How to make your laptop screen brighter

Setting by standard means

Laptop computers provide for the use of hot keys, with which you can quickly make adjustments to certain parameters. For example, with one click, you can completely mute the sound or turn off the built-in microphone. The same goes for adjusting brightness.

By default, Microsoft OS includes an auto-adjust feature for notebook computers. Disable auto brightness and set up a power plan as follows:

  • Open “Control Panel”.
  • Then go to the subsection “Hardware and Sound”.
  • Now open the subsection “Power supply”.
  • Opposite the name of the power scheme, click on the settings button.
  • Here you need to go to additional power options.
  • In the list, find the item “Display”. “Enable adaptive brightness control” and set it to “Off”, then close the window with saving changes.

Now you need to increase the brightness level for all power plans. Select one of them and click on the button marked in the screenshot:

Drag the slider to the right position for the computer to work when disconnected from the mains and do the same with the setting for the laptop when connected to the charger. After that click on “Save changes”.

Now you know how to disable adaptive adjustment and how to change the brightness on a laptop with Windows 10 (x32-bit or x64-bit) OS of any version. Unfortunately, you will not find such parameters on a desktop computer, so you will have to use other methods.

Keyboard shortcuts and buttons on the monitor

It remains to disassemble the last method of decreasing or increasing brightness, which refers more to the hardware method, rather than specifically to Windows 10.

Laptops have separate system keys (in most cases Fn), which, in combination with others, allow you to make adjustments to darken or lighten the image on the screen (as well as change the sound level, lock the keyboard, turn off the screen, and so on). You can see the required combination in the documentation for your device or on the official website.

What if these keys don’t work? Most likely, you have not installed the official software from the manufacturer. This happens when you reinstall the operating system yourself. Find the software package on the manufacturer’s website and install it.

For a stationary PC, you do not need special software or a driver. the brightness will be decreased or increased using the mechanical keys on the monitor case. Changing parameters is OS independent.

We’ve figured out how to change the low or high brightness level in different ways, which differ depending on your device. Each of the methods has been tested in practice. If you failed to change the display settings in one of the ways, then go to another.

All methods of changing brightness

You can adjust the required brightness level of the image on the computer or laptop screen in the following ways:

  • standard Windows 10 settings;
  • by third-party means;
  • video card settings;
  • via hot keys;
  • through monitor settings.

Depending on whether you are using a desktop computer or a laptop, you will have access to the adaptive adjustment function, which we will also talk about in more detail.

How to increase or decrease brightness on Windows 10 PC

With correctly selected brightness, contrast and other parameters, the user will be able to spend a long time comfortably at the PC. Let’s see how to increase screen brightness on Windows 10 in different ways.

How to adjust parameters through the video card driver

Depending on which video card you are using, the following tools are available to you to manually increase or decrease the brightness:

  • AMD Control Panel for video cards from AMD;
  • NVIDIA Control Panel for NVIDIA GPUs;
  • Intel Graphics Options for Intel Integrated Graphics.

All presented tools are installed together with the driver and differ little from each other in terms of interface and management. Let’s take a look at the settings using an example of how to work with the NVIDIA Control Panel:

  • Right-click on the desktop to enter the NVIDIA Control Panel via the context menu.
  • With this tool you can change the parameters separately for video playback in the player and for the entire display. In the “Video” section, select the first tab (1). Now select “With NVIDIA settings” to unlock access to the sliders (2). With their help, you can reduce or add brightness, contrast, saturation and hue exclusively for the picture in the video player. To return to automatic mode, switch the option to “With video player settings” (3).

Now you need to disable automatic selection of parameters for the display itself. To do this, you need to do the following:

  • Open the “Display” tab and go to the marked subsection.
  • Now select the second item to unlock manual value changes. Brightness, contrast and gamma are also available here. Try decreasing or adding one of the values ​​and watch how the picture changes on the screen. Also you can change the presented parameters for a separate color channel (RGB).
  • To save all changes, click on “Apply” and close the window.

In this way, you can raise or lower the brightness through the capabilities of the video card and driver. If the parameters change, auto brightness turns on by itself, then the problem lies in the driver malfunction. To update it you need:

  • Open “Device Manager” through search or in any other way.
  • Then go to the subsection “Video adapters” and select your video card.
  • Right-click on it and click on “Update Driver”.
  • To save a lot of effort, you can choose to update automatically (1). If you downloaded the driver distribution package from the official website in advance, then select “Search for drivers on this computer” (2).
  • Specify the folder with the driver and click “Next”.
  • After installation, be sure to restart your computer.
make, laptop, screen, brighter

Third party program

If the Microsoft operating system does not allow you to change the image settings on a desktop PC, then use the third-party iBrtightness Tray or Display Tuner utility. You can find them yourself in the public domain on the Internet.

Let’s look at the example of the Display Tuner application. Once launched, you will see the following window with sliders:

With it, you can adjust not only the brightness (1), but all other parameters. contrast (2), colors (3).

The second tab “Geometry” contains settings for changing the position of the image on the monitor.

Also, using Display Tuner, you can adjust the sound level of audio tracks and video playback.

In the “Profile” tab you can create your own profile and save it. Thereafter, the picture settings will not change automatically. To enable a profile, you can use hotkeys (you can change them).

If you have any difficulties, then check out the visual instructions in the video. It covers all the methods from this article.

Everyone knows that it works poorly in low light conditions. Therefore, it needs to be added. Let’s consider several options on how to increase the screen brightness on a samsung, acer, dell, HP, sony, asus laptop in windows 7, 8, xp and vista operating systems.

It should be noted right away that there is a difference between XP and the rest. The developers began to look at the convenience of work starting from whist, including increasing the brightness of the screen. Earlier versions focused more on stability.

But as for laptop models: samsung, acer, dell, HP, sony or asus, the difference with the brightness settings (I mean increasing the screen brightness, there is practically no).

Let’s first consider the easiest and fastest way to increase brightness on a laptop screen.

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

I will not say 100% that this will happen on all models of samsung, acer, dell, HP, sony, asus, but if there are some changes, they will not be significant. For convenience, icons are drawn on the keys. Solid sun. darken the brightness, with a gap inside. add.

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 cases when it may not be possible to increase the brightness of the screen. This is not about the software, but about the physical components of the laptop. For example, the monitor lighting lamp burned out or the screen itself sank.

Although this happens quite rarely, it is possible. As for lighting lamps, they cost about 100, and the screen “sags” very rarely.

I am now writing on a laptop, which 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 the brightness of the screen. If you open its settings, then the brightness can also be increased. One more moment.

Everything is led (executed by commands) by drivers, therefore if something does not work on them you should look, it is possible to update.

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

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

Thank you, Yaroslav Ivanishyn, now I know how to change the brightness of the laptop

Hello. I read your article and did everything as described. Nothing helps. I have a CLEVO M570TU, when the battery is charged at 10%, it lowers the brightness. The buttons do not respond, the brightness slider in the Power Control Panel has disappeared altogether for a long time. I tried to update the drivers, the system says it is not required. I have Windows 7 Ultimate. Tell me, what can you do.

When operating on battery power, the system automatically enters power saving mode. To change this, enter the control panel, click on “power supply”. There you will see two modes: balancing and energy saving.

Opposite each of them there is a line “setting the power plan”. click. A new window will open for you. In it, some changes can be made, but to adjust the brightness and so on completely for yourself, click below on: “change additional power settings”.

I couldn’t think of anything smarter how to reboot the laptop but did not help (((The hieroglyphs were gone but the colors remained dull, I know that it would have been better not to touch, but there was no one to help. I added brightness on the FN F6 keys, but it still didn’t help much. The main thing when the laptop is just loaded, the colors are good. How to fix prompt these “sudden” settings?

Maria. what operating system is installed and the name of the PC?

On Windows 10

You can increase or decrease the brightness of the monitor using the function keys and the “Mobility Center”, as well as “Windows Settings” and the slightly modified and available in all versions of the utility “Power supply”.

To adjust the brightness in Windows Settings, you will need:

  • Open the “Start” menu and click on the “gear” located in the leftmost panel.
  • By moving the slider in the “Display” section, select the optimal mode; no additional manipulations are required.

Power Settings

If a laptop or computer gives too much light and you want to turn down the brightness (or, conversely, you need to change the parameter upwards), and the owner of the device does not want to use the two methods presented above, you can try another one. Applying it is as easy as changing the screen scale; the main thing is to follow the given sequence of actions.

To set up an overly bright or dark screen on Windows 7, do the following:

  • Open the “Start” menu and select “Control Panel” on the right side of it.
  • In the window that opens, go to the “System and Security” section.
  • Or, if the “Icons” display option is selected, just “System”.
  • Further. in the subsection “Power supply”.
  • Select your mode and go to the “Power plan settings” button next to it.

Here the user can, by moving the slider, select the optimal screen brightness option. the procedure is SIMilar to that described above and does not need additional comments.

On Windows 7

There are three SIMple ways to add or remove the brightness of the laptop screen on Windows 7; all of them are completely safe for the device and can be mastered literally within a couple of minutes. or even faster.

How to increase / decrease the screen brightness on a laptop?

The user of the operating system from Microsoft has many interesting tasks: find and install the best free antivirus for Windows 7, learn how to get rid of system junk, find a site with the most beautiful desktop wallpapers, and so on. One of the most pressing issues is figuring out how to increase or decrease the brightness of a laptop monitor. The SIMplest ways to adjust this parameter are described below.

Function Keys

The fastest way, which does not require a laptop user on Windows 7 (as well as 8, 8.1 and 10), absolutely no additional knowledge and skills, a way to decrease or increase the brightness of the monitor is to use special keys.

You can change the brightness of the monitor using the keys, depending on the settings of the machine, in two ways:

  • SIMultaneously holding down the Fn and F2 / F3, F7 / F8 or others buttons on which the corresponding icons are applied. they will be discussed below;
  • by pressing only the corresponding keys without using the “function”.

This is no more difficult than flipping the image on a laptop; So, if the computer screen is too light or, on the contrary, the brightness is low for normal operation, the user should:

  • To decrease the brightness. press the button with a smaller “sun”, “light” or other icon with an arrow pointing down.
  • To add. use the neighboring one, respectively, with a large “sun”.
  • You can make sure that the changes have taken effect both with the help of your own organs of vision, and by the indicator of the current brightness that appears on the screen.
  • It is important to remember that it will not work to make the brightness lower than the minimum or higher than the maximum specified by the manufacturer. the indicator scale will be empty or full, and the user cannot change the factory settings using standard means.

Windows Mobility Center

A little more action will require a user who wants to decrease or increase the brightness of the laptop screen on Windows 7, the second method will be required, which is associated with launching a service utility.

To configure a monitor parameter without using the function keys, you should:

  • Open the “Start” menu by clicking the left mouse button on the checkbox located in the lower left corner.
  • Go to the folder “All programs”.
  • Further. in “Standard”.
  • And from here launch the Windows Mobility Center application.
  • In the window that opens, the user can, by moving the slider, adjust the screen brightness, and then proceed with further system settings. for example, free up space on the C drive.

On Windows 8

Adjusting the screen brightness on Windows 8 / 8.1 is done using keyboard shortcuts and in the order inherited from Windows 10; it will be discussed in the next section.

Summing up

There are several ways to increase or decrease the brightness on a laptop running Windows 7, 8 / 8.1, or 10. The easiest is with the function keys. The rest involve working with system options: “Windows Settings”, “Mobility Center” or “Power Supply”.

How to decrease or increase brightness on a laptop

The display brightness on a laptop is not constant. It can be either increased or decreased. And there are at least three ways to do it. In addition, there is a special free program that will regulate it itself depending on the time of day.

The easiest way to change brightness on a laptop is with keyboard buttons.

Typically, the keyboard of any laptop has two keys that regulate it. Most often these are F5 and F6 (located at the top), home and end (located on the right), or arrow buttons (left, right). But there may be other options. They are usually marked with a sun icon or an asterisk. Press them together with the Fn key (below).

For example, I have a keyboard where the backlight is controlled via F5 and F6. So, in order to reduce it, I press the Fn key and, without releasing it, F5. If you need to do even less. again F5. Then I let go of Fn.

And if you need to increase it on the contrary, then I do the same, only with the F6 key.

But it also happens that these keys do not work. That is, you press Fn and, without releasing it, the button with the “sun”, but nothing changes. This is usually due to drivers or BIOS settings.

Method 2

Right-click on the power icon and select “Windows Mobility Center”.

It can also be opened through “Start”. To do this, print or copy / paste into the search bar (Find programs and files) six English letters mblctr or windows mobility center

In the window that appears, we are interested in the very first slider, which adjusts the backlight.

Method 1

This method helps to change the brightness through the system settings. Suitable for any version of Windows (7, 8, 10). It is a little more complicated than the previous one, but it allows you to make more detailed settings.

In the system tray (at the bottom right of the screen), click on the power icon. Usually it is a different variation of the battery pattern. In the window that appears, select the item “Adjust screen brightness”.

A large window will open, at the bottom of which there will be a slider for adjusting the backlight. Here it can be either decreased or increased.

By the way, you can enter these settings in another way: Start. Control Panel. Hardware and Sound. Power.

Adjusting brightness in Windows. Automatic brightness adjustment with f.lux software

If you lower the brightness of the monitor due to the fact that your eyes get tired of working at the computer, then I recommend installing the f.lux program. This free utility that automatically changes the monitor backlight depending on the time of day.

In addition, f.lux makes the image a little yellow-orange, minimizing the amount of blue that is harmful to the eye. A SIMilar principle is used in almost all computer glasses.

But no one gives out such devices for free. In addition, the eyes will involuntarily focus on the glass, which can affect vision with prolonged use.

Run the downloaded file.

We agree with the program rules.

The program is installed almost instantly and asks to restart the computer, after which all that remains is to indicate your location. We print the name of our settlement, click Search and OK.

Now the program will run every time the system boots and will be in the tray (at the bottom of the screen, on the right).

Through this icon, you can manage f.lux: change settings, disable.

This program is removed in the same way as other computer applications: Start. Control Panel. Programs. Uninstall a program.

Monitor brightness not adjusting after updating to Windows 10 1803

Some users are faced with the fact that after installing the latest Windows 10 1803 (April Update) on many laptop models, the brightness of the monitor stopped adjusting. The brightness is turned on at full at any position of the brightness slider in the settings. The brightness cannot be changed using the keyboard function keys.

In almost 100% of cases, rolling back to Windows 10 version 1709 helps to solve the problem with display brightness. But, of course, this is not an option. There are easier solutions for Windows 10 1803.

First of all, check if you have enabled the “Very bright” tile in the notification bar, perhaps you cannot reduce the brightness because of it.

If the dimming issue occurred immediately after upgrading to Windows 10 1803, install the latest cumulative update KB4284835 (OS Build 17134.112) dated June 12, 2018. According to information from Microsoft, it fixes an issue with brightness control on laptops running Windows 10 1803:

Screen brightness does not change on a Windows 10 laptop

Some users complain that after a clean installation, updating to Windows 10 from a previous version of the OS, or installing a new build of Windows 10 on laptops, the screen brightness control stops working. When you try to increase or decrease the brightness with the dedicated keys or FnF11 / F12 / other combinations (depending on the laptop model), nothing happens. All other combinations and function keys work correctly.

In most cases, the problem with adjusting the brightness in Windows 10 is related to the monitor and video card drivers (most often the problem occurs on devices with Intel Graphics and AMD Radeon graphics cards). However, there are other reasons as well. Let’s take a look at a few easy ways to fix the problem with the inability to change the brightness on a laptop with Windows 10.

  • Monitor brightness not adjusting after updating to Windows 10 1803
  • Disabled Generic Pnp Monitor
  • Update your video adapter driver
  • Screen Backlight and KMD_EnableBrightnessInterface2 Registry Option
  • Brightness control does not work after installing TeamViewer
  • Fn brightness keys do not work on laptop
  • Brightness not adjusted on a laptop with an Intel graphics card
  • Switch to Microsoft Basic Display Adapter driver

Brightness control does not work after installing TeamViewer

Some users have encountered the brightness control in Windows 10 not working after installing the TeamViewer remote control software. The fact is that during installation TeamViewer adds its own display driver Pnp-Montor Standard to the system, which is used to compress graphics and optimize traffic.

Try replacing the driver for this device with “Generic PnP Monitor” (RMB. Update drivers. Select from the list of already installed drivers).

Fn brightness keys not working on laptop

If you find that the brightness control in Windows 10 settings works fine, but the function keys (Fn) for brightness control on the laptop keyboard do not work, most likely you need to install additional software from the laptop manufacturer.

Each manufacturer names the utilities differently. Please note that you need to download laptop utilities only from the manufacturer’s official website, or from the installation CD / DVD that came with the device. Below are the names of utilities for popular laptop models:

  • ASUS. ATK Hotkey Utility
  • Sony Vaio. Sony Notebook Utilities
  • Dell. QuickSet
  • HP. HP Software Framework and / or HP Hotkey Support
  • Lenovo. Hotkey Features Integration for Windows 10 or AIO Hotkey Utility Driver

Update your video adapter driver

The brightness issue may be related to the current video driver. First of all, check that your video card is enabled in the device manager (by analogy with the method above).

If the previous method did not help, try to automatically update the video adapter driver (unless, of course, you have disabled automatic driver updates).

In the device manager (the same devmgmt.msc console) expand the Display adapters section, find your video card, right-click on it and select Update Driver Software. Then we select the option Search automatically for updated driver software and wait until Windows 10 finds and installs the latest driver (of course, there must be an Internet connection).

If automatic driver update did not fix the problem with the brightness control not working in Windows 10, try uninstalling the current driver and installing the latest driver from the manufacturer’s website.

If it doesn’t help, go to the next method

Switch to Microsoft Basic Display Adapter driver

The last thing you can try if all the listed methods did not help is to use the standard Microsoft Basic Display Adapter driver for the video card.

  • To do this, select the video card in the Device Manager equipment console, right-click on it and select Update Driver Software from the menu
  • Select Browse my computer for driver software-Let me pick from a list of drivers on my computer
