Disconnect adaptive brightness on a laptop. Method 2: Disruption display block forever

The laptop or monitor of the Windows 11/10 computer is darkened

A laptop screen or a monitor from a computer running Windows 11 and 10 can darken or dull in games or when working for several reasons: damaged video driver, incorrect resolution, adaptive brightness on the monitor itself or in Windows 11/10 parameters is included.

Some monitors and laptops have an Adaptive Brightness sensor, which is responsible for adaptive brightness. If the lighting in the room is too bright, then the monitor begins to darken, and if too dull lighting surrounded by sensors, then the screen becomes brighter.

We will analyze in this instructions what to do when a laptop monitor or screen is darkened to a computer with Windows 11/10.

Disconnect adaptive brightness

If the laptop has a sensor for adjusting brightness depending on the surrounding lighting, then you need to turn off the function in Windows 11/10 of adaptive brightness. For this:

• Press Winr and enter Control.EXE PowerCFG.CPL ,, 3
• The properties of power supply will open immediately
• Expand the screen tab
• Expand include adaptive brightness adjustment
• Turn it off from the network and batteries

Windows 10 changes brightness on a laptop

After updating to Windows 10, on laptops there may be a problem with an automatic shift in brightness. The brightness of the Windows 10 laptop screen changes automatically to low and this can cause you irritation. If you are faced with this problem, most likely you have already tried to correct the energy consumption plan and change the value of adaptive brightness. (If so, immediately go to the end of the page to the point to replace the video driver), if not, start with point # 1.

Disconnecting adaptive adjustment

Click with the right mouse button for “Start/Start” (Windows logo on the right at the bottom of the screen) and select the “control panel” from the drop.down menu.

In the “control panel” we find “power” or if you have a grouped display “Equipment and sound power”

In the “power supply” screen, we find “setting up the power supply circuit”, go there.

Power ” /

In the parameters of the power circuit, click “Change the additional power parameters”.

We will make sure that we set up the parameters of the mode of the active scheme to the right of the name of the mode will be the signature [Active]. We lower the slider and find the “screen”. In the opening list, we check the parameters we need. Enable adaptive brightness adjustment [Off]. (Both from the network and from the network)

If after that the brightness continues to change, you need to replace the video card driver.

Replace the video gap

We go to the “Device Manager”. Click with the right mouse button for “Start/Start” (Windows logo on the right at the bottom of the screen) and select the “Device Manager” from the drop.down menu.

We find a video adapter in the device dispatcher you may have different, and most likely Intel (R) HD Graphic Family.

Press it with the right mouse button and select the item update the driver.

In the dialog box, which will come out after clicking, you need to select a search for drivers on this computer

In the next screen, we select the item Choose the driver from the list of already installed drivers

To turn off the annoying shift of brightness, select from the list of proposed drivers the base video adapter (Microsoft) (Microsoft) and press further to install it. The screen can blink, as when changing the screen resolution.

Upon completion in the equipment of the devices dispatcher in the video adapter section, you should have a basic video adapter, as in the figure.

Turn on adaptive brightness

• In the new window, click show. To open lists under it.
• Find and select each of the following values: the brightness of the display, the darkened brightness of the display and turn on the adaptive brightness.
• Change each of them to the desired settings
• Click app.
• Click OK.

Turn on the PNP monitor

• If not turned on, click on the device. If it is turned on, disconnect it
• Press the action in the upper menu of the device manager.

General information about the automatic brightness of Windows

Before we start, it is important to know that automatic (or adaptive) brightness is applied only to Windows devices with built.in screens, such as laptops, tablets and monoblocks of desktop PC. If you use an external monitor, you will probably not see elements of adaptive brightness control in the settings.

Some Windows devices automatically adjust the brightness of the screen depending on the surrounding lighting conditions, and some do not. If so, then these changes are based on the readings of the light sensor built into your device.

In addition, some PC allow you to automatically change brightness depending on what you view on the screen, which helps save batteries. Microsoft calls this function “adaptive control of the brightness of content” or CABC. Depending on which of these functions your PC with Windows supports, you can see one or two flags to control these parameters in the settings, which we will consider below.

How to disable adaptive brightness in Windows 10 or 11

When you are ready to disable automatic brightness, first open Windows settings by clicking Windows I. Or you can click the “Start” button with the right mouse button and select “Settings” in the list.

When the “Settings” application opens, in Windows 10, click the “system”, then select the “screen” on the side panel. In Windows 11, click the “system” on the side panel, then select the “screen”.

In the “brightness and color” section in Windows 10, look under the “brightness” slider and remove the flag next to “automatically configure contrast based on the displayed contents to improve the charge of the battery” or “automatically change brightness when lighting lighting”. If you see both options, remove both flags.

In Windows 11, click a small arrow next to the brightness slider to deploy a small menu, then remove the “help improve the battery, optimizing the displayed contents and brightness”.

If you see “automatically change brightness when lighting”, remove this flag.

After that, close the settings. From now on, the brightness of your screen will always remain the way you installed manually. Successful calculations!

Disable CABC in Windows 11

To disable adaptive brightness control for the contents of the screen, perform the following actions:

Open the “Parameters” application in Windows 11.

Go to the “System” section → “Display“.

Expand the subsection “brightness” (adjustment of the brightness of the built.in display).

Remove the box for “extend the battery work due to optimization of the displayed contents and brightness”.

After these steps are performed, the brightness of the display on a laptop or tablet with Windows 11 will no longer depend on the contents of the screen.

Enable CABC in Windows 11

To enable CABC in Windows 11, follow the following actions:

Open the “Parameters” in Windows 11.

Go to “System” → “Display”.

Expand the “brightness” subsection and set the “extend the battery work by optimizing the displayed contents and brightness”.

Everything, after performing these actions, the brightness of the display will change accordingly to increase the autonomous operation of your laptop or tablet.

The accessibility of the function depends on whether your GPU CABC device supports. If your video card supports CABC, the parameter will be available.

How to prevent the dimming of your laptop screen

Automatic darling on your laptop can sometimes irritate. In this article, we will show you how to disable the function of adaptive brightness, which leads to the dimming of the screen of your laptop. The solution is very simple and requires only a couple of settings in your power supply. Many modern Windows platform laptops are equipped with adaptive lighting sensors that regulate the brightness of the screen depending on the lighting. But, unfortunately, this function does not work as it should work in Windows, and this can cause some problems with your experience.

If the problem with a change in brightness constantly annoys you, this is what you should do to fix it:

• Go to the control panel, equipment and sound, power parameters.
• Click change the plan settings next to your active power plan.
• Click change the additional power parameters.
• Scroll down to the display. Then turn off the adaptive brightness in the section for both the battery and for connected modes.

Light adaptive sensors are available for laptops with Windows 7 and Windows 8. This function is also available in laptops with the Windows 10 operating system. So it was from the very first day of the production system for manufacturers.

Speaking about new versions of Windows 10, if you have established the latest version of the OS, keep in mind that the next steps may differ a little.

Here’s how you turn off adaptive brightness on your laptop under the control of the latest version of Windows 10:

• Type control panel in search/court
• Go to the “Equipment and Sound” tab “Power”.
• On the left panel, click “Select” to turn off the display
• Click on additional power parameters
• Click on the display and expand turn on adaptive brightness
• Install both parameters on OFF and then Apply.

Update the display driver

If you still have a problem with the darning of the screen, check if your display driver is updated. You can go to the device manager, select the display driver, click on it with the right mouse button and select “Update the driver”.

In addition, if you use the Intel video card, disconnect the function “Technology of energy.saving display”. Many users confirmed that quick solutions worked for them. Try it also, as this can be a response to the problems of dimming the screen of your laptop.

If you have other problems with the screen of your computer, you can check our article about solving the PCC pixel screen or laptop.

That’s all, the display of your laptop should no longer dull after performing these actions.

The PC and laptop monitor independently changes brightness: the causes and methods of solving

After starting the Windows 8 operating system, laptop users and PC began to notice the problem: with a dark image, the monitor brightness began to fall, and with a bright one. increase. increase. Such a spontaneous change in the brightness of the monitor is explained by the settings of the operating system and laptops that have built.in sensors for adaptive brightness adjustment. If your PC monitor changes brightness on your own, then you should try to apply the following settings.

Solving the problem with spontaneous change in the brightness of the screen

Users Windows 7, 8/8.1, as well as Windows 10 in cases where the monitor changes brightness on its own, they can try to disable the adaptive adjustment function. To do this, you should perform the following actions:

• A small window will open. You need to expand the “screen” branch and find three parameters:

• The brightness of the screen from the battery and network. We set our meaning.
• Brightness level in reduced brightness mode. Duplicate with the first item. If you set different values, then the brightness will change independently in accordance with the specified parameters.
• Adaptive adjustment of brightness from the network and battery. It can be disabled (there is no Windows 7 in Windows 7).
• Also, in the new operating system, you need to open the “Parameters”, “System”, “display” and remove the mark “automatically change the screen brightness when lighting”.

If you use an integrated or discrete video card, then a change in the brightness of the screen can be spelled out in the video accelerator settings. In order to change the parameters, it is worth performing the following actions (we will consider the example on Intel, all the others also have a graphics control panel):

• In addition to the maximum performance in this tab, you need to disable the expanded time of the games from the power and turn off the energy conservation technology for the display.

IMPORTANT! If you have a video card from AMD, then in the “power” section you need to enable “maximum performance” and disable the Vari-Bright option.

In almost all Windows assemblies there is a “observation service for sensors”. It is she who adjusting the lighting of the display. However, it is included mainly on laptops. This service can be disabled. This can be done in the following way:

In case the screen is not possible to set up and the display continues to change the brightness, then the problem may lie in the gland. It is necessary to carry out the full diagnosis of the installed equipment and retake the monitor, if it is connected to the PC (if you have a laptop, you can connect the monitor to the laptop and see if it changes brightness).

The vast majority of modern laptops are equipped with Intel processors along with integrated graphics, which often displays the image on the screen. In general, there is no problem in this, moreover, this allows you to disconnect a discrete graphics for energy saving when it is not needed. However, Intel for the latest generations of its video adapters came up with the “technology of energy conservation of displays”, which greatly interferes with the laptop from the battery.

Its idea is quite simple. to adjust the brightness depending on the content on the screen: for example, on a white page it will be higher, in the dark moments of the films. below. below. But, alas, in practice the changes in brightness are very strong and interfere with normal work (besides, they do not occur instantly, but slowly, which even more confuses). Of course, Intel added the ability to disable this technology. for this you need to go to the Intel Graphics Plant and turn it off: disconnect it:

But in practice, this often does not help: it happens that the brightness again begins to autumn after rebooting or after disconnecting from the power adapter, or the brightness correction itself simply decreases, but it does not completely disappear. Of course, Intel knows about this problem. it has been reported on the forums of technical support since 2015, however, the WHO there, although during this time there has been more than a dozen new drivers.

But still there is a solution. you need to go to the register, follow the way hKEY_LOCAL_MACHINE \ SYSTEM \ CONTROLSET001 \ CONTROL \ CLASS \\ 0000 (in some cases 0001) and find the FeatureTestControl parameter. Now click on it twice, switch to a 16-richety calculus system and increase the parameter by exactly 10 (I had 8200-that is, you need to write 8210; it should be understood that your value may be different):

That’s it, now you need to reboot, after which the authentication of the brightness will stop working, and this is indicated by the absence of its settings in the Intel graphics control panel when choosing work from the battery:

However, this only works before updating the graphic driver, but in practice the value of the FeatureTestControl parameter will simply reset 8200 default, that is, it will simply be necessary to replace it back by 8210. Crutch, you say you? Alas. yes, because Intel does not want to solve the problem on its own. On the other hand, the drivers do not go to the graphics from Intel very often, so there should not be serious problems with a change in meaning.

The instruction is completed on this, but I think a sufficient number of users had a question. why it works? Everything is simple-the FeatureTestControl parameter is essentially a binary line where each bit is associated with some kind of setting from Intel. The technology of energy conservation of displays is the fifth bit from the end in this line, and by default it is equal to 0. that is, to turn it off, you need to change this bit by 1, which is equivalent to adding to a binary line 10,000. However, in the register, the value is recorded in the 16-richety calculus system, and since 100002 = 1016, we just need to add to the value in the register 10.
