This is a little ridiculous. I’m trying to change my brightness, which used to be a press of Fn + F2 and now I have to go into settings restart my computer run as compatibility which doesn’t even show up for me. My eyes are hurting and I just want windows 8 back. Oh wait, that also used to be at the touch of a few buttons and it would take me back. Now I have to apparently have a recovery drive on a flash drive. Why do you make everything so hard for us? Why cant it be as easy as before? What is the purpose, even, of changing it to be more difficult. I’d like to say I’m quite adept with computers, but if you ask people to do these basic tasks when even I can’t I’m surprised you aren’t flooded with complaints.

How to adjust Screen Brightness in Windows 10?

Now and then, you may want to adjust the brightness of your screen. It is almost unavoidable. Doing so ensures your comfort when working on your computer. What’s more, it saves battery power, especially when you are on the go, and there is no place nearby to charge.

When in a heavily lit room or a park, it is easier to see what is on your screen by increasing the brightness. Turning it down, on the other hand, when you are in a dim room, is a good idea for your eyes. There will be no glare that can give you a headache. So, you focus and finish the task you have at hand or even have fun on your PC.

How to Set Up Brightness on Windows 10

In this post, we will discuss different ways to change screen brightness on your Windows 10 computer. Apart from doing it manually, you can change the settings to allow your OS to automatically make changes. The modifications can be based on your power plan, battery level, or the intensity of ambient light.

Setting screen brightness is a basic task that is easy to do. Here are the different methods you can use:

Let us now look at how to apply each of the above methods.

Option 1: Change Brightness Using the Ambient Light Sensor

Modern computers have an ambient light sensor, similar to what is obtainable on tablets and smartphones. The sensor enables your OS to automatically increase screen brightness when your computer is in a bright place or decrease it when you are in a dark space.

Such an adaptive brightness allows for convenience. So, you do not have to keep adjusting your settings every time you change location or at different times of the day.

If you are using Windows 10, here is how to enable the feature:

Using the Windows Settings App

Using Control Panel

Now you know how to enable adaptive brightness. However, if you do not like the way the OS increases or decreases your screen lighting even at times you would prefer it does not, then you can disable the function and use other methods as shown below to control your screen brightness.

Option 2: Manually Adjust Screen Brightness

You can adjust your screen brightness at any time you desire. You do not have to leave the task to be automatically controlled by your operating system.

Several ways are available to you:

Let us take a look.

Using the Keyboard Shortcut

So, what is the shortcut key to adjust brightness on Windows 10? It is the same on all laptops. A sun icon marks the brightness keys. They are among the function keys (That is, the F-keys, directly above the row of number keys).

Press the function keys that have the brightness icon to either increase or decrease the brightness of your screen. If pressing the keys alone does not work, you may have to hold the Fn key. The key is beside the Ctrl key at the bottom-left corner of your keyboard.

Using the Buttons on Your External Display

If your computer has an external display, you simply have to use the buttons on the device to adjust brightness. The buttons are usually near the power button on your monitor. On some monitors, you may have to press an Options or Menu button to reveal an on-screen menu that shows the brightness settings which you can then adjust.

Now, apart from pressing the brightness keys on your keyboard or using the buttons on your monitor, you can also control your computer’s backlight directly from your system interface. However, it is important to note that you cannot adjust brightness from the options in your OS if you are using an external monitor. Instead, you will have to use the buttons on the monitor, as already discussed above.

Let us now look at how to adjust brightness from the Windows options.

Via the Battery Icon

This method is the easiest method you can try. All you have to do is to right-click on the battery icon displayed in the right corner of your taskbar. Then, click on the brightness tile. Keep in mind that brightness will increase by 25% each time you click the tile.

Via the Action Center

The Action Center in Windows 10 not only puts app notifications in one place, but it also provides you with quick actions. You can go through there to adjust your screen brightness.

Click on the Action Center icon in the right corner of your taskbar. You can also press the Windows +A combination on your keyboard. Then, drag the slider to adjust the brightness of your screen.

Note: If you do not find brightness settings in the Action Center, here is what you have to do:

Via the Windows Mobility Center

You can as well change the brightness by using the Windows Mobility Center:

Via the Settings App

To manually adjust your screen brightness:

Note: If you cannot use the brightness slider, it either means that you have an external monitor or that your display driver is outdated. If the former is the case, then press the buttons on your monitor to control brightness. On the other hand, if you are not using an external monitor but still cannot access the brightness slider, then you have to update your display driver.

Don’t worry because the process of updating drivers on Windows is easy as long as you have a good Internet connection. The first option you have is to go through the Device Manager:

Resolve PC Issues with Driver Updater

Unstable PC performance is often caused by outdated or corrupt drivers. Auslogics Driver Updater diagnoses driver issues and lets you update old drivers all at once or one at a time to get your PC running smoother

Via Control Panel

Since Windows 7 and Windows 8 do not have the Settings app, you can make use of Control Panel instead:

Option 3: Change Brightness According to Battery Level

When your battery begins to run low, there is a feature in Windows 10 that enables you to conserve some power. This way, you can continue working on your PC for longer. Enabling the Battery Saver feature turns down your screen’s light when your battery is low. If this sounds like a good idea to you, here is how to activate it:

After you have completed the above steps, your backlight reduces automatically every time your battery falls to the percentage you have chosen. As it turns out, Microsoft is yet to provide an option that lets you set how dim your screen will go when Battery Saver kicks in.

Option 4: Change Brightness Based on Your Power Plan

It is possible to have different brightness levels depending on whether your computer is charging or running on battery. You can enjoy having a brighter screen when your computer is charging. On the other hand, when there is no power outlet nearby, you may want to have a dimmer display to save battery.

Windows will automatically adjust your brightness according to your power plan. Here is how to set it:

Note: Alternatively, you can open the Run dialog by pressing the Windows logo + R keyboard combination.

Conclusion

In this guide, we discussed different ways to adjust screen brightness on your Windows 10 computer. Modifying brightness is essential to your comfort and the health of your eyes.

There is one question that users often ask: “Why Can’t I Change My Brightness on Windows 10?” The solution to the issue lies in updating your graphics drivers. We recommend running a scan with Auslogics Driver Updater to install the correct drivers for your device.

We hope that this guide has been helpful to you. Feel free to leave us a comment in the section below. We will like to hear from you.

7 ways to adjust the screen brightness in Windows 10

If you spend a lot of time on your Windows 10 computer or device, knowing how to turn up the brightness and how to lower it can come in handy. This setting is especially important when you use a laptop or a tablet, because, whether you are indoors or outdoors, you might need to adjust the display’s brightness according to your surroundings. Luckily, Windows 10 offers several options for changing this setting. Read this tutorial and learn how to turn down the brightness or how to increase the brightness for your display in Windows 10:

NOTE: The features presented are available in Windows 10 November 2019 Update or newer. If you’re using an older version of Windows 10, you might not have access to all the features. Check your Windows 10 build and, if necessary, get the latest Windows 10 update available for you.

1. How to adjust the brightness in Windows 10 using keyboard shortcuts

On some keyboards, there are keys specially designed to help you modify the screen brightness with ease. On an HP Spectre 13t laptop, you can use the F2 and F3 keys to lower or increase the screen brightness.

On Surface Pro devices with type covers, you can use the keyboard shortcut Fn + DEL to increase the brightness and Fn + Backspace to decrease it.

On our Lenovo Legion Y520 laptop with Windows 10, you can press the key combination Fn + F11 to lower the brightness and Fn + F12 to increase it.

These keys and keyboard shortcuts are available on most Windows 10 laptops and tablets. Look for similar keys with the brightness-specific sun icon on them.

Sadly, you don’t get these keys on keyboards for desktop computers, since each monitor has its own settings for controlling brightness, as you can see in the next section.

2. How to adjust the brightness in Windows 10 using the physical buttons of your monitor

While some monitors have dedicated buttons for adjusting brightness (either in front or on one of their edges), for others, you have to look through their specific menus to find the brightness controls. Consult the manual for your display to navigate through its menus and find the appropriate setting.

3. How to adjust the brightness in Windows 10 using the Quick actions

The Quick actions in the Action Center can also be used to change the brightness. Use the keyboard shortcut Windows + A to open the Action Center, revealing a brightness slider at the bottom of the window.

Moving the slider at the bottom of the Action Center left or right changes the brightness of your display.

4. How to adjust the brightness in Windows 10 using the Settings app

You can also use the Settings app to change the brightness level. Open Settings by using the Windows + I keyboard shortcut, and click or tap on System.

The System category opens in the Display tab. Use the slider under “Brightness and color” to “Change brightness for the built-in display.“

You can also enable the “Change brightness automatically when lighting changes” option to have your device automatically change the brightness level based on how much light its sensors are measuring in your environment.

5. How to adjust the brightness in Windows 10 using the Windows Mobility Center

The Windows Mobility Center can also be used to modify the brightness of your display. Type mobility in your taskbar’s search field, and then click or tap on “Windows Mobility Center.“

Use the slider under Display brightness to adjust the brightness level.

6. How to adjust the brightness in Windows 10 using PowerShell

You can also use the almighty PowerShell to change the brightness of your display. Open PowerShell by typing “powershell” in the taskbar’s search field, and then clicking or tapping on Windows PowerShell.

To change the brightness, enter the following command:

Replace brightnesslevel with the percentage value you want for your display’s brightness, from 0 to 100. To set the brightness at 70%, we entered the command:

As soon as you press Enter, the brightness is adjusted according to your preferences.

7. How to adjust the brightness in Windows 10 by changing the Power mode

Lowering the screen’s brightness decreases energy consumption and increases the autonomy of your device. For laptops and tablets, Windows 10 has a setting that changes the brightness of your display according to the Power mode that you use. To enable this option, first click or tap on the Power icon in the system tray, on the right side of the taskbar, and then access Battery settings.

TIP: If you can’t see the Power icon on your device’s system tray, you can learn how to find it and show it, by reading: The Windows 10 system tray – How to show or hide icons!

In the Battery settings window, scroll down to the Battery saver section. Check the box at the bottom, next to the “Lower screen brightness while in battery saver” option.

This setting automatically dims the screen when your device is trying to save battery. Click or tap the Power icon in the system tray again, and move the Power mode slider all the way to the left for “Best battery life.“ As long as your device is not plugged in, this should lower the display brightness, thus saving battery.

What method do you prefer to change the brightness of your display?

Knowing how to increase and how to lower the brightness helps you be more productive and focused. A screen that is too bright or too dim can take its toll on your eyes and make you uncomfortable. Which method do you like best for changing the brightness of your display? Do you know of any others? Comment below and let’s discuss.
