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
IN CONNECTION WITH: Disable Adaptive Brightness in Windows to Solve Dark Screen Issues Modern laptops and tablets are equipped with an ambient brightness sensor, which operates in a similar way to the sensor found on smartphones and tablets. Windows may make use of the sensor to provide “adaptive brightness,” which means that it will automatically increase your display brightness when you are in a bright location and decrease your display brightness when you are in a dark place. Although this is handy, some people believe that it is also a hindrance to their progress.
It’s possible that you’ll want to test it on and off to see which you prefer.
This option will only be available if your device is equipped with an ambient brightness sensor.
Open the Control Panel, select “Hardware and sound,” then “Power Options.” Next to the power plan you’re currently using, click “Change plan settings,” then “Change advanced power settings.” The “Display” section should be expanded at this point, followed by the “Enable adaptive brightness” section.
Consider the following scenario: you could disable it while plugged in and leave it on when operating solely on battery power.
Enabling automatic brightness will not prohibit you from manually adjusting your brightness using hotkeys or the controls in Windows whenever you like, so there is nothing to lose by experimenting with all of the choices listed above.
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.
1. Change Brightness in Windows 10 in Settings
The Settings application provides a simple method to modify the brightness of your Windows 10 computer. To accomplish this, follow these steps:
- To launch the Settings menu, press Win + It. Navigate to SystemDisplay
- Use theChange brightnessslider, which is located beneathBrightness and color. The light will be darker to the left and brighter to the right
If the slider is not available, it is most likely due to one of two reasons: If you’re using an external display, you may adjust the brightness by pressing the buttons on that monitor.
If this is the case, you will need to upgrade the display driver.
2. Change the Brightness on the Monitor
While utilizing a portable device (for example, a laptop), you may not be able to modify the brightness of your computer screen in Windows 10. This is due to the fact that the brightness is controlled by your external monitor. If this is the case for you, consult the paperwork that came with your monitor for advice on how to change the brightness because the precise instructions will differ from monitor to monitor. It is recommended that you have buttons on your monitor that activate an on-screen display, which you can then go through to adjust the brightness.
3. Change the Brightness in the Windows Mobility Center
The Windows Mobility Center also allows you to manually control the brightness of your screen. To get to this, hit the Windows key + X and then choose Mobility Center. The brightness of the screen may be adjusted using theDisplay brightnessslider, which is located here.
4. Adjust the Brightness in the Display Driver Control Panel
Your display driver maker will have its own control panel, through which you will be able to adjust the brightness of your display. For example, the Intel Graphics Control Panel and the NVIDIA Control Panel are two different types of control panels. That will be determined by your graphics card and which one you will utilize or own. If you have the Intel Graphics Control Panel, you may do the following:
- To change the display’s color settings, clickColor Settings, then adjust the Brightness slider before clickingApply.
Alternatively, if you have the NVIDIA Control Panel, you may do the following:
- Expand the Display option in the left-hand window. Adjust the desktop color settings by clicking on the corresponding button. UnderChoose how color is chosen, selectUse NVIDIA settings from the drop-down menu. Make adjustments to theBrightnessslider
5. Automatically Adjust Brightness for Battery Life
Lowering the brightness of your screen might help you get more life out of the battery of your portable device. Windows 10 has a battery-saving function that restricts alerts and background activities, and it may also automatically reduce your screen brightness if necessary. This is made possible by the following:
- To access Settings, press the Windows key + I and choose SystemBattery. Make sure that theTurn battery saver on automatically atdropdown is set to the desired number beneathBattery saver. Lower the screen brightness while the power saver is on. Because of this, it is not feasible to control the brightness level that is utilized.
Also from this page, you may manually turn on the battery saver at any moment by turning theBattery savertoggleOn.
6. Use Adaptive Brightness in Windows 10
Ideally, the brightness of your display should match the brightness of the surrounding environment, since this lowers eye strain and excessive battery consumption. One approach to assist with this is to have the brightness automatically adjust based on the amount of ambient light in your environment. It is only possible to use this function if your smartphone is equipped with a brightness sensor. To make it possible, you must do the following:
- To enter the Settings menu, press Win + I
- Then select SystemDisplay. Make sure you can see it and that it is set to “Change brightness automatically when lighting changes.” If you are unable to view this, you do not own the sensor.
7. Adjust the Brightness On a PC Using the Keyboard
It’s possible that your computer keyboard has shortcuts for increasing and decreasing the brightness. If you’re using a laptop, there’s a good chance that will happen. Keep an eye on the function keys; brightness is frequently indicated by a sun icon on them. The precise key combination will vary depending on the type of your keyboard. For example, you may be required to hold down or activate the Fnkey while concurrently pressing the relevant function key to complete the operation.
8. Brightness Adjustment Shortcuts in Windows 10
If you want to alter the brightness of your screen on Windows 10 without having to navigate through menu panels, there are two simple shortcuts you may use.
Adjusting the Brightness in the Action Center
You can rapidly adjust the brightness by clicking on the Action Center icon on the taskbar (or by pressing Win + A on your keyboard.) Then, using the brightness slider, adjust the brightness to your liking.
The brightness of the screen increases when the slider is moved to the right. If you don’t see the brightness slider, try these steps:
- To launch the Settings menu, press Win + It. Navigate to the SystemNotificationsactions folder. Make changes to your fast actions. When you click on this, the Action Center will be shown. ClickAddBrightnessDone

If you want it to be available at all times, right-click the icon and selectRun At Startup from the context menu.
9. Change the Brightness in Command Prompt
You may adjust the brightness of your screen using the Command Prompt if you so want. You should utilize the other techniques described here if they are not accessible for whatever reason. However, you can use this if they are not available. Perform a system search for cmd to locate and launch the Command Prompt. Then enter the following information: (Get-WmiObject -Namespace root/WMI -Class WmiMonitorBrightnessMethods) is a powershell command.

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:
- Page dedicated to Intel Drivers and Software
- Download website for NVIDIA drivers
- AMD Drivers and Support page
- AMD Drivers and Support 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.

- 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

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. In thePower Optionsmenu, click onChange plan options, then click onChange advanced power settings
- 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
If the problem persists, proceed to Method 4.
- 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
After attempting all of the ways listed above and failing miserably, you should concentrate your efforts on your dedicated graphics card (if you have one). Alternatively, it’s likely that your dedicated GPU is set up to handle graphics operations while your PC is not doing taxing tasks on the system. However, even though the idle mode is generally handled by the integrated GPU solution, a user modification or specific program installs may have prompted the dedicated GPU to take over the idle mode handling responsibility.
Listed below is a fast walkthrough of the entire process:
- 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.
Run a command by pressing the Windows key + R. Regedit may be accessed by typing the word regedit and pressing the Enter key. Navigate to the following key in the Registry Editor. control class 0000 is located in the HKEY LOCAL MACHINESYSTEM folder. Then double click on MD EnableBrightnesslf2 and change theValue to 0. Continue using KMD EnableBrightnessInterface2 and follow the same steps as before. Select the following key and press it to continue. Class 0001 is located in the HKEY LOCAL MACHINE SYSTEM CurrentControlSet Control 0001; 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 procedure.
If you wait until the next restart is complete, the screen brightness issue should be corrected and you should be able to regulate it.
