    Instructions

    Promote brightness monitor can be done using the image settings buttons located on its front panel. Beyond management brightness yu images through the menu and the selection of the appropriate parameter, manufacturers usually program quick access to this function. To increase brightness monitor, press the button located on the front panel, which shows . It is this generally accepted symbol that is usually brightness.

    If this doesn't help and the picture is still darker than you want, use image adjustment software. To do this, go through the “Control Panel” to “Display Settings” and click the “Advanced” button. If you have installed video card drivers from the manufacturer or similar ones, then in the new settings window that opens you will see a tab with the name of the card model. If you don’t have one, then install the drivers, since using standard Windows programs you can increase brightness monitor it won't work.

    Going to the video card settings tab, select " Graphic characteristics"or a similar setting related to color adjustment. You will see “sliders” with which you can change brightness and image contrast. To do this, simply move them to a new position. As a rule, increase brightness monitor it happens right away.

    On old CRT monitor x dullness is its first sign of impending breakdown. Today, there is usually no point in repairing one like it was done before in the absence of alternatives and with high prices for equipment, since it is much easier to buy an analogue of it. And modern “thin” monitors are not very expensive. Therefore, if yours has begun to darken, it is better to take a closer look at the new models in stores computer equipment.

    • Adjusting the brightness, contrast and sharpness of the picture

    Sometimes it happens that the colors on the display become paler, the shades of colors are less distinguishable. Or you don’t like the brightness of the monitor, text is perceived poorly. Then you need to adjust the display brightness.

    You will need

    • - monitor.

    Instructions

    Settings are made using special calibration programs that are installed on personal computer With installation disk or downloaded from the Internet. These programs activate the image on the screen. They are connected to a special device temporarily attached to the front of the monitor. This device allows you to determine the brightness level. Then it automatically changes the settings. You do not need special drivers for your personal computer for this.

    You can manually adjust the monitor brightness. For this purpose, a number of buttons are provided on its front panel. By turning them on, you can adjust the brightness and contrast of the display. The buttons are labeled standard icons. They can be located on the side of the monitor. It is also worth noting that on newer monitor models the buttons may be touch sensitive, so be careful not to accidentally press any button with your fingers.

    Click the contrast adjustment button. The settings window will open. Click on plus or minus to select the contrast that suits you. Save your settings and disable this window. You can make these adjustments several times in a row to compare the brightness position on the screen in all cases. As a rule, each user chooses the most optimal option for himself.

    Now you can start adjusting the brightness. Just as in the previous case, click on the button to adjust the display brightness. In the window that appears, again, moving towards plus or minus, set the brightness you need. Save the settings again and close the window. The display brightness is adjusted. It is worth noting that the settings made using special program calibration, better than manual tuning.

    Quite often the image on the monitor screen is darkened for various reasons. At the same time, it is impossible to correct the image in a video file, in a photograph, and on a regular desktop using one setting. But in all of the above situations it is quite easy to increase brightness images separately.

    Instructions

    To increase brightness in a static image, for example, open it with a viewer program. Standard programs Windows are not suitable for this: they do not even have functions for this simple editing. However, if you wish, you will find quite a few other programs of this kind on the Internet: ACDSee, FastStone Image, IrfanView are the most common and far from the only ones in their class. Depending on the selected program, the menu items and names will differ, but in general the order of your actions to increase brightness, will correspond to the following diagram. Using the IrfanView program as an example: select the Color corrections item in the Image menu and in the window that appears, move the Brightness parameter slider as far as necessary. Then click OK and resave the image if desired.

    To increase brightness when producing , examine available settings output in your player. Menu items and settings vary in all players. In general, you need to find the video output settings, which can be located both in the “Settings/Tools” menu and in the “Video” sub-item. Using VLC-player as an example, to increase brightness, go to the “Tools” menu and select Extended Settings... In the window that appears, go to the “Video Effects” tab, check the “Image Settings” box and use the brightness slider to set new display parameters.

    If you are not satisfied with the overall image on, and not the quality separate files, and the settings on do not help, then you can increase brightness using the settings itself. To do this, through the Control Panel, go to Display Settings and click the “Advanced” button. Next (using the example of a video card Intel Graphics) go to the settings tab of the video card parameters from the manufacturer. Then select “Graphic” - “Color Settings”. You will see the brightness parameter slider, already familiar from the previous steps. Move it and click on "OK".

    Properly adjusted PC monitor parameters, such as brightness, contrast and others, can significantly improve perception graphic information. And if everything is clear with setting, say, contrast with desktop PC monitors (the buttons for adjusting monitor parameters are located on the monitor itself), with laptops and netbooks things are more complicated.

    Instructions

    Most laptop keyboards have display settings buttons, but they only affect brightness. You can change the contrast in the driver settings of the video card installed on your video card.

    In the case of a video card from manufacturer Nvidia The contrast is adjusted using the video driver control panel. Right-click or on the desktop, and then select the item called "Panel Nvidia control».

    Go to the menu item “Adjust desktop color settings” using the link on the left side of the window. Then select “Use Nvidia settings” and increase the contrast in the corresponding item using the slider to the required level.

    In the case of a card from the manufacturer ATI, first download it from the Internet latest version Catalyst video driver. Functions in in this case Similar to Nvidia Control Panel functions. Go to the Color tab located on the left side of the program window. Now you can adjust the contrast in the corresponding item (Contrast) using the slider. Once you've finished adjusting the contrast, save your changes.

    If yours is equipped with a built-in Intel Graphics card, in the video driver settings, select the item called “Graphics characteristics”, and then “Color settings”. Here (again, using the slider) you can adjust the contrast to your liking.

    If you need to increase the contrast directly during individual pictures or videos and films, use the functions of the application with which you view a particular file. For example, in the VLC player, access to the contrast settings is as follows: left-click or touchpad on the “Tools” item and select the Extended Settings sub-item. In many programs, contrast can be adjusted by going through a chain of menu items: “Options” -> “Image settings” (or “Display settings”).

    Be careful when changing video card parameters, consider its performance.

    Useful advice

    Assign a command to the keyboard buttons to change the brightness of the monitor using a special program.

    When changing power modes, the screen brightness changes. If, when operating from mains power, the monitor backlight is turned on at almost maximum power, battery operation requires saving, so the brightness is less.

    Question from a user

    Hello. The brightness on my laptop began to change spontaneously: when the image is dark, the brightness drops, and when it is light, it is restored to its normal level.

    How can I get rid of this problem, otherwise my eyes are starting to get tired because of it? OS: Windows 8, graph. accelerator (video card) Intel HD 4000 (built-in).

    Good day!

    This problem began to appear more and more often after the release of Windows 8 (this OS introduced the ability to adaptively adjust the brightness, depending on the picture on your screen). Also, some laptops are equipped with special software and sensors that determine the level of illumination in the room and, based on it, adjust the brightness of the screen.

    There's nothing wrong with that, but certain cases such a change does not allow it to work normally and interferes with the user. In the article I will tell you in detail how you can disable this spontaneous change in brightness...

    Eliminate automatic monitor brightness changes

    1) Disable adaptive brightness control

    This is the first thing to do. This option is available in Windows 8, 8.1, 10. Those who have Windows 7 can omit this part of the article.

    You need to open the power settings section:

    1. or via the following address: Control Panel\Hardware and Sound\Power Options
    2. or by pressing the Win+R keys and entering the command powercfg.cpl (see screenshot below).

    In power settings: follow the link "Setting up the power plan" in the selected mode (on the screen below - this is balanced mode. The selected mode is marked in bold black).

    Now find the tab among the settings "Screen" and open it. Here in the tab there are 3 key settings:

    1. screen brightness from battery and network: set the values ​​that suit you;
    2. screen brightness level in dim mode: set exactly the same values ​​that you have specified in the tab "Screen brightness";
    3. turn off adaptive brightness control from mains and battery (see screenshot below).

    Now save the settings and try to look at light and dark pictures (for example) to evaluate whether the brightness changes. As a rule, such settings completely eliminate this problem...

    Update 06/10/2018

    If you are using Windows 10, pay attention to its control panel (to go to it, press Win+i). In the section "System/Display" there is a special a setting that allows the laptop to change brightness as the ambient light changes. Turn it off too!

    2) Setting up the power supply for the video card

    The laptop itself can reduce the brightness when certain modes work. For example, IntelHD video cards support display energy-saving technology and extended runtime in games when running on battery power. Similar technologies are available in both AMD and nVidia.

    First you need to go to the settings of the video card driver (you can do it through - see the screenshot below), or you can do it through the tray icon, next to the clock.

    Settings Intel graphics(trey)

    Important!

    If you do not have a tray icon, and there is also no link to graphics settings in the control panel, most likely you do not have the drivers installed (it is likely that you have a “universal” driver that was installed when Windows installations). In this case, I recommend programs for updating drivers:

    They need to set the following:

    1. set the energy saving parameter to maximum performance mode;
    2. disable extended runtime for games on battery power;
    3. disable the display energy saving technology (screen below - see arrows).

    Note!

    For example, in video cards from AMD - you need to open the "Power" section, then turn on maximum performance, and disable Vari-Bright technology (this is AMD technology that allows you to adjust the brightness).

    Vari-Bright disabled! (settings AMD Graphics) / Clickable

    3) Sensor monitoring service

    There is one service in Windows that monitors sensors and adjusts the display lighting, depending on the lighting of the room in which your device is operating.

    I can say that sometimes the service does not work correctly and can affect the brightness adjustment, even if you do not have any sensors!

    How to disable sensor monitoring services

    Open a window with services: the easiest way is to press keys Win+R, enter services.msc, press Enter. The method works in all versions of Windows.

    Next in the list you need to find the service "Sensor Monitoring Service" , open it. In the column "startup type" set [disabled], and stop the service itself, so that the status appears as "Stopped" (see screenshot below).

    Then save the settings and restart the laptop.

    4) Laptop control center

    Certain laptop models have a control center among the software installed along with the drivers. For example, in the line of VAIO laptops from SONY there is VAIO control center .

    In this control center, for example, you first need to open the tab "Power supply" and exhibit high performance, and also disable the function that extends battery life (see screenshot below).

    High Performance // Power // VAIO Control Center

    Image Quality // VAIO Control Center

    Actually, it is hardly possible to give a description for each of these centers. The VAIO Center is shown above as an example of such software.

    There is also something similar in Lenovo laptops: various night modes, dynamic changes in brightness, contrast and other things can significantly change the quality of the picture on the screen. It is recommended to disable them all (at least at the time of setup and adjustment).

    5) Problems with hardware

    A change in screen brightness may be due not only to software settings, but also with faulty hardware. In what cases can you determine that the laptop hardware is to blame:

    • if not only the brightness has changed on the screen, but also stripes, ripples, and dots began to run (as in the example below);
    • if when you increase/decrease the brightness on the monitor, absolutely nothing happens;
    • if the brightness changes even without changing the picture on the screen and without changing the lighting conditions in the room;
    • if the brightness is in different parts screen is different.

    Help!

    If you have stripes and ripples displayed on your monitor, I recommend that you read my other article:

    Stripes and ripples on the screen / As an example

    Happy work!

    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. Change one of the parameters to desktop computers It can be quite elementary.

    It's no secret that exactly in desktop PCs or workstations system unit and the 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 separately 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 contain up and down arrows and an image in the form of a sun. For example, in Fujitsu laptops These are the keys F7 (increase brightness) and F6 (decrease), 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 resolve the issue of how to change brightness on Windows 7 is to right-click on empty space Desktop and out context menu select screen settings (personalization).

    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 item 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 change point 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 management graphics adapters NVIDIA and AMD, which are initially installed on the system.

    After the call control program either from the system tray, if it is active, or from the same Control Panel, in it you need to find the display settings section, 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 an empty Word document. If you feel uncomfortable when looking at it, the screen settings should be changed. You can just take blank slate 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, don't forget that when long work at a computer or laptop, no matter how optimal set parameters, every 45 minutes it is recommended to take a break for about a quarter of an hour 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 buttons will become and But if you need to produce fine tuning, it is better to apply software both the operating system itself and the programs included in the control software graphic cards, especially since this is exactly what they are designed for.

    Everyone knows that it works poorly in low light. Therefore, it needs to be added. Let's look at several options for how to increase screen brightness on a Samsung, Acer, Dell, HP, Sony, Asus laptop. operating systems windows 7, 8, xp and vista.

    It should be noted right away that there is a difference between XP and the rest. Developers began to look at ease of use, starting with Vista, including increasing screen brightness. In more earlier versions more emphasis was placed on stability.

    But as for laptop models: samsung, acer, dell, hp, sony or asus, there is practically no difference with (meaning increase the screen brightness, there is practically no).

    Let us first consider the simplest and quick way How to increase the brightness on a laptop screen.

    To do this, we will use a keyboard shortcut. The first FN (usually the inscription is blue and located at the very bottom on the left side). The second F6 is what increases screen brightness on laptops, while F5 decreases it.

    100% assert that this is exactly what will happen at all Samsung models, acer, dell, hp, sony, asus - I won’t, but if there are some changes, they won’t be significant. For convenience, icons are drawn on the keys. Solid sun - darken the brightness, with a gap inside - increase it.

    If for some reason you cannot increase the brightness on the screen of your laptop (Samsung, acer, dell, hp, sony, asus) using the method described above, then open , find the “screen” option there and click on brightness settings on the left side.

    Then at the very bottom you will see a slider (as in the picture below), move it to the right side, thereby increasing the brightness of your laptop screen.

    There are indeed cases when increasing the screen brightness may not work. This does not concern software, but the physical components of the laptop. For example, the monitor lighting lamp has burned out or the screen itself has sagged.

    Although this happens quite rarely, it is not impossible. As for lighting lamps, they cost about $100, and the screen very rarely sags.

    I am currently writing on a laptop that is 8 years old and have not yet noticed any deviations in the brightness of the screen, although it sometimes works for three days without turning off.

    In general, the video card is responsible for screen brightness. If you open its settings, you can also increase the brightness. One more thing.


    Everything is controlled (executed by commands) by the drivers, therefore, if something does not work, you should look at them and possibly update them.

    So for example if you have ASUS laptop, then take a closer look at the ATK Hotkey utilities for brightness; if they are not there, download and install them.

    This article, of course, describes only general (universal) ways to increase screen brightness on samsung laptops, acer, dell, hp, sony, asus.

    Of course, you may have “individual” problems. Then write in the comments and we’ll decide. Good luck.
