Setting the screen brightness correctly is very important. If you do a lot of work on your computer, an incorrect screen brightness level can negatively affect your eyes or quickly drain your device’s battery if it is not plugged in.

Fortunately, Windows 10 offers several easy ways to quickly adjust screen brightness, unlike previous versions of Windows. Let’s take a look at them

Change screen brightness using PowerShell.

You can use PowerShell to change the display brightness level in Windows 10. Here’s how to do it.

  • Open PowerShell.
  • Enter or copy the following command:

Note: In the above command, replace the BRIGHTNESS_LEVEL part with a percentage between 0 and 100. For example, the command below sets the screen brightness to 100%:

Options. This is a modern replacement for Control Panel, to change the screen brightness in Windows 10, follow these steps.

  • Open Windows Settings by pressing the Win I key combination or click on the gear icon in the Start menu.

  • Control Panel → Hardware and Sound → Power Options
  • In the lower right corner, adjust the position of the screen brightness slider.

If you click on the Power Scheme Setup link, you can customize the brightness level for both On Battery and On Line mode.

Second way

If for some reason you are unable to use the method indicated just above (for example, the “Windows Mobility Center” function is missing), you can try using another option.

There is a special Fn key on the laptop keyboard. it is used to type alternative commands. One of these commands is to adjust the brightness of the screen. Typically, brightness is indicated by a sun icon (filled and empty). Accordingly, in order to adjust the brightness, you need to hold down the Fn button, and then press either the filled sun to increase the brightness, or the empty sun to darken. You don’t need to press anything else.

Typically, the icons on the keyboard are located among the F1-F12 keys, less often they are located in other places.

The first way

The easiest way to start is best. In order to use it, you need 5 seconds of time.

At the bottom of the desktop, in the notification area (tray), there is a certain number of icons. Find the icon in the form of a battery and right-click on it, after which a menu will appear in which you need to select the item “Windows Mobility Center”.

A window with a lot of settings will open in front of you, including, for example, adjusting the sound and, of course, adjusting the brightness level of the laptop screen. Just move the slider to one side or the other, thereby adjusting the brightness to your liking or desire.

How to increase screen brightness on a laptop?

Those users who have previously worked exclusively on a desktop PC may be somewhat surprised to start working on a laptop. One of the main features of a laptop screen is that you simply cannot adjust the brightness on it in the same way as on a regular monitor. there is no separate button or wheel for this.

Tech Tips 5: Adjusting your Laptop Brightness

At the same time, by default, the screen brightness is usually such that it can cause significant inconvenience to the user’s eyes. it is at a relatively low level, as a rule, in order to save energy, since it is the screen that is one of the main consumers of energy.

Today I am going to show you how to decrease or increase the brightness on your device. I will show an example on Windows 7, although there is no difference between other operating systems, including the still popular XP. In addition, this manual is suitable for most modern laptops manufactured by companies such as Lenovo, Acer, Sasmung, Asus, Dell, Sony, etc.

Third way

If you are not looking for easy ways, you can use the third, slightly more difficult way.

Go to the control panel, select “System”. “Power supply”. “Power settings” (in some cases, the item is called “Setting the display off” or “Setting the power plan”). This will take you to a menu with which you can apply specific settings for your device. Including: brightness of the screen when using AC or battery, dimming the display after a certain time, putting the computer into sleep mode, etc.

It is worth remembering that in some laptop models, as a rule, expensive ones, there is an automatic brightness control function, which in turn depends on external lighting. This feature can be disabled.

In cases where the brightness does not change, do not rush to carry the laptop to service. The fact is that if it does not work from the mains, but from the battery, then the screen brightness may not exceed a certain level in order to save energy. This setting can usually be changed.

But if the brightness does not increase in any of the modes, this may really be due to the health of the screen.

Why the brightness of the screen on a laptop is not adjusted?

If the brightness does not change with hot keys (for example, fnF5 or fnF6), but at the same time it can be changed in the power settings, then most likely your laptop does not have a special application installed that activates the operation of special hot keys specifically for your laptop model.

How to adjust screen brightness

You can work, play or spend time on the Internet at the computer at different times of the day. For example, in the daytime in good lighting, the screen should also be bright enough so that you can normally see what is displayed on it, and you do not have to peer. But at night, on the contrary, it is better that it be a little muffled and not hit in the eyes.

Therefore, in this article, we will figure out how you can change the brightness of the screen on your computer or laptop in various ways.

Let’s start with the PC. Everything is quite simple here. Since there is no need to save battery power, the brightness is regulated here relatively rarely. Special buttons located on the monitor are used for this. They can be either below or slightly behind. Find the one with the sun and pointer icon. If the pointer is directed downwards. this is a decrease in brightness, up. an increase.

change, brightness, screen, laptop

Now I’ll tell you about laptops. Here, this procedure is used more often, especially if the device is disconnected from the mains and you need to slightly increase its battery life.

You can use the “Fn” key for this in various combinations, which differ depending on the manufacturer of your laptop. Let’s give examples for the most popular.

If you have ASUS then hold down “Fn” and press the “F5” button. to downgrade, or “F6”. to add brightness.

On Lenovo laptops, this is done using the up and down arrows. Press “Fn”. and then the desired button. Just pay attention, for example, in the screenshot, the arrow points up, and under it is an orange sun with a pointer down, which means that this button will reduce the brightness.

On HP, the combinations can be different or, as in the picture below, “Fn” and “F2-F3”. or “Fn” and “F9-F10”.

If you have a device from another manufacturer, then I think you understand which buttons to look for. They should have an image of the sun. one larger, the second smaller.

The second way of adjustment is through the “Control Panel”. Click on the “Start” button and select the desired item, for those who have Windows 7. If you have Windows 10 installed, then right-click on Start and select the item of interest.

Further, in the “Large icons” view mode, find and click on the “Power supply” item.

At the bottom of the window that opens there will be a slider that you move either to the right to the sun, or to the left, then the brightness decreases.

Further from the items in the left menu, select “Setting the display off”.

In this window, you can set the display brightness separately for the laptop to work on battery and mains. Remember that the smaller it is, the longer the charge will last. At the end, do not forget to click “Save changes”.

You can open the required window in another way. Click on the battery icon in the lower right corner and select the item of interest to us.

The third way is to adjust the brightness through the installed drivers for the video card. Find it in the list of Control Panel items and click on it.

Or expand hidden applications in the tray and click on the video card icon.

Then you need to select the item “Graphic characteristics”.

Another option is to right-click on an empty space on the desktop and select the desired item from the menu that opens.

Whichever option you choose, this window will open. I have a graphics card from Intel, so it looks like this. If you have a different manufacturer, the view of the window will be different.

Here, in the left menu, you need to find such an item so that the “Brightness” field appears in the middle area. Move the marker to the appropriate value. Then click “OK”.

That’s all. I think now you can easily adjust the brightness of your screen on a computer or laptop. As for me, adjustment using a combination of keys with Fn is the easiest, and you choose the method that suits you.

Decrease brightness on Windows 10 laptop

Immediately, we note that within the framework of this article we will only consider actions that only allow you to dim the brightness. If you need, on the contrary, to increase this indicator, read the separate instructions dedicated to this issue.

We will divide the rest of the tutorial into two sections. One of them will be useful for laptop owners, and the second. for users of stationary computers with monitors. The fact is that on them the screen brightness decreases in different ways. Techniques that can be used on a laptop will not have a positive effect on a PC.

Decrease screen brightness on stationary PCs

The list of methods for dimming the screen of external monitors is not as long as for laptops. In fact, there is only one method. using a special menu.

OS “parameters”

Using this method, you can not only reduce the brightness of the screen on your laptop, but also make other important settings. All actions will be performed in a special system window, where the operating system parameters are located.

    Click the “Start” button on the “Taskbar”. A new menu will then appear. In it, click on the “Parameters” button, which is depicted in the form of a gear.

Next, the required “Display” tab will automatically open. At the very top of the list of tab options is a bar for adjusting the brightness of the monitor. Hold the LMB slider and drag it to the left.

After setting the desired value, close all previously open windows. Note that when connecting multiple monitors, the desired brightness adjustment band will not be at the very top of the window, but in the middle.

Notification Center

This method is convenient in that it allows you to reduce the brightness of the screen without switching between windows. Everything is done quite simply.

    Click in the tray on the “Taskbar” on the “Notification Center” icon, which is located in the lower right corner of the screen.

A new window will appear where, as a rule, system notifications are displayed. There are also additional Windows settings. Click in such a window on the line “Expand”.

To close the “Notification Center”, just click again on the icon with the left mouse button (LMB), or do it anywhere in the “Desktop”.

Please note that this setting may not be present in older builds of Windows 10 (16xx and 17xx). If you are using one of them, just resort to any other method.

Methods to reduce screen brightness on Windows 10

For comfortable work at a computer or laptop, be sure to adjust the monitor screen properly. One of the important parameters is the brightness indicator. In this article, you will learn about the main methods to reduce it on devices running Windows 10.


In our opinion, the easiest way to reduce the brightness of a laptop screen is to use special keys. They are on every device. The bottom line is to press the “Fn” and “F2” keys simultaneously.

Please note that instead of the F2 key shown in the example, there may be another key. Which one depends on the manufacturer and model of your laptop. Often this is either one of the “F1-F12” keys, or the “Down” or “Left” button. Using the right combination, you can easily reduce the screen brightness.

“Mobility Center”

This method implies the use of a special system utility specified in the name of the method. In it, you can not only reduce the brightness, but also use additional functions of the OS.

    Press the “WindowsR” keys at the same time. In the “Run” snap-in window that opens, enter the command control. After that, press the “OK” button in the same window or “Enter” on the keyboard.

As a result, a small window with different settings will appear. The very first block will contain the desired strip for adjusting the brightness. Move the slider to the left to decrease it.

When the operation is complete, the Mobility Center window can be closed.


Using the buttons that change the brightness, you should set its level so that the test image is as similar as possible to the central picture, or meets the user’s needs (if you often work with very bright or dark pictures, or play games with a dark atmosphere, then it is more convenient to set the parameter values higher or lower than standard).

Sample pictures for adjusting brightness

Note! The display of samples for calibration depends on the settings and quality of the monitor, if there is any doubt about their correctness, then you can adjust the parameters by checking the examples on the screen of another computer or laptop installed nearby.

Splitting the screen into several parts

The tens workspace can be divided into 2, 3 or more parts, which is convenient when working on several projects and having a large monitor.

The ability to split is activated by default in Windows, to check this, you need to open the “Multitasking” tab in the system settings and make sure that all the sliders in the “Work with multiple windows” menu, as well as the “Pin windows” switch are active.

To dock the window on the left half of the screen, use the hotkeys Win ←, and to the right. Win →. The second way of snapping is dragging the window to the desired side.

To move between windows, use the arrow buttons, and to enlarge one of them to the full screen, use the “Enter” key.

Additional Information. To divide the work area into three or four parts, use the keyboard shortcuts Win → (or ←) and Win (or)

Adjusting the screen in Windows 10. how to improve the image on the monitor

The definition of the definition of the Windows 10 monitor occurs automatically immediately during the installation of the system, but if necessary, the display parameters can be changed independently, for this, new display adjustment tools have appeared in the top ten.

Through “Accessibility”

It is useful to know how to change the screen contrast on Windows 10 using the Accessibility feature, which allows you to choose a contrast settings scheme or customize your own, for this you need to:

  • open the “Options” menu “Start”;
  • go to the section “Special features;
  • in the “High Contrast” tab set a suitable theme.

Any contrast theme can be further customized for your convenience

Additional Information! You can flip the image on the monitor screen using the keyboard shortcut CtrlAlt, and rotate it 90 degrees. CtrlAlt →.

Through power settings

You can make the Windows 10 screen on laptops or tablets brighter using the power settings, for this:

  • right-clicking on the battery level indicator opens its pop-up menu;
  • in the lower left corner of the window, a tile button is found with the sun icon and the current brightness value in percent;
  • by clicking on a tile, change the desired parameter.

Important! Not all devices support this feature “tens”.


In a similar way, you can change the contrast of the monitor. The image should remain clear with visible black and white areas, but no sharp border between them.

Example of normal screen contrast

Changing the clarity of the image

A “blurry” picture on the screen can appear for several reasons, the most popular of which is the wrong resolution. It’s easy to figure out how to adjust the clarity of the Windows 10 monitor by changing the monitor resolution, for this:

  • clicking on the gear icon at the bottom left of the Start menu opens the Options menu;
  • select the item “System”;
  • in the opened menu “Display” find the item “Additional display parameters”;
  • in the window “Resolution” select the desired.

In most cases, the best value is marked with (Recommended)

Note! You may also need to change the resolution to change the size of the desktop icons, screensaver, or if games or applications do not open in full screen.

If changing the resolution does not bring any results, then the display scale is incorrectly set. It can be configured in the same menu, only in the section “Changing the size of text, applications and other elements”.

The image can also be scaled up or down when you scroll the mouse wheel while holding down the Ctrl key.

Through system parameters

With the help of the “Notification Center” it is also convenient to change the brightness, for this you need to open its menu by clicking on the icon located in the lower right corner of the monitor and click on the “Expand” link. There is a brightness slider under the settings tiles. (In older assemblies of “tens”, the brightness is changed by clicking on the tile with the sun icon and only completely between two values: 0 and 100).

Note! There is also a convenient function for switching the color gamut of the screen to night mode.

Brightness not working in Windows 10

In this manual, in detail about several ways to fix the situation when brightness adjustment in Windows 10 does not work. neither using the button in the notification area, nor adjusting the screen settings, nor the buttons to decrease and increase brightness, if any are provided on the keyboard of a laptop or computer (option (when only the adjustment keys do not work is considered a separate item at the end of the manual).

In most cases, the inability to adjust the brightness in Windows 10 is associated with driver problems, but not always with the video card: depending on the specific situation, this may be, for example, a monitor driver or a chipset (or even a completely disabled device in Device Manager).

Other reasons Windows 10 brightness control might not work

As a rule, the above options are enough to fix the problem with the availability of brightness controls in Windows 10. However, there are other options that are less common, but are found.


Many people use TeamViewer, and if you are one of the users of this program (see The best programs for remote computer control), then please note that it can also cause the brightness controls of Windows 10 to be unavailable, due to the fact that it installs its own monitor driver (displayed like Pnp-Montor Standard, Device Manager, but there may be other options), designed to optimize the connection speed.

In order to exclude this variant of the cause of the problem, do the following, unless you have a specific driver for a special monitor, but it is indicated that this is a standard (generic) monitor:

  • Go to the device manager, open the “Monitors” item and right-click on the monitor, select “Update drivers”.
  • Select “Search for drivers on this computer”. “Select from a list of already installed drivers”, and then select “Generic PnP Monitor” from the compatible devices
  • Install the driver and restart your computer.

I admit that a similar situation can be not only with TeamViewer, but also with other similar programs, if you use them, I recommend checking.

Monitor Drivers

I have never encountered such a situation, but theoretically it is possible that you have some kind of special monitor (probably very cool) that needs its own drivers, and not all of its functions work with the standard ones.

If what is described looks like what is in fact, install the drivers for your monitor from the official website of its manufacturer or from the disc included in the package.

Chipset Drivers

If you have not installed on your computer, especially the laptop, the chipset driver from the official website of the laptop manufacturer, as well as additional hardware and power management drivers, many things (sleep and exit, brightness, hibernation) may not work normally.

First of all, pay attention to the Intel Management Engine Interface drivers, Intel or AMD Chipset driver, ACPI drivers (not to be confused with AHCI).

At the same time, very often with these drivers it happens that on the website of the laptop manufacturer they are older, for the previous OS, but more efficient than those on which Windows 10 is trying to update and update them. In this case (if after installing the “old” drivers everything works, but after a while it stops), I recommend disabling the automatic updating of these drivers using the official utility from Microsoft, as described here: How to disable updating Windows 10 drivers.

Attention: the following point may apply not only to TeamViewer, but also to other programs for remote access to a computer.

Disabled “Generic PnP Monitor

This version of the reason that the brightness does not work (there are no adjustments in the notification area and the brightness change in the screen parameters is inactive, see the screenshot above) is more common than others (although it seems illogical to me), and therefore we will start with it.

  • Start Device Manager. To do this, right-click on the “Start” button and select the corresponding item in the context menu.
  • In the “Monitors” section, pay attention to the “Generic PnP Monitor” (and possibly some other).
  • If you see a small arrow next to the monitor icon, it means that the device is disabled. Right-click on it and select “Engage”.
  • Restart your computer and then check whether the screen brightness can be adjusted.
READ  Installing the operating system on a new laptop

This variant of the problem is often found on Lenovo and HP Pavilion laptops, but I’m sure the list is not limited to them.

Video card drivers

The next most common reason for not working brightness controls in Windows 10 is problems with the installed video card drivers. specifically, this can be caused by the following points:

  • Installed drivers that Windows 10 installed itself (or from the driver pack). In this case, install the official drivers manually, after removing those that are already there. An example for GeForce graphics cards is given in Installing NVIDIA Drivers on Windows 10, but for other graphics cards it will be the same.
  • Intel HD Graphics driver not installed. On some laptops with a discrete video card and integrated Intel video, its installation (and it is better from the laptop manufacturer’s website for your model, and not from other sources) is necessary for normal operation, including brightness. At the same time, in the device manager, you may not see disabled or non-working devices.
  • For some reason, the video adapter is disabled in the device manager (just like in the case of the monitor described above). In this case, the image will not disappear anywhere, but its adjustment will become impossible.

After the steps taken, restart the computer before checking the operation of changing the screen brightness.

Just in case, I also recommend to go to the display settings (through the menu of the right click on the desktop). Display. Additional display settings. Graphics adapter properties and see which video adapter is listed on the “Adapter” tab.

If you see the Microsoft Basic Display Driver there, then the matter is clearly either in the video adapter disabled in the device manager (in the device manager in the View item, also enable Show hidden devices if you do not immediately see problems), or in some kind of driver failure Hardware issues aside (which rarely happens).

Manually adjusting the monitor backlight

For desktop computer users, the screen illumination parameters can be adjusted on the display itself. For example, we will use the LG Flatron W1943SS monitor. To adjust the lighting, you need to go to its menu. To do this, press the MENU key on the monitor control panel.

Then press the AUTO / SET key. The brightness adjustment window should open, in which you can change it.

I would also like to note that the monitor settings do not depend on which OS or driver is installed. They are regulated exclusively in the monitor. Each monitor from a different manufacturer has its own manual settings. You can find out the details of adjusting the lighting parameters of the screen of a particular monitor in the manual that comes with the sale or can be downloaded electronically on the manufacturer’s website.

An example of adjusting the laptop backlight using the Fn key

For example, we will use a Lenovo s110 netbook with Windows 7 operating system.

It uses the Fn modifier key in combination with the ← and → cursor keys to adjust the backlight. To increase the backlight of Lenovo s110 laptop, you must use the key combination Fn →. To lower the backlight, you need to use the combination Fn ←.

As the backlight goes up and down, you will see how the value of the graphical indicator changes. The Hotkey Features program is responsible for this indicator.

As you can see, it is quite easy to increase or decrease the lighting settings of the laptop screen using the “Fn” key. You can use this example on other laptops, since the principles of using the modifier keys are the same.

Specifically, on Samsung NP350 laptops, the keyboard shortcuts are:

  • to increase brightness. Fn F3;
  • to decrease. Fn F2.

Learn to adjust screen brightness in Windows 7

Often, users of the Windows 7 operating system are faced with the problem of adjusting the brightness of the screen. To fix this problem, we will take a look at all the available ways to adjust the display brightness in Windows 7. Adjusting the screen backlight is a fairly simple process that even a novice user can handle. After reading the material, you can independently adjust the brightness of a laptop or stationary computer.

Brightness control using standard Windows 7 tools

To set the brightness of a laptop or candy bar by standard means of sevens, the first step is to go to the Control Panel. You can go to the Control Panel through the “Start” menu or type the command control in the “Run” program

After starting the Control Panel, you need to go to the “System and Security” section.

Next, go to the section “Power supply”.

You can also go to the power plan settings and set the brightness at which the laptop will operate on battery or mains.

Changing the screen lighting settings using the video driver

Another interesting way to change the display lighting is by adjusting it with the graphics card driver. For our example, we will consider a driver from Nvidia. To open the parameters of the video card driver, you need to right-click on an empty space on the Desktop. A context menu should appear.

Now in this panel you need to go to the menu “Video \ Adjust color settings for video”.

In the color adjustment menu, go to the column “2. How to adjust color settings ”and select the switch“ With NVIDIA settings ”. By selecting these parameters, you will be able to adjust four properties, including the brightness of the display. To increase or decrease the brightness of the display, drag the slider towards the plus or minus and you will see how the screen backlight changes.

Such programs that adjust the screen lighting using the video adapter driver are also available from the manufacturers of Intel and AMD video cards.

Also in the vastness of the network you can find many programs that adjust the display backlight. All such programs work through an appeal to the video adapter driver. That is, in essence, they do what you can do in the control panel of a video card (in our case, Nvidia). The most interesting of all such programs is F.lux. Its main feature is the automatic adjustment of the display backlight, which depends on the time of day.

Summing up

This material shows that even a novice PC user can increase and decrease the display brightness in Windows 7. And we hope that our material will help you learn how to change the brightness of your computer monitor.
