How to Adjust Your PC’s Screen Brightness, Manually and Automatically
Photograph by Leigh Prather/Shutterstock.com You will most likely need to adjust the brightness of your screen on a frequent basis. Turning up the brightness while it’s bright outdoors can allow you to see better. While in a dark environment, you’ll want the lighting to be dim so that it doesn’t strain your eyes. Reduce the brightness of your laptop’s screen to save energy and extend the battery life of your laptop. Aside from manually increasing the screen brightness, you may have Windows change it for you in a variety of ways, depending on your preferences.
How to Adjust Brightness Manually on a Laptop or Tablet
There are shortcut buttons for increasing and decreasing your laptop’s brightness that are found on most laptop keyboards. These keys are frequently found as part of the row of F-keys (that is, the keys F1 through F12) that appear above the number row on your keyboard. The brightness of the screen may be adjusted by looking for a symbol that corresponds to it–often a sun emblem or something similar–and pressing the appropriate keys. If you’re pressing a function key, you may need to press and hold the Fn key on your keyboard, which is usually placed towards the bottom-left corner of your keyboard, while you hit the other keys.
You may also change the brightness of the display from inside Windows itself.
- Windows 10 has a fast brightness slider, which can be found in the Action Center.
- If you are unable to see the slider, select “Expand” from the drop-down menu above the tile grid.
- On a touchscreen, you may also launch the Action Center by swiping in from the right side of the screen, as seen below.
- Open the Settings app from your Start menu or Start screen, pick “System,” and then click “Display” to customize your display.
- If you’re using Windows 7 or 8, and you don’t have a Settings app, you may access this feature through the Control Panel.
- Additionally, you’ll find this option in the Windows Mobility Center.
To access it, right-click on the Start button on Windows 10 and 8.1 and select “Mobility Center,” or hit Windows key + X on Windows 7, will bring up the Mobility Center. In the popup that displays, adjust the “Display brightness” slider to your liking.
How to Adjust Brightness Manually on an External Display
The majority of the approaches described in this article are intended for use with laptops, tablets, and all-in-one computers. If, on the other hand, you’re using a desktop PC with an external display–or even attaching an external display to a laptop or tablet–you’ll need to alter this option on the external display itself, and you won’t be able to do it automatically in most instances. Look for “brightness” buttons on the display, and use them to alter the brightness of the screen’s illumination.
On a computer display, these buttons are frequently found near the power button, which makes sense.
How to Automatically Adjust Brightness When You’re Plugged In
If you’re using Windows, should you run it with the Balanced, Power Saver, or High Performance Power Plans set to high performance or low performance? It is possible to configure different display brightness levels on your laptop or tablet depending on whether or not you are hooked into an electrical outlet. As an example, you might adjust the brightness of your computer to a high level while it’s plugged in and a lesser one when it’s running on battery power. The brightness of your screen would then be automatically adjusted by Windows.
Select “Hardware and Sound,” then “Power Options.” Next to the power plan you’re currently using, click the “Change plan options” link next to it.
Under “Adjust plan brightness,” you may set different screen brightness settings for when you’re “on battery” and when you’re “plugged in.” This parameter is connected to the power plan that you have selected.
How to Automatically Adjust Brightness Based on Remaining Battery Life
Depending on how much battery life is left in your laptop or tablet, you may also set your display’s lighting to automatically adjust itself. This may be accomplished through the use of the Battery Saver option in Windows 10. Start by opening the Settings app, going to “System,” and then selecting “Battery.” Double-check that the “Lower screen brightness when in power saving” option is selected, and then select the percentage at which you’d like Battery Saver to be activated. When Battery Saver is activated at that level, it will dim your backlight, allowing you to save on electricity costs.
We regret that there is currently no way to customize the precise brightness level that Battery Saver will select. You may also manually enable this option from the battery icon on your device’s home screen.
How to Automatically Adjust Brightness Based on Ambient Light
Depending on how much battery life your laptop or tablet has remaining, you may also set your display’s lighting to automatically change as needed. The Battery Saver function in Windows 10 may be used to do this task. Start by opening the Settings app and selecting “System,” followed by “Battery.” Double-check that the “Lower screen brightness when in power saving” option is turned on, and then select the percentage at which you’d want Battery Saver to kick in. When Battery Saver is activated at that level, it will dim your backlight, allowing you to save on energy costs.
We regret that there isn’t a method to control the precise brightness level that Battery Saver selects.
9 Ways to Adjust Screen Brightness on Your Windows 10 PC
Making changes to the display settings on a new computer is a simple process. It’s critical to understand how to change the brightness on Windows 10 because if you’re experiencing eye strain or headaches, it’s possible that the display brightness is to blame. Fortunately, you have the option of manually or automatically adjusting the brightness based on factors like as battery life or ambient light. We’ll teach you how to adjust the screen brightness on Windows 10, whether you want to minimize or enhance the amount of light coming in.

Can’t adjust brightness on Windows 10? Here’s how to fix it
Changing the brightness of our smartphones has become a routine operation that we conduct on a daily basis. The brightness of the screen may be increased to make it easier to see what is on the screen throughout the day. In the same way, you may reduce it at night to give your eyes a chance to rest. A bug in Windows 10 prevents you from adjusting the brightness of your screen at all, due to an issue in the operating system. The fact that you have to fiddle with the settings on a daily basis might rapidly become irritating.
Why is this an Issue?
While PC users may only perceive this as a minor inconvenience, laptop users have experienced significant battery concerns. We are all aware that lowering the brightness of your display is one of the most effective techniques to extend the life of your battery. This can be attributed to the brightness being set too high, which results in a quick drain of batteries.
On a computer, you are almost certainly given the option of adjusting the brightness of your monitor. If, on the other hand, Windows 10 does not allow you to adjust the brightness on a laptop, you should investigate the problem immediately.
Fixed: can’t adjust brightness on Windows 10
There are several excellent solutions for resolving problems with the brightness of your computer display that we’ve gathered below. Some answers are only applicable to specific devices, so double-check that you’re reading the correct area!
Update your Display Adapter Drivers
No matter what device you’re using, the first thing you should do is update your driver software to the latest version. Many Windows 10 customers have claimed that doing so has resolved their difficulties with the brightness not adjusting properly. When it comes to updating your drivers, there are several options available. Choose one of the guides that best suits your style and approach.
Update your Drivers Manually
- In order to start theRunapplication, press the Windows and R keys at the same time. Type indxdiag and hit the Enter key
- Select the Display tab from the drop-down menu. Read the name and manufacturer of your card under the heading “Device.”
- Navigate to the manufacturer’s website and click on the “Downloads” link to begin the process. Some of the most popular manufacturer pages are as follows:

- NVIDIA Driver download page
- AMD Drivers and support page
- Intel Drivers and Software page
- Locate and download the appropriate driver for your graphics card. The driver may be installed by double-clicking the downloaded file and then following the on-screen instructions.
Make certain that you are constantly obtaining and installing the most recent version of the driver that corresponds to your graphics card. Alternatively, you may conduct a search on Google or contact the customer service department of your manufacturer if you are still unclear. Never download drivers from a third-party website because these files may include harmful code and might cause damage to your system. Always double-check that the URL address of the website from which you’re downloading is the same as the one for the official website.
Update your Driver automatically
There are a variety of approaches that may be used for automatic driver upgrades. In this case, we will be utilizing the integrated Device Manager.
- Hit and hold theWindowskey for a few seconds, then press R. In this case, theRunapplication will be launched. To launch the Device Manager, start by typing indevmgmt.msc and pressing Enter. By clicking on the arrow icon, you may expand the Display adaptors section. Update your driver by selecting it from the context menu of your computer’s mouse.
Driver Booster, DriverHubor, and DriverPack Solution are examples of third-party updater software that may be found and downloaded from the Internet. Although these three programs are all free and simple to use, you can always explore around the web for more complicated applications.
Adjust the brightness from Power Options
If you are unable to adjust the brightness of your screen, there is a possibility that you are experiencing a Windows 10 issue. By adjusting your Power settings, you may get rid of this problem. This approach works on laptops, but it may also be used on computers running Windows 7 or Windows 8:
- Control Panelcan be found by searching for it in yourSearchbar. Open the first result that comes up. Change the view mode to Category, then select Hardware and Sound from the drop-down menu. Select Power Options from the drop-down menu. On a laptop, you can right-click the Power icon in your taskbar and select Power Options
- On a desktop computer, you can right-click the Power icon in your taskbar and select Power Options
- Select your preferred plan and then click on theChange plan settingslink next to it. Rather of making any changes, select the Changeadvanced power settingslink instead. You’ll discover it at the bottom of the window, if you look closely. Continue to scroll down till you seeDisplay on the screen. By selecting the gear icon, you may make it larger. To view all of the following choices in further detail, click on the icon next to each of them:
- The following options are available: increased display brightness, decreased display brightness, and adaptive brightness.
- Make your modifications and then click theApplybutton. By hitting the OK button, you may close this window. Your PC or laptop should be restarted.
Re-enable your PnP Monitor
This strategy is effective for users of the PnP monitor. PnP stands for “plug and play,” and it refers to the ability to use your device without the need to install any drivers. The actual problem is that some driver or system upgrades may cause your display to be unresponsive in the Device Manager. Although the exact reason of this is unknown, it is a good idea to check to see if it has occurred to you. When utilizing a generic PnP monitor, you may be able to resolve the brightness difficulties that Windows 10 is experiencing by following the procedures listed below:
- Hit and hold theWindowskey for a few seconds, then press R. In this case, theRunapplication will be launched. To launch the Device Manager, start by typing indevmgmt.msc and pressing Enter. By clicking on the arrowicon, you can see the monitors. Enable the device by selecting it from the context menu of your PnP monitor. If the problem persists, restart your computer and try changing the brightness again.
Are you still having trouble? Make sure to read the next part as well, since it has an alternative option.
The PnP Monitors are the only ones that will function with this strategy, just as the previous one. If you’re using one of these devices, take the steps below to see if they help to resolve your brightness problems:
- Hit and hold theWindowskey for a few seconds, then press R. In this case, theRunapplication will be launched. To launch the Device Manager, start by typing indevmgmt.msc and pressing Enter. From the Device Manager’s menu, select View, then Show hidden devices from the drop-down list. If you already have this turned on, leave it turned on. Monitors may be accessed by clicking on the arrow symbol. Select the Uninstall device option from the context menu of each hidden device. As seen in the illustration, hidden gadgets seem more transparent than conventional devices. If the problem persists, restart your computer and try changing the brightness again.
Fix an ATI bug via registry Editor
A issue in Catalyst has been reported by certain ATI graphics card users, who claim that the software is unable to regulate the brightness of their displays. The Catalyst version 15.7.1 is the one that has received the most reports of this problem.
However, this does not rule out the possibility that the problem would reappear in future editions. You’re an ATI user who also has Catalyst installed on your computer? If you are unable to alter your brightness, the following procedure may be able to assist you:
- Hit and hold theWindowskey for a few seconds, then press R. In this case, theRunapplication will be launched. To open the Registry Editor, type inRegEdit and press Enter. You will be prompted to launch the Registry Editor
- While in the Registry Editor, you can browse by clicking on the arrow icon next to the name of the folder you want to edit. This will allow you to browse to the following path: control class 0000 is located in the HKEY LOCAL MACHINE directory under the SYSTEM subdirectory. Double-click on MD EnableBrightnesslf2 to make it active. ChangeValueto0 and then do the same thing withKMD EnableBrightnessInterface2 to complete the process. Following that, we’ll take a detour to a different route: HKLM:SYSTEM: CurrentControlSet:Control:Class:0001
- Double click onMD EnableBrightnesslf2and set itsValue to 0. HKEY LOCAL MACHINE: SYSTEM: CurrentControlSet:Control:Class:0001
- Double click onMD EnableBrightnesslf2and change itsValue to 0. Replace KMD EnableBrightnessInterface2 with the same value
- Close the Registry Editor and restart your computer.

Fix: Windows 10 Brightness Won’t Change
Some customers have reported that they are unable to change the screen brightness on Windows 10 after installing an update or upgrading from an older Windows version. The majority of customers have reported that the screen brightness appears to constantly be set to the maximum setting, regardless of the power plan selected. Although this issue may not have a significant impact on the functionality of a PC (since the brightness can also be adjusted from the monitor), laptop users have reported that the fact that their machine is constantly running at maximum brightness has a negative impact on the battery life of their machine.
We have been successful in identifying a number of potential remedies that have shown to be useful for other customers who have encountered the same problem.
Method 1: Adjusting the brightness from Power Options
The majority of the time, the problem is caused by a classic example of a brightness settings bug, which can be remedied by adjusting basic power choices. Despite the fact that this flaw has existed since Windows 7, Microsoft has refused to resolve it as of now. For the sake of completeness, this exact solution may be used to resolve the brightness issue in both Windows 7 and Windows 8. Here’s a fast approach to resolving the brightness issue using the Power Options menu on your computer:
- To launch a Run box, press the Windows key + R at the same time. To access the Power Options menu, start by typing ” powercfg.cpl ” and pressing Enter. SelectChange plan settings from thePower Optionsmenu, followed by Change advanced power settings from the same menu. In the next window, scroll down to the Displaysection and click on the “+” icon to expand the drop-down menu that appears there. Afterwards, open the Display brightness option and manually change the parameters to your preference
- Step 3 should be repeated with the display brightness set to a lower value. Once this is done, ensure sure the Enable adaptive brightness option is turned off. Once all of your preferences have been established, press theApplybutton, and the screen brightness should be changed to the levels that you previously specified.
If, for any reason, this approach did not work or was not relevant, proceed to Method 2 further down.
Another typical solution for the brightness issue is to alter the brightness using theGraphics Propertiesmenu on the computer’s display. Keep in mind that this menu is controlled by your graphics card driver, and the appearance of the menu may vary depending on the version of the driver you are using. Using the Graphics propertiesmenu, here’s a fast approach to altering the brightness of your screen: Please keep in mind that the following actions were completed using the Intel Graphics and Media Control Panel.
- Graphics Properties may be accessed by right-clicking anywhere on your desktop and selecting it. Then selectAdvanced Modefrom the drop-down menu and press theOkbutton. Then, open the Display menu and selectColor Enhancement from the drop-down list. To change the brightness, utilize theBrightnessslider on the right-hand side of the screen until you’re pleased with the outcome
- When you’re finished, clickApply to save your new brightness setting.
If this procedure does not prove to be beneficial, go to Method 3.
Method 3: Updating the GPU drivers
If the previous two procedures have failed to yield a result, the actions that follow may just be the ticket. Some users have stated that they were able to determine that the problem was caused by their graphics card drivers.
The majority of them were able to permanently address the issue by deleting their GPU drivers. For a step-by-step walkthrough on how to update your GPU drivers in order to remedy the brightness issue on Windows 10, see the section below.
- To open the Run command, hold down the Windows key and the R key at the same time. To launch the Device Manager, start by typing “devmgmt.msc” and pressing Enter. Expand the drop-down menu associated withDisplay adapters in Device Manager, right-click on your GPU, and select Update Driver from the context menu (Update Driver Software). If you’re experiencing this issue on a laptop, keep in mind that the GPUs listed under Display Adapters are likely to be two separate GPUs from one another. Assuming this is the case, right-click on the integrated graphics (in my instance, it’s Intel(R) HD Graphics 3000)
- Then choose Properties. In the following box, choose Search automatically for updated driver software and wait to see if the process is successful in locating a newer version of the driver software. If it does, simply follow the on-screen instructions to complete the installation. The next step is intended to leverage your Internet connection in order to get the most recent driver available. Please keep this in mind: In order to succeed, you must have a reliable internet connection. In the event that Windows is successful in locating, downloading, and installing a new driver version for your integrated GPU card, reboot your computer and check to see whether you are able to change the brightness. If the driver search reveals that you already have the most recent driver installed or that the new driver is causing the same behavior as the old driver, go to the next step in the procedure. Return to the Device Manager main page, right-click on your integrated GPU driver, and choose Update drive (Update Driver Software) once more
- Selecting B rowse my computer for driver software instead of the first choice will result in the following results: On the following window, choose Allow me to choose from a list of available drivers on my computer from the drop-down menu. After that, selectMicrosoft Basic Display Adapter from the drop-down menu next toShow suitable hardware and press theNextbutton. Restart your computer once again after the Basic Display Adapter driver has been successfully installed. It is likely that your problem will be addressed after your computer has restarted.
Proceed to Method 4 if you are still having problems.
Method 4: Re-enabling Generic PnP Monitor
According to several customers, there appears to be a Windows 10 particular problem that happens occasionally soon after the graphics driver is installed automatically – either during the upgrading of the CPU via Device Manager or directly after the graphics driver is updated automatically. However, it has been discovered that something may go wrong and cause the Generic PnP Monitor to be disabled (preventing the user from being able to alter the screen brightness). The problem will be resolved as soon as the Generic PnP Monitor is enabled again, if this is the source of the problem.
- To open a Run window, hold down the Windows key and the R key at the same time. To launch the Device Manager, start by typing “devmgmt.msc” and pressing Enter. Expand the Monitors drop-down menu in Device Manager, right-click on the PnP Monitor, and select Enable Device from the context menu. Whether the problem persists, reboot your system to see if the problem has been repaired and you are able to change the screen brightness once more.
If you’re still having trouble with the problem, go to the next step.
Method 5: Updating the dedicated GPU driver
Please go to Method 2 if you are still having trouble with this issue.
- Visit the download page for your GPU manufacturer and download the most recent driver version that corresponds to your GPU model and Windows operating system version. Use this URL (here) for ATI graphics cards and this link (here) for Nvidia graphics cards. Open the driver installer and follow the on-screen directions to update your driver, after which you should reboot your machine. Once your computer has been restarted, check to see whether the Generic PnP Monitor was accidentally turned off during the installation process. To do so, open a Run box (Windows key + R), type “devmgmt.msc,” and then press Enter to launch the Device Manager application. Afterwards, expand the drop-down option ofMonitorsand ensure Generic PnP Monitoris selected from the list. If it isn’t, right-click on it and select Enable device from the context menu. Before concluding, experiment with different screen brightness settings to determine whether this strategy was effective. If it continues to fail, go to the technique listed below.
Method 6: Changing the Display type to Discrete in Bios (Lenovo)
If you’ve exhausted all of the options listed above without success, it’s possible that your problem is related to a BIOS setting. Take note that this problem has only been observed on Lenovo computers, according to reports (particularly on Lenovo Thinkpad T400 and older models using the same BIOS versions). It is necessary to access your BIOS (by pressingF2during the first boot process), navigate to theConfigurationtab, and change theGraphics Devicetype fromSwitchable Graphics toDiscrete Graphic in order to resolve this manufacturer-specific issue.
If this approach did not work or was not appropriate in your situation, proceed to the last procedure listed below.
Method 7: Fixing Catalyst bug via Registry Editor (ATI GPUs)
As several users have pointed out, the screen brightness issue might possibly be caused by a known Catalyst defect, which could be the cause of the problem (particularly with version 15.7.1). When this error occurs, users will be unable to alter the brightness of their screens or computers. In case you’re using an ATI graphics card and you already have Catalyst installed, try the steps below to see if they help to address your problem:
- To open a run command, press the Windows key + R at the same time. To launch the Registry Editor, type ” regedit ” and press Enter. Go to this key in the Registry Editor by clicking it twice: control class 0000 is located in the HKEY LOCAL MACHINE directory under the SYSTEM subdirectory. Make a double-click on MD EnableBrightnesslf2 and change theValue to 0. Continue using KMD EnableBrightnessInterface2 by following the same steps as before. Navigate to the following key to continue. HKEY LOCAL MACHINE SYSTEM CurrentControlSet Control Class 0001
- HKEY LOCAL MACHINE SYSTEM CurrentControlSet Control Class 0001
- Again, double-click MD EnableBrightnesslf2 andKMD EnableBrightnessInterface2 to set their values to 0
- Then close and restart your computer to complete the process. It should be addressed and you should be able to change the screen brightness when the next restart is completed.
