or software that allow you to modify settings like brightness, contrast, and color.
Check for physical buttons on your monitor, usually located on the side or bottom edge, to access the OSD menu and adjust brightness settings. Alternatively, some manufacturers provide software utilities to control display settings from your computer.
Change brightness using graphics card software
If you have a dedicated graphics card or integrated graphics, you can adjust display settings through the graphics control panel provided by the manufacturer (e.g., NVIDIA, AMD, or Intel).
Step 1: Access your graphics control panel by right-clicking on the desktop and selecting the relevant option. For example, choose NVIDIA Control Panel, AMD Radeon Settings, or Intel Graphics Settings.
For NVIDIA graphics drivers
Step 1: Open the NVIDIA Control Panel.
Step 2: In the left pane, under Display, select Adjust desktop color settings.
Step 3: Choose the display you want to adjust if you have multiple monitors.
Step 4: Use the Brightness slider to set your desired brightness level, then click Apply.
For AMD graphics drivers
Step 1: Open the AMD Radeon Settings or Catalyst Control Center.
Step 2: Navigate to Desktop Management and select Desktop Color.
Step 3: Choose your display if you have multiple monitors.
Step 4: Adjust the Brightness slider to your preference.
For Intel integrated graphics
Step 1: Open the Intel Graphics Control Panel by right-clicking on the desktop and selecting Intel Graphics Settings or Graphics Properties....
Step 2: In the control panel, select Color Settings from the left sidebar.
Step 3: Adjust the Brightness slider to modify your screen brightness.
Note that the options and interface might vary depending on the graphics driver version.
Control brightness using PowerShell
For advanced users, you can adjust screen brightness using Windows PowerShell.
Step 1: Open Windows PowerShell by searching for PowerShell in the Start menu and selecting it.
Step 2: To set the brightness level, type the following command and press Enter:
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,"Brightness Level")Replace "Brightness Level" with a value between 0 and 100 representing the desired brightness percentage.
For example, to set the brightness to 50%:
(Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1,50)
Your screen brightness will adjust immediately upon running the command.
