Which driver is responsible for screen brightness. The brightness on the laptop cannot be adjusted: tips for solving the problem

Not long ago I encountered one very unpleasant problem - on all my laptops the ability to adjust the screen brightness suddenly disappeared. Be it your favorite Fn keys, or the standard brightness slider in the computer settings. The very concept of “brightness” in the screen settings disappeared and the main working machine was stuck in dark mode.

The way out of this situation, as it turned out, is quite simple - the problem lies in the drivers. After scouring the forums, I managed to find a few ideas that led to a simple solution. For the brightness control to work properly, you need to reinstall the driver... no, not the video card, but the monitor!

How to do this in the easiest way?

  1. Right-click on an empty space on the Desktop and select “Screen Resolution” from the menu that opens.
  2. In the screen resolution settings we find the “Advanced settings” link - it’s on the bottom right.
  3. In the window that opens, open the “Monitor” tab, then click on “Properties”. Most likely, the system will ask permission to intervene, we allow it.
  4. In the window that opens, open the “Driver” tab and click on the “Roll Back” button. Voila, brightness control is back!
  5. Click on “Ok” several times and enjoy the result.

That's it, kickbacks are saving our lives again!

Important! When using the DRP program, be sure to work in manual and expert mode! Otherwise, in addition to updating drivers, you will also get a ton of useless programs! To do this, when starting the program, check the “Settings” box, select “Expert Mode”, check the monitor driver box and click “Install” at the bottom of the screen. More details in the screenshot below.

Detailed instructions for working with the driver package are available at the link: .

P.S.: trying to find the cause of such glitches on one of the computers, I noticed that the monitor driver had a digital signature from TeamViewer. It is quite possible that the problem lies precisely in this program - it was installed on each of the computers being repaired. It might be worth contacting their tech. support.

      Did you manage to restore the brightness control? The same thing happened to me today. When you press Fn+Up|Down, the brightness adjustment slider decreases by only one position from the maximum. That's it, it doesn't go any lower.

      So. Reinstalling Easy Display Manager did not help. Jerking the battery (you never know) didn't help either. Having searched the Internet for a solution, I found out that the problem can be said to be global! TP, help out! Don’t drag a beech tree to a storage center just because of this, where it can lie for a week; if of course the problem is in the hardware, then you will have to: (Hey, people! Has anyone solved this problem? I suspect that restoring the system will not help, and there is no desire to do it, because a lot will have to be reinstalled/configured. In general, I am beginning to suspect that W7Starter, due to its truncated nature, contains quite a few problems. I still have problems with the Ethernet network card. But I will analyze them for now, and then write them down.

        It’s not a matter of W7Starter, I installed the maximum one and also had the same problem and the hardware was hard to work with. I think it’s a matter of drivers and there were glitches with this on W7Starter.

How to adjust screen brightness on a laptop?

Master's answer:

If you are an active PC user, and therefore spend a lot of time in front of the monitor, you probably often think about how you can adjust the screen brightness. The eyes can become very tired and sore, fatigue appears faster and irritability increases. All this can be easily solved by correctly setting the screen brightness intensity. For example, you work a lot during the day, natural (and, if necessary, artificial lighting) is quite good. In this case, it is recommended to make the screen as bright as possible. These simple tips will help you significantly increase your productivity and minimize health problems. It's very easy to adjust the screen brightness yourself.

All operating systems use special keys designed specifically to adjust screen brightness. Use them and find the best option for your eyes. The "Fn" button is designed for exactly this. Press it and hold it for a while, while simultaneously adjusting the “brightness” of the screen with another button with an image of the brightness increase symbol. This combination of functions allows you to optimally organize the placement of buttons on the keyboard and guarantees quick access to frequently requested functions. This is the easiest and most accessible way to adjust the brightness.

Want to challenge yourself and learn more about your laptop's capabilities? Take a different, more difficult (compared to the previous) path.

Select "Control Panel" if your laptop is running Windows operating system. A service with a similar name exists in other systems. Find the “Screen” shortcut (tab). Click on it with your mouse. In the expanded window there is a slider for adjusting the brightness. Let's say you want the screen to become lighter. Move the slider to the right until you reach the desired limit in lighting.

Feel confident and ready to “move mountains” in the settings of your laptop? You can safely use specially designed programs that come with laptops. These programs will definitely be equipped with powerful video cards. Their purpose is to change video card settings on the fly. The variety is determined by the video card model. They often operate in the background, and an icon with their image is placed in the system tray. To enter the settings, click on the icon using any mouse button. A context menu or window will instantly open in front of you. Select the settings item and adjust the screen brightness using the slider. This is a little more complicated, but more interesting in terms of exploring the capabilities of your laptop.

It is not surprising that many users want the computer screen to display the highest quality and most acceptable image for a particular user’s eye under certain lighting conditions. This can be achieved, among other things, by adjusting the brightness of the monitor. Let's find out how to handle this task on a PC running Windows 7.

One of the easiest ways to change screen brightness is to make adjustments using the monitor buttons. You can also solve this problem through the BIOS settings. But in this article we will focus on the possibilities of solving the problem using Windows 7 tools or using software that is installed on a computer with this OS.

All options can be divided into 3 groups:

  • Adjustment using third-party software;
  • Adjustment using the video card management application;
  • OS Tools.

Now we will look at each group in more detail.

Method 1: Monitor Plus

First, we will learn how to solve the stated problem using a third-party program designed to control the Monitor Plus monitor.

Method 2: F.lux

Another program that can work with the settings of the monitor parameter we are studying is F.lux. Unlike the previous application, it is capable of making adjustments automatically for specific lighting, according to the daily rhythm in your area.


Method 3: Video card management program

Now we’ll find out how to solve the problem using a program for controlling a video card. As a rule, this application is available on the installation disk included with the video adapter and is installed along with the drivers for the video card. We will look at the actions using an example.


Method 4: Personalization

The settings we are interested in can be adjusted using exclusively OS tools, in particular the tool "Window color" In chapter "Personalization". But for this, one of the Aero themes must be active on the PC. In addition, it should be noted that the settings of not everything displayed on the screen will be changed, but only the borders of the windows, "Taskbars" and menu "Start".


Method 5: Color Calibration

You can also change the specified monitor parameter by enabling color calibration. But you will also have to use the buttons located on the monitor.

The advantage of working on a laptop is the portability of this device. This means that you can sit at the computer not only at home, but also on the street. Daytime street lighting makes the work of the eyes somewhat more difficult. Increasing the brightness of the laptop screen will help correct the situation.

Increase brightness on laptop

There are several ways to increase the brightness of your laptop monitor.

  1. The easiest way is to increase the brightness using the keyboard. To do this, hold down the Fn button and simultaneously press several times the button on which a rectangle is drawn, and inside it is a sun or a large star. As a rule, such a picture is located on the F6 button, which is located in the very top row of the keyboard.
  2. Another way is to click on the Start button with your mouse cursor. In the drop-down list that appears, find the “Control Panel” item. A window will appear in front of you. In it you must select the line “System and Security”. The next step is to select the “Power Options” line. A window will appear in front of you again, at the very bottom of which you will see a scale. This scale reflects the brightness of your laptop screen. Pulling the slider to the right will increase the brightness.

It should be remembered that increasing the screen brightness also increases the battery consumption of your laptop.

In this context, it will also be useful to know how to change the amount of time at which your laptop will automatically dim its screen to save battery power.

Adjusting the screen dimming speed

Setting this parameter repeats the path you have already taken: “Start” - “Control Panel” - “System and Security” - “Power Options”. But now you are not looking down the window, but in the center, where several meal plans are presented. Each plan comes with a “Customize Meal Plan” feature. By selecting this function, you can adjust the time after which the screen will automatically darken if the laptop is running on battery power or on mains power. When the parameters are changed to your liking, do not forget to confirm them with the “Save Changes” button.

The ability to manipulate color saturation on a laptop screen pays off. You not only preserve your vision and take care of your health, but at the same time ensure maximum convenience and productivity in your work process. Reducing brightness contrasts helps minimize power and resource consumption of your device.

The Windows operating system is equipped with all possible functions for ease of use, but we do not always know how to use them. One of the easiest and fastest ways to increase or decrease screen brightness is to use the functionality on the taskbar. To launch the required function, hover over the battery display icon on the taskbar and right-click, select “Windows Mobility Center” from the context menu. A window will pop up where the first item from left to right will be the “Screen Brightness” setting. By moving the slider, you will adjust the most pleasant contrasts for your vision.


You can quickly, rather instantly, increase the brightness without using a mouse directly on the laptop keyboard. In each model, these keys may differ slightly, but the principle is the same. Find the “Fn” key and the up-down or left-right arrows. The multi-sided arrows should show a sun with a directional pointer. If you press the combination “Fn” + arrow for changing screen brightness, you will get the desired result.


You can independently create and configure a power plan that will work according to the parameters you specify. The laptop itself will dim or restore the screen brightness after a specified period of time. To create a graph of laptop backlight brightness separately for operation on mains power and battery power, proceed as follows.

  1. In the “Start” menu, select “Control Panel”;
  2. Next, go to the “System and Security” item;
  3. Select the “Power Options” section;
  4. After clicking “Set display off”, you will be presented with a panel where you can specify the desired settings and save them.


If you cannot find the required option, and the image is dim and unattractive, you may need to update your operating system and install drivers.


When setting the brightness level from the battery and from the network, you need to understand that the saved parameters are valid only for the current power plan. In order for your settings to remain in effect and no longer create discomfort, you need to configure all three standard plans that are provided by default in every laptop.

In the Windows operating system, you can adjust the screen brightness without any difficulty. This is done using one of the available methods. However, sometimes malfunctions occur, which is why this parameter simply cannot be adjusted. In this article we will talk in detail about possible solutions to the problem that has arisen, which will be useful for laptop owners.

First of all, you should understand how the brightness changes on laptops running Windows. There are several different adjustment options, all of which require certain actions.

Function buttons

The keyboards of most modern devices have function buttons that can be activated by pressing Fn + F1F12 or any other marked key. Often the brightness is changed by a combination of arrows, but it all depends on the equipment manufacturer. Carefully examine the keyboard to ensure that it contains the required function key.

Video card software

All discrete and integrated graphics adapters have software from the developer, where many parameters are finely configured, including brightness. Let's consider the transition to such software using an example "NVIDIA Control Panel":

Standard Windows feature

Windows has a built-in feature that allows you to customize your power plan. Among all the parameters, there is also a brightness configuration. It changes as follows:

In addition, there are several additional methods. Detailed instructions for them are in our other material at the link below.

Solving the problem with adjusting brightness on a laptop

Now that we have understood the basic principles of brightness adjustment, let's move on to solving problems associated with changing it on a laptop. Let's look at solutions to the two most popular problems that users face.

Method 1: Enable Function Keys

Most laptop owners use a key combination to adjust the brightness value. Sometimes when you click on them, nothing happens, which indicates that the corresponding tool is simply disabled in the BIOS or there are no suitable drivers for it. To solve the problem and activate the function keys, we recommend that you refer to our two articles at the links below. They contain all the necessary information and instructions.

Method 2: Update or rollback video card drivers

The second common malfunction that causes failures when trying to change the brightness on a laptop is incorrect operation of the video driver. This happens when updating/installing the wrong version. We recommend updating or rolling back the software to a previous version. A detailed guide on how to do this can be found in our other materials below.

We advise owners of the Windows 10 operating system to refer to an article from another of our authors, where you will find instructions on how to fix the problem in question in this particular version of the OS.

Hello.

A fairly common problem on laptops is the problem of screen brightness: it either does not adjust, then changes on its own, then everything is too bright, or the colors are too weak. In general, it’s just a “sore topic.”

In this article I will focus on one problem: the inability to adjust brightness. Yes, this happens, I myself periodically encounter similar questions in my work. By the way, some people neglect to adjust the monitor settings, but in vain: if the brightness is too low (or too high), the eyes begin to strain and get tired quickly.

So where to start solving the problem?

1. Brightness adjustment: several ways.

Many users, having tried one method of adjusting the brightness, come to an unambiguous conclusion - it cannot be adjusted, something has “frozen” and needs to be repaired. Meanwhile, there are several ways to do this, besides, once you set up the monitor, you can not touch it for quite a long time, and you won’t even remember that one of the methods is not working for you...

I suggest trying several options; I’ll discuss them below.

1) Function keys

The keyboard of almost every modern laptop has functional buttons. They are usually located on the F1, F2, etc. keys. To use them, just press the button FN+F3 For example (depending on which button you have the brightness icon on. On DELL laptops, these are usually the F11, F12 buttons).

Function buttons: brightness adjustment.

If the screen brightness has not changed and nothing appears on the screen (no control) - move on...

2) Taskbar (for Windows 8, 10)

In Windows 10, you can very quickly adjust the brightness by clicking on the power icon in the taskbar, and then left-clicking on the rectangle with brightness: adjust its optimal value (see screenshot below).

3) Via control panel

First you need to open the Control Panel at: Control Panel\All Control Panel Items\Power Options

4) Via video card driver

The easiest way to open the video card driver settings is to right-click on the desktop and select graphics characteristics from the context menu (in general, it all depends on the specific driver; sometimes you can go to its settings only through the Windows control panel).

In the color settings, there are usually parameters for setting: saturation, contrast, gamma, brightness, etc. Actually, we find the desired parameter and change it to suit our requirements.

2. Are the function buttons enabled?

A very common reason why function buttons (Fn+F3, Fn+F11, etc.) do not work on a laptop is the BIOS settings. It is possible that they are simply disabled in the BIOS.

The choice of section where to enter the BIOS depends on your manufacturer. Here (within the framework of this article) it is unrealistic to give a universal recipe. For example, in HP laptops - check the System Configuration section: see if the Action Keys Mode item is enabled there (if not, switch it to Enabled mode).

Action keys mode. HP laptop BIOS.

On DELL laptops, function buttons are configured in the Advanced section: the item is called Function Key Behavior (you can set two operating modes: Function Key and Multimedia Key).

3. Lack of key drivers

It is possible that the functional buttons (including those responsible for screen brightness) do not work due to a lack of drivers.

Give a universal name for the driver in this question (which you can download and everything will work)- it is forbidden (by the way, there are some of these on the Internet, I highly recommend not using them)! Depending on the brand (manufacturer) of your laptop, the driver will be called differently, for example: in Samsung it is “Control Center”, in HP it is “HP Quick Launch Buttons”, in Toshiba it is Hotkey utility, in ASUS it is “ATK Hotkey” .

4. Incorrect drivers for the video card. Installing "old" working drivers

If everything worked as it should for you before, and after updating Windows (by the way, when updating, you usually always install a different video driver)- everything started to work wrong (for example, the brightness slider moves across the screen, but the brightness does not change)- it makes sense to try to roll back the driver.

By the way, an important point: you must have old drivers with which everything worked well for you.

How to do it?

1) Go to the Windows Control Panel and find Device Manager there. You open it.

Updating the driver in Device Manager

Then select "Browse this computer for driver software."

By the way, it is possible that the old driver (especially if you just upgraded from an older version of Windows rather than reinstalling it again) already on your PC. To find out, click the button at the bottom of the page: “Select a driver from the list of already installed drivers” (see screenshot below).

Where to look for drivers. Directory selection

Then just point to the old (different) driver and try using it. Very often this solution helped me, because old drivers sometimes turn out to be better than new ones!

List of drivers

5. Windows OS update: 7 --->10.

By installing, say, Windwows 10 instead of Windows 7, you can get rid of problems with drivers for function buttons (especially if you can't find them). The fact is that the new Windows OS has built-in standard drivers for function keys.

For example, the screenshot below shows how you can adjust the brightness.

I should note, however, that these "built-in" drivers may be less functional than your "native" ones ( for example, some unique functions may not be available, for example, auto-adjustment of contrast depending on external lighting).
