How Can You Adjust Screen Brightness on Windows PCs?

Below, I’ve described seven different methods you can try to adjust screen brightness on Windows PCs. 

Use the Keyboard Keys

Using the keyboard’s keys is the fastest way to adjust screen brightness on Windows PCs. Note that it’s possible that you won’t have these keys because not all keyboards are created equal, but it’s still an option worth considering. The F1 through F12 keys are located at the top of your keyboard, and depending on your keyboard, two of these numbers will help you adjust your screen’s brightness easily. 


For example, some keyboards feature a brightness option where pressing F5 increases the brightness while pressing F4 decreases it. On mine, I have an F9 key that lowers brightness and an F10 key that increases it.

Use Windows 10/11 Settings

Another way to adjust screen brightness on Windows PCs is through Settings. Here’s how to do it:

  • To open Settings, press Windows key + I.
  • Click on System > Display.
  • You should notice a slider next to “Brightness and color” that you can use to adjust brightness as high or low as needed. You’ll see the brightness change in real-time, so just use the Brightness slider till you get the ideal level of brightness.

Use the Action Center

Here’s yet another quick and easy way to adjust screen brightness on Windows PCs — the Action Center! By clicking simultaneously on the Windows + A keys, you can access the Action Center. The first slider up will be the brightness slider. To change your screen’s brightness, use your fingers if your computer has a touchscreen or your mouse.

So far, this is the third suggestion to adjust screen brightness on Windows PCs, and I feel like you should have found one that works great for you by now. However, if you haven’t, keep reading.

Use the Mobility Center on Windows 11

If you still need more alternatives to adjust screen brightness on Windows PCs, you can also check out the Mobility Center. By right-clicking on the Start Menu and selecting Mobility Center at the top, you’ll get to the Mobility Center easily. The first choice on the left will be Display Brightness. Once you’re there, change the brightness with the slider until it suits your preferences.


Use Command Prompt

Even if this method is less intuitive than the others in this guide, it may be all that works for you to adjust screen brightness on Windows PCs. You’ll need to launch the Command Prompt as an Administrator if you must use it to change your screen’s brightness.

To do this, enter Command Prompt in the search bar and select Run as administrator from the list of results that appear. Enter the following command once it is open:

PowerShell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1, BrightnessValue)


Don’t forget to modify the brightness value where it reads so in the command prompt. Here’s what I mean —, the command should be as follows if you want to set your screen’s brightness to 70:

PowerShell (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods).WmiSetBrightness(1, 70)

Use Battery Saver

Usually, when my laptop’s battery is running low during a power outage, I make some adjustments to extend its battery life. One of them is turning on battery saver mode, and this effects changes like modifying the screen brightness to conserve battery. You can use this as a way to adjust screen brightness on Windows PCs.

Here’s what you need to do:

  • Go to Settings > System > Power and Battery > Battery Saver
  • Next, set the percentage for when you’d like the Battery Saver mode to kick in to start by selecting the option that reads “Lower screen brightness when using Battery Saver”.

Use Adaptive Brightness in Windows 10/11

It’s ideal for your screen’s brightness to match the ambient lighting so you can prevent eye strain and excessive battery consumption. Setting the brightness to adjust automatically based on the ambient light makes sense in this case, and it’s one way to adjust screen brightness on Windows PCs.


Having a brightness sensor on your smartphone is required for this feature to work. Here’s how to enable it:

  • To open Settings, press Windows key + I.
  • Activate System > Display. Select Brightness in Windows 11.
  • Click the option to “Change brightness automatically when lighting changes” if you see it. You’ll know that your PC does not have this sensor if you are unable to see the option.
