Steps

Step 1: Check your keyboard

Some laptops have a function key that, when pressed in combination with another key, can adjust screen brightness. Look for a sun icon or the words “BRIGHT” or “DIM” on your keyboard’s function keys. Press the corresponding key while holding down the “Fn” key to change brightness.

Step 2: Check Settings

On Windows 10, click the Start menu and select “Settings”. Click on “System”, then “Display”. Scroll down and find the “Brightness and color” section. Use the toggle to adjust brightness. Or click on “Night light settings” to adjust the brightness of your Night Light.

Step 3: Using the battery icon

On most laptop models running Windows 10, you may simply click on the battery icon located on the taskbar. You can drag the brightness slider to adjust the brightness according to your liking.

Step 4: Using the Mobility Center

On some laptops, you can press the Windows key and “X” to open the Mobility Center. Here, you can adjust features like screen brightness, volume, and power options.

Step 5: Brightness shortcuts

Some laptops have dedicated brightness shortcuts on the keyboard. For example, holding down the “Fn” key and pressing “F5” several times may increase brightness, while pressing “F6” may decrease it.

Step 6: Use Third-party apps

There are several third-party apps available on the internet that can help you adjust the screen brightness and color temperature. Some of the popular apps include Dimmer, f.lux, and Redshift.

Step 7: Video card settings

Video card drivers installed on your computer may also offer brightness control. Right-click on the desktop, select “Video options”, and adjust the brightness slider as required.

Step 8: Using the control panel

Click on the Start menu and select “Control Panel”. Click on “Hardware and Sound”, then “Power Options”. You will now find options that let you set the brightness level for different power modes.

Step 9: Change Screen Brightness through Registry Editor

To adjust the brightness manually through Registry Editor, press the Windows key + R and type “regedit” in the Run dialog box that appears. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Brightness. Here, you can set the brightness level from 0 to 255.

Step 10: Update Display Driver

An outdated or corrupted display driver can also affect the brightness settings. To update the driver, right-click on the Start menu and select “Device Manager”. Expand the “Display Adapters” option, right-click on your graphics card, and select “Update Driver”.

Step 11: Reinstall Display Driver

If updating the display driver doesn’t work, try reinstalling it. To do this, right-click on the Start menu and select “Device Manager”. Expand the “Display Adapters” option, right-click on your graphics card, and select “Uninstall Device”. Restart the computer and let Windows automatically reinstall the driver.

Step 12: Contact Support

If none of the above steps work, visit the manufacturer’s website or contact technical support for further assistance.

Explanation

Now that we’ve outlined the twelve ways you can change the screen brightness on your Windows computer, let’s take a deeper look at some of the more complicated steps.

For example, adjusting brightness via the Registry Editor may seem daunting. Editing the registry can be tricky and if done incorrectly, it can cause serious issues with your system. Therefore, we recommend backing up your registry before proceeding.

Additionally, updating and reinstalling the display driver is a step that may require some technical knowledge. It is important to make sure you have the correct driver for your graphics card before beginning the update process.
