Spontaneous change in monitor brightness - the laptop changes the brightness itself! Why? Reducing monitor brightness on laptops and computers If you are using a video adapter from NVIDIA

Hello.

The brightness of the monitor screen is one of the most important details when working at a computer, which affects eye fatigue. The fact is that on a sunny day, usually the picture on the monitor is faded and it is difficult to distinguish it unless you turn up the brightness. As a result, if the brightness of the monitor is low, then you have to strain your eyesight and your eyes quickly get tired (which is not good...).

In this article I want to focus on adjusting the brightness of a laptop monitor. This can be done in several ways, let's look at each of them.

Important point! The brightness of a laptop screen greatly affects the amount of energy consumed. If your laptop is running on a battery, then turning up the brightness will drain the battery a little faster. Article on how to increase laptop battery life:

How to increase laptop screen brightness

1) Function keys

The easiest and fastest way to change the brightness of your monitor is to use the function keys on your keyboard. As a rule, you need to hold down the function button Fn+arrow(or range F1-F12, depending on which button has the brightness icon - “sun” on it, see Fig. 1).

One small note. These buttons do not always work; the reasons for this are most often:

1. uninstalled drivers (for example, if you installed Windows 7, 8, 10, then by default drivers are installed on almost all devices that will be recognized by the OS. But these drivers work “wrong”, including often the function keys do not work!) . An article on how to update drivers in auto mode:
2. these keys can be disabled in the BIOS (though not all devices support this option, but it is possible). To enable them, enter the BIOS and change the appropriate settings (article on how to enter the BIOS:).

2) Windows Control Panel

You can also change brightness settings through the Windows Control Panel (the recommendations below are relevant for Windows 7, 8, 10).

1. First you need to go to control Panel and open the section " Equipment and sound"(as in Fig. 2). Next, open the “Power Options” section.

In the power section at the very bottom of the window there will be a “slider” for adjusting the brightness of the monitor. By moving it to the desired side, the monitor will change its brightness (in real time). You can also change the brightness settings by clicking on the link “ Setting up the power plan«.

3) Adjusting brightness and contrast settings in drivers

You can adjust brightness, saturation, contrast and other parameters in the settings of your video card drivers (if, of course, they were installed 🙂).

Most often, the icon needed to enter their settings is located next to the clock (in the lower right corner, as in Fig. 4). Just open them and go to display settings.

By the way, there is another way to enter the graphics settings. Just right-click anywhere on the Windows desktop and the context menu that appears will contain a link to the parameters you are looking for (as in Fig. 5). By the way, it doesn’t matter what video card you have: ATI, NVidia or Intel.

Users of Windows 7/10 operating systems often need to adjust the screen brightness. This is a fairly simple procedure, but some owners of computers, laptops and tablets often have difficulty performing it. In this article we will look at all possible ways to adjust the brightness of the monitor, so that after familiarizing yourself with the material, even novice users can easily carry out this operation.

Adjusting screen brightness using standard Windows 7/10 tools

The simplest and most obvious path to brightness settings within the operating system itself is through the Windows Control Panel. We go into it using the Start menu, and then select the “Power Options” section (in the “Small Icons” or “Large Icons” display mode).

At the bottom we see the “Screen Brightness” slider, by moving which you can increase or decrease the backlight intensity of your monitor.

It is also possible to go directly to the settings of the selected power plan. Here, if you are using a laptop, you can separately adjust the brightness for battery and mains modes.

Owners of modern portable devices running Windows 10 should be aware of one more trick. Many new laptops are equipped with a light sensor that allows adaptive adjustment of screen brightness. That is, the “ten” automatically adjusts the backlight level depending on the amount of light hitting the sensor. It is clear that this function does not always work correctly, often setting an inappropriate brightness level. Therefore, the question quite reasonably arises of how to disable it. You can do this by clicking on the “Change advanced power settings” link in the settings of the current power plan.

In the window that opens, expand the “Display” tab and switch the “Enable adaptive brightness control” option to the “Off” position. Click the “Apply” button to save the settings.

Adjusting brightness using the video card driver

Another proven way to change the screen brightness is to adjust it using the video card driver. Let's look at this method using Nvidia drivers as an example. Right-click on the desktop and select “Nvidia Control Panel” from the context menu.

In the settings tree on the left, open the “Display” section and select the line “Adjust desktop color settings” from the drop-down list. In the right area, set the switch to the “Use NVIDIA settings” position and move the “Brightness” slider in one direction or another, thereby increasing or decreasing the backlight strength.

Adjusting the display brightness on a laptop

Laptop computers allow you to control many settings using keyboard buttons. Typically, a special “Fn” key is used for these purposes, working in combination with other keys. For example, adjusting the screen brightness on a Samsung RV515 laptop is done by pressing the following button combinations:

On different laptop models, the backlight intensity is adjusted using different key combinations. The combination of Fn and any of the function keys in the F1-F12 range is often used. You can learn more about ways to change the brightness of your laptop's display in its manual.

Setting the brightness on the monitor itself

In most cases, modern monitors have their own buttons on the body for controlling settings for color, contrast, brightness and other parameters. As an example, consider the LG IPS236 monitor. It has several touch buttons on the control panel, press any one and get to the “Monitor Setup” menu.

Select the first item “Menu” and see the scales for adjusting brightness, contrast and clarity. Using the arrows, move to the desired line and set the optimal value.

The issue is resolved in a similar way with other monitor models, only the configuration and location of the button panel differ.

In principle, many screen settings, including brightness, can be adjusted in the monitor itself. And here it will no longer matter what operating system is installed on the computer. Instructions for manually setting parameters are included with the monitor upon purchase; it can also be downloaded from the manufacturer’s website in electronic form.

Conclusion

That's all we wanted to tell you about methods for adjusting screen brightness on a desktop computer and laptop. We hope that after reading this material you will no longer have questions about how to increase or decrease the brightness of any type of display with just a few simple steps.

The brightness of a laptop screen is one of the most important parameters. Setting the brightness correctly not only helps you see the laptop image clearly and correctly identify colors, but also protects your eyesight, since too high a value “burns out” your eyes, and too low makes them strain more. Also, reducing the brightness will save battery power. But most users do not immediately find the right button. In this article I will show you how to change the brightness on a laptop. These methods are suitable for most models, be it Lenovo, Samsung, Acer or Asus.

There are a large number of ways to reduce or increase screen brightness. Here are the most popular ways to change the display brightness on a laptop:

Method 1: Keyboard shortcut

Most laptop models have a special button - « Fn", function key . It allows you to control many important computer parameters using special combinations. To lower or raise the screen brightness using your keyboard, you will need:

1. You need to find it at the top of the keyboard, in the system keys area « F1-F12" buttons on which the corresponding icons for adding or decreasing brightness will be drawn.
2. Press the key combination “Fn” and the key you need. In this case, it is better to first press the function key, and only then one of the keys « F1-F12".

This method is the most effective and works on almost all laptop models and allows you to increase or decrease the saturation of the monitor in a few seconds.

Method 2: tray icon

In the tray (bottom right edge of the screen), among other icons such as the clock, Internet status, language, there is a power icon. Using it you can open a very convenient menu in which you can change the brightness of the screen. Need to:

1. Click on the battery icon in the tray using the right mouse button.
2. In the drop-down menu, click on the lowest item "Mobility Center"Windows".
3. A very convenient window will open in front of you. Using the slider, you can increase or decrease the brightness on your laptop.

Method 3: For Windows 10

In this operating system, you can remove or increase the brightness on your laptop in an even simpler way than the previous one.

1. Click on the power icon (battery in the lower right part of the screen) with the left mouse button.
2. There is a brightness option in the drop-down menu. By clicking on the icon, you can set it to 0, 25, 50, 75, 100%.

This method is very convenient, as it allows you to very quickly reduce or increase the color saturation on the screen in just a couple of clicks.

Method 4: From the Desktop

You can change the brightness directly from your desktop. To do this you need:

1. Right-click on the space unoccupied by shortcuts on the desktop.
2. In the drop-down menu, click on “Display Settings” in Windows 10 or “Screen Resolution” for Windows 7, based on the version of the Operating System installed on your computer.
3. In the window that opens, you need to find the slider responsible for the brightness of the screen. By moving it left and right, you can turn down or turn up the brightness on your laptop.

Method 5: Control Panel

You can more precisely adjust the screen brightness control using the “Control Panel”. For this:

1. Launch Control Panel. To do this, type the appropriate phrase in the search bar. Or, if you have Windows 7, the launch panel button is located in the Start menu.
2. Go to the "System" or "System and Security" tab.
3. Then click on the “Power Options” line.
4. There you need to select the installed power plan and click on settings. In the menu that opens, you can not only change the brightness, but also configure the display to turn off and put the computer into sleep mode.

What to do if the brightness does not decrease or increase

There are several reasons why this problem may occur. The most common of them:

Reason 1: Light sensor

Some expensive laptop models have a light sensor that changes brightness depending on the light level. Often this sensor makes it difficult to set the screen brightness to a comfortable level for the user. And sometimes this sensor fails.

To solve this problem, you need to disable the sensor in your laptop's settings and use one of the methods described above to set the optimal monitor brightness level.

Reason 2: Backlight system malfunction

This is true for older laptop models, where glass tubes are used as backlighting rather than LEDs. The fact is that the resource of these elements is limited and if they fail, the backlight turns off completely, but the user can see the image on the screen and think that the brightness level is set to the minimum value.

It is necessary to contact a specialized service, where professionals will replace the damaged parts, but this procedure is not cheap due to the inaccessibility of spare parts.

Reason 3: viruses

It is extremely rare, but worth mentioning. Some viruses are able to control the brightness of the screen, which interferes with normal operation.

You need to scan your computer with an antivirus, or preferably several. To prevent re-infection, it is best to have an antivirus with real-time protection.

It is worth recalling that some of the described methods may differ or may not work at all on your computer due to different versions of the installed Operating System and the individual characteristics of the laptop. So if one method doesn't work on your computer, don't despair, try another. I hope you liked the article.

The bright screen of your computer or laptop can negatively affect a person. For example, when constantly near the display, especially at nightfall, due to the excessive brightness of the screen, the vital hormone melatonin is suppressed, which begins to be produced in smaller quantities and ceases to signal timely preparation for sleep. This is followed by a decrease in performance. It is for this reason that the most appropriate solution would be to reduce the brightness of the monitor by at least half. If you use a laptop or phone, you can save additional battery power. In this article you will learn how to reduce the brightness of your monitor when working on a computer or laptop.

Changing brightness settings on a laptop

It is worth taking into account that depending on the manufacturer, the overall brightness level and possibilities for customization will vary greatly.

Option 1 – Change the brightness level using hotkeys

In the vast majority of laptops, in order to change the brightness, you need to use a combination of several function keys. For example, by holding down the “Fn” button, you can use the arrows to adjust the brightness level of the monitor. Despite the fact that along with the Fn button there may be completely different input keys, the screen brightness symbol is always depicted as a sun symbol.

Option 2 – adjust brightness using the control panel

You can also change the brightness using the display settings through the control panel. In this case, you need to do the following:

1. Go to the Control Panel menu (in the Windows 10 search, enter “panel” and select “Control Panel” from the list).
2. Open the screen control option – the icon labeled “Screen”.
3. In the window that opens, find and open the “Brightness Settings” item.
4. After which, you will find yourself in the laptop power consumption settings menu. At the bottom of the window that appears there will be a slider that is responsible for brightness settings.
5. Next, you will need to set the monitor brightness level to a comfortable level and exit the settings. All new settings will take effect immediately.

In my case, there were no “Display” settings, there was an Intel HD graphics setting:

Option 3 – change the brightness using the video card driver

All modern laptops run on a basic video adapter from Intel, AMD or Nvidia. It is with the help of the driver preinstalled on your laptop that you have the right to independently change the display color settings, making it brighter or more saturated.

If you are using a video adapter from AMD

Using a driver from AMD, you can change the standard settings for image clarity on the display. Due to the fact that the company has released a huge number of driver updates, the items in the settings panel may vary greatly. For example, in Catalyst 10.2, to apply the new options for brightness settings, you need to visit the Color menu. To get to the driver settings menu, just short-click the right mouse button while on the desktop and select “Catalyst Control Center”.

If you are using a video adapter from NVIDIA

1. Right-click on the desktop and select “NVIDIA Control Panel” from the context menu.img8
2. In the navigation panel that appears, in the left row, select “Customize desktop color settings.”
3. You will be offered several displays to choose from, if you have more than one, where you will need to select the one you need, and then click on the “Use NVIDIA Settings” item. After which you will have access to display settings, which include brightness, contrast and gamma. For all the specified settings to take effect, you will need to click the “Apply” button.

Option 4 – If all of the above options do not suit you

If you were still unable to adjust the display brightness using the function keys or all the adjustments made to the driver were ineffective, then most likely you are faced with a problem with your video card driver. This can happen after updating drivers to the latest version. One way to resolve this problem may be to roll back the video card software to a previous version or completely remove it and clean install it.

Changing the brightness of the monitor on the computer

If you are using a desktop computer (PC), all of the above options are also practical. However, for user convenience, it would be better to use the monitor's functions. This way you can calibrate your brightness settings much better. Each monitor must have control buttons. As a rule, their number is from 5, among them are: presets, brightness/contrast, menu, output and turning off the monitor.

Naturally, everything depends solely on the model. Therefore, try to configure it “at random”, even if you don’t get to the menu you need, press the exit button and try again until you understand how to manage the settings of your monitor.

Brightness settings are located in the monitor menu; the menu for each monitor is also different:

On a sunny day, you need to raise the curtains and change the brightness of the display, reducing the overall value to 15-30%. It is not recommended to increase the brightness level to more than a third of the maximum value. If the sun's rays fall directly on the screen, you need to turn the brightness to maximum.

Many users, either due to duty or for personal reasons, have to spend quite a lot of time at the computer. And not the least role in the comfort of work is played by the brightness and contrast of the image on the monitor or laptop screen. Oversaturation or poor lighting can cause your eyes to become tired. Let's see how to make the necessary settings using a few simple tools.

How to change brightness on Windows 7 (or any other system) on a desktop computer

First, let's look at the moment the system starts. The user usually associates the normal mode of image perception with when the welcome screen appears on the monitor. Just by its appearance you can judge how comfortable it is perceived by the eyes. Both brightness and contrast immediately attract attention. Changing one of the parameters on desktop computers can be done quite simply.

It's no secret that in desktop PCs or workstations the system unit and monitor (or several) are used separately. Their design is such that there are one or two buttons directly on the front panel: increasing or decreasing brightness.

In addition, if, so to speak, in a question related to how to change the brightness of the screen or the contrast of what is displayed on the monitor, we dig a little deeper, it is worth noting that any monitor has its own menu, called up by a special button, in which there are advanced settings, including the mode of shifting the image, stretching or narrowing it, etc. As you can see, personalization is quite simple.

How to adjust screen brightness on a laptop

With laptops the situation is even simpler. Since the screen is an integral part of the entire design, there are no special buttons on it, as is provided for free-standing monitors. Nevertheless, the question of how to change brightness on Windows 7 or any other system (there is no fundamental difference) is solved using special keyboard shortcuts.

As a rule, changing the brightness parameter is done using the Fn button in combination with either function keys, which have up and down arrows and an image in the form of a sun. For example, on Fujitsu laptops these are the F7 (increase brightness) and F6 (decrease) keys, on others - F2 and F1, etc.

In some models, such settings can be made using the same pressed buttons using additionally standard right/left arrow buttons (sometimes up/down).

on any Windows system

Another simple method to solve the issue of how to change the brightness on Windows 7 is to right-click on an empty area of ​​the Desktop and select screen settings (personalization) from the context menu.

After entering the section, all available parameters will be displayed, which can be easily changed at your discretion.

Setting parameters in the power plan

These were, so to speak, the simplest methods. Now let's see how to adjust the screen brightness on Windows 7 using the system's own tools. To do this, you need to use the power section, which is accessed from the standard one. Here you need to select the option to change settings, after which two main plans will be shown (balanced and economy mode).

If for some reason the user is not satisfied with them, they can simply be changed. To do this, use the item for changing additional settings, where the adaptive mode is turned on. You can also change the brightness in the “Screen” section, where the settings are presented in the category of parameters for turning off the display.

Using a video card management program

How to change brightness on Windows 7 in another way? You can use special utilities for managing NVIDIA and AMD graphics adapters, which are initially installed on the system.

After calling the control program either from the system tray, if it is active, or from the same Control Panel, you need to find the display settings section in it, and then go to the Desktop color adjustment item (for NVIDIA, for example). It is here that you can change the brightness, contrast, gamma, image saturation, and much more.

The simplest comfort test

So, the screen parameters are set. Now you need to check how comfortable the perception will be. To do this, open a blank Word document. If you feel uncomfortable when looking at it, the screen settings should be changed. You can simply take a blank sheet of A4 paper and compare it with the white field of the document. If there is no difference when looking at both the sheet and the screen, then everything is in order. Finally, do not forget that when working at a computer or laptop for a long time, no matter how optimal the settings are, it is recommended to take a break of about a quarter of an hour every 45 minutes to relieve fatigue, including from the eyes.

As for the settings, the methods are quite varied, and which one to use is up to you. However, if we are talking only about brightness, the best option would be the and buttons. But if you need to make fine adjustments, it is better to use software from both the operating system itself and the programs included in the control software of graphic cards, especially since this is what they are designed for and calculated.
