Where the brightness of the computer screen is adjusted. How do I adjust the brightness on my laptop? Pros and cons of function keys when adjusting laptop screen brightness

A user who recently purchased a laptop may encounter an issue with adjusting the brightness. In saving mode, the screen is too dark, when connected to the network, on the contrary, it becomes too bright, which interferes with normal operation. If you have not yet figured out how to increase and decrease the brightness on a laptop, then our material will help you set it up.

The main method is setting via Control Panel... It is suitable for all modern versions of the Windows operating system. To do this, go to the menu Start(Start) and select on the right side of the window Control Panel... Here we will see a list of services, we need to go to the menu Power supply.

If you do not see it, then set the display of all the icons - in the address bar, click on the tab and select Show all panel items... Also, the section with power supply can be found through the search bar. Here we will see the current laptop mode and brightness. To increase the parameter, you need to move the slider to the right, and to decrease, respectively, move it to the left.

Is the slider active? There can be two reasons for this defect:

• It is necessary to install drivers for the laptop screen - usually they are installed automatically, but if you installed a new version of the OS, then the drivers could crash. Just go to the website of your laptop manufacturer, select your model, and then click the button Download opposite the graphics drivers.
• The laptop does not provide brightness control. Such models are extremely rare, they belong to the budget class. Nothing can be changed here.

Changing brightness using keyboard shortcuts on a laptop

We will not say exactly which keys are responsible for adjusting this parameter. For example, on netbooks, this may be the arrows next to the Enter key. Also check F1-F12. You need to find the key with the image of the sun - on one button it will be crossed out (decrease in brightness), and on the other it will be luminous (increase).

ATTENTION! If you just press this key, then nothing will happen - the brightness will remain the same. All operations with keyboard buttons are performed by holding down the Fn key. You will find it next to Ctrl and Win.

Hold Fn and press the brightness change key. Do not release Fn while you are changing the parameter. This also applies to changes in the volume level. Hotkeys are easier to work with - you don't need to go into power settings. This is especially useful for video games and watching videos.

Adjusting brightness in Windows 7 by mode

There are three operating modes for a laptop:

1. Saving ... The mode is designed for the maximum long-term use of the computer - the hardware works slowly, but for a long time. The brightness in this mode is usually at a minimum. The laptop automatically goes into economy when disconnected from the charger.
2. Performance ... Here, the opposite is true - the use of all resources and maximum performance. If you want to try out a new video game, then it is better to choose this particular mode. In some models, it is activated automatically when connected to the network.
3. Balanced ... Ideal for working with your computer when it is disconnected from the network. The laptop is fast, but it also saves battery power by lowering the screen brightness.

Modes can be set and configured in the menu Power supply... In addition to brightness, here you can set the reaction to closing the laptop lid, prolonged inactivity, etc.

You can also change modes from Taskbars in the lower right corner (where the time and language are indicated). Click on the tab to display the rest of the icons. You need to click on the battery icon - menu Power supply displayed in the same way in Windows 7, and in the top ten. You will see a compact window where you can select Savings, Balance or Performance.

Attention! If you set the high performance mode for a laptop that is disconnected from the network, then it will be discharged in 1-2 hours. Keep track of the charge in the taskbar - the battery icon shows how many hours of operation are left.

We recommend that you immediately set the brightness at a certain level for each mode. To do this, you need to go to settings Power supply... Now select each mode in turn, fix the brightness slider at the desired level, and then press the button Apply... You can also make settings for the laptop lid right away. For example, you can remove the automatic shutdown when the lid is closed. If necessary, you can change the brightness level in any mode using the appropriate keys.

Brightness adjustment programs

For those who prefer a more precise adjustment of the brightness parameter, it is recommended to download a special software. For example, you can take the Monitor Plus utility - download link. If in the standard Windows tool we are offered to change on a scale where one division is about 10%, then the Monitor Plus utility provides a scale with divisions from 1 to 100. This is an excellent solution for people with sensitive vision who find it difficult to find the appropriate brightness in the standard menu power supply.

There is another software for changing the brightness (My Monitor, Display Tuner), but the Monitor Plus utility stands out for its simplicity and small size. Download it, start the installation, after that the setup window will open immediately - even a novice user can work with Monitor Plus.

What to do if the brightness does not change: 2 video methods

This video shows you how to change the brightness on a laptop in two ways. Use this simple instruction if you were unable to adjust the brightness using the above tools:

As you can see, adjusting the brightness is quite simple. Usually, users do not waste time changing modes, but simply use hotkeys. Our instructions are suitable for any laptop model. This also applies to OS Windows versions.

The easiest way to change the display settings on your home PC is with the control buttons on the monitor itself. The same buttons, depending on the monitor model, will help you change the contrast, color rendition, calibrate the screen position, and create different modes. However, there are many cases where hardware customization is not available, because some monitors are assembled without function buttons for aesthetic purposes. And the owners of laptops and netbooks are completely deprived of such an opportunity. Therefore, there is also a software adjustment of the screen brightness using standard Windows 7 tools or using third-party programs.

Change brightness using Windows 7

This item is only suitable for laptop owners. Operating systems installed on a personal computer, as a rule, do not have such functionality.

Open the "start" menu, then "control panel" in the menu on the right. If your windows system is set to view in the form of categories - you need to go to "hardware and sound", subcategory "power supply". If the view in the form of icons is set, then at the very bottom of the list, find the "power supply" icon and open the corresponding section.

In the window of work with power supply select the item "setting off the display". Next, go to the power plan settings. One of the available sliders - just makes it possible to change the brightness of the screen.

In addition, there is another special way to adjust the brightness of the monitor on a laptop. To do this, you need to hold down the special function key FN and right / left arrows. For some laptop models, instead of the arrows, you must hold down the keys with the sun icon. These steps are also valid for Windows 8.

Changing brightness using the video driver

This item will suit any user. To complete the settings, you need to go to the video card control panel.

Go to the "start" menu, then to the "control panel" in the menu on the right. If your windows system has viewing in the form of categories, you need to open "design and personalization", subcategory "NVidia control panel" (if you have NVidia hardware) or "AMD" (if the manufacturer is AMD). If the view in the form of icons is set, find the same icon and go to the corresponding section.

Parameters such as the brightness and contrast of the monitor or display are paramount when choosing a laptop. If they are accompanied by excellent characteristics, then this is conducive to comfortable reading, quick performance of all assigned tasks.

Laptop brightness and contrast are very easy to adjust

Otherwise, very rapid eye fatigue occurs, cramps, lacrimation and other undesirable consequences appear. However, you can adjust the brightness of your monitor yourself using some good advice from an experienced user on how to adjust the brightness of your monitor.

There are several options for solving this problem. Moreover, each option is available for understanding the sequence of actions and is unlikely to provoke additional questions from you related to misunderstanding of individual steps.

In general, all, even outdated notebook models, are set to average values ​​of such parameters.

In addition, you may face a situation where your modern laptop will be able to independently adjust the brightness and contrast settings.

Indeed, modern manufacturers equip some computer units with such functionality. In this case, when the illumination in the room space increases, the brightness on the laptop is automatically reduced. In the same way, on the contrary, when the illumination is reduced, the laptop is able to increase the brightness itself to provide the user with a comfortable working environment, even for a long time.

If you are not the owner of such modern technology, but are content with slightly outdated samples that are not accompanied by such functions, you can still intervene in the process of adjusting the brightness and contrast, providing yourself with conditions under which the eyes will not experience stress.

Before proceeding to directly study the recommendations on how to increase the brightness of the monitor, each user must understand that such a setting directly affects the state of charge of the battery.

The higher the brightness, the faster the laptop will discharge.

The higher the brightness, the faster the battery will discharge. In this regard, being outside the reach of recharging the laptop from the mains, on the contrary, it is recommended to reduce the brightness and contrast settings.

OS correction

In particular, the brightness and contrast of the monitor can be adjusted by simultaneously pressing two buttons, one of which is Fn. This button is in most cases located at the bottom of the keyboard.

The second button on different models may be different, but its main reference point is, in addition to the main inscription, the presence of an icon with the image of the sun.

It is important to understand that there should be two buttons with the image of the sun. One aims to increase the brightness, and the second helps to reduce it.

Sun buttons let you adjust brightness

Often these additional buttons are arrow keys, which are located between the main keyboard and the numeric keyboard.

Having used such methods at least once, it will become clear to you not only how to reduce the brightness of the monitor, but also that such actions are not accompanied by difficulties.

Setting up the video card

If your device has an NVidia graphics card, just right-click on an empty space on the desktop. In the context menu that opens, go to the "NVidia Control Panel" option.

Now in the new window on the left side you will be able to see many different options, you need to go to "Adjust Desktop Color Options".

The second point of the proposed settings will be the proposal to choose a method for adjusting the color.

Find the item "Use NVidia settings", put a mark next to it. After that, the settings for brightness, contrast, gamma will become active, you can again move the slider, choosing the optimal parameters for yourself.

If your laptop does not have an NVidia video card, but a Radeon, you need to download a special Catalyst application, which is endowed with the same functionality.

By the way, on the net you can easily find and download to your laptop many different interesting applications that help you choose the optimal settings. In particular, NTest is one such application.

So, after reading these recommendations, each user, regardless of his practical experience with a laptop, will be able to adjust the display so as to favor comfortable work that does not provoke fatigue, watery eyes and other undesirable consequences.

To improve results display brightness and contrast settings, use the Display Color Calibration Wizard (The Display Color Calibration Wizard will help you adjust these and other color settings). The procedure for adjusting brightness and contrast depends on the characteristics of the display.

Brightness and contrast controls for some monitors are located on the front panel.

• OSD menu... The brightness and contrast settings of some displays can be adjusted using the OSD menu, and then the brightness and contrast can be set in the final menu. You can usually view the OSD by pressing a button, possibly called “Menu,” located on the front of the monitor.
• Laptop display... Notebook displays do not have front panel brightness and contrast buttons. Most laptops do not have a contrast control. However, the brightness of many laptops can be adjusted by holding down the Fn key and pressing the corresponding function key to decrease or increase the brightness. When using the Display Color Calibration Wizard on a laptop, set the display brightness to maximum.

For more information on adjusting display brightness and contrast, see the monitor documentation or manufacturer's website.

Automatic brightness adjustment by adaptation

Adaptive brightness Is a Windows feature that uses a light sensor to automatically adjust the display brightness to match the lighting conditions on your computer. To use this feature, light sensors must be installed and turned on on your computer.

To determine if your laptop or computer monitor supports adaptive brightness, look in the Power Options window. Enable adaptive brightness or view your computer's documentation.

Adaptive brightness triggering

1. Open the Power Options window.
2. On any meal plan, click Set up a plan.
3. Click the button Change advanced power settings.
4. In the list, expand the section Display and expand the section Enable adaptive brightness.

A laptop display uses more power than other components, therefore lowering the brightness will help extend battery life, and a dim or bright display can cause eye discomfort when working on a PC. To make your work more comfortable, consider how to adjust the brightness of the screen on a laptop in Windows 7, 8, 10.

Laptop models are different, so the brightness setting may differ from the recommendations outlined in the article. The material describes the general steps applicable to manufacturers such as Acer, Asus, Hp, Samsung, Lenovo and others. There are enough ways to change the screen brightness, both standard and using third-party software. Let's take a closer look at all the methods.

Modern laptop models support changing the screen brightness with a keyboard shortcut, which greatly facilitates this process. You must hold down the Fn function button (located at the bottom of the keyboard near the left Ctrl,), then press the up or right arrow keys to increase the brightness, down or left to decrease it. The keys F1 through F12 can also be used in combination with Fn.

All combinations depend on the model, the most common are shown above. Typically, buttons used with Fn have a symbol that resembles the sun. The picture below shows the keyboard of an Acer laptop, where Fn + right arrow will brighten the screen, Fn + left arrow will dim. If you can't find the sun symbol on your keyboard, check your laptop manual to see if there are hotkeys assigned to it to change the brightness.

Changing brightness through power settings

If a combination of buttons is not assigned to your PC, or you need to fine-tune the brightness of the screen on a laptop in Windows 7, 8, 10, use the power options. Click on the battery status icon in the tray, then click on the link "adjust screen brightness".

If there is no battery status icon in the tray, then select the "small icons" view. Find "power supply" among the items, click it.

At the bottom of the window, move the slider to a comfortable position. Changes are applied and saved immediately.

To make a detailed adjustment of the screen brightness in Windows 7, 8, 10, click on the "setting up a power plan" link opposite the selected plan (see the screenshot above). Move the sliders to set the brightness of the plan for battery and mains mode. I also recommend it to save energy. Be sure to click the "save changes" button.

You can also change the brightness of the screen on a laptop by clicking on the link for additional power settings (see the picture above). Expand Screen, then Screen Brightness. Then select "from the network", "from battery" and set the percentage. Would recommend yet. After the changes, click OK.

Additional ways to change brightness

Go to Control Panel, select Large Icons View, locate Windows Mobility Center. In the seven, you can quickly launch it by pressing the Win + X key combination. Then you just need to move the slider to the desired side.

You can adjust the brightness of the laptop screen in Windows 8 through the settings panel. To call it, press Win + I. Next, click the brightness icon and adjust the slider. To call up similar settings in Windows 10, click the action center on and adjust the settings.

1. iBrightnessTray
2. Display-Tuner
3. Display Resolution Manager
4. A lot others

As an example, consider a simple iBrightnessTray program that does not require installation. Download the archive with the application, unpack it to a convenient place. Then launch it, after which the iBrightnessTray icon will appear in the tray. Often the icon falls into the area of ​​hidden icons, so you need to bring the iBrightnessTray icon to a visible place on the taskbar (see the picture below).

Press the right button on the icon to open the menu, check Auto Start so that the program will automatically start when the laptop is turned on. The Change Screen Saver function calls the screen saver change window, Exit turns off iBrightnessTray, the rest of the functions are described above.
