The operating system is a fairly complex mechanism, not protected from various errors and malfunctions. They can be associated with its various components. This article will discuss how to adjust the screen brightness in Windows 10, as well as how to fix some errors associated with it.
Windows Options
This is a slightly sophisticated way. It involves working with the parameters of the operating system. To implement it, follow the specified algorithm:
- Using the Start menu, launch the Windows Settings program by clicking on the gear icon;
- among all sections, find and open the one called the “System”;
- going to it, you will be taken to a tab under the name "Display";
- in the right part of the window you will have a slider - with its help you can adjust the screen brightness in Windows 10.
Hotkeys
On some laptops or keyboards, function keys are sometimes installed that can be used to adjust the brightness of the screen. For example, on a laptop, it will be a combination of Fn and the down or up key to decrease or increase the level.
To determine if this feature is available on your device, look at the keyboard. In addition to the arrows, the sun should be drawn on the buttons.
You can also make screen brightness settings in Windows 10 using the dedicated keys. They are located in the line of buttons F.
Battery indicator
This is perhaps the easiest way to change the percentage of brightness on the desktop. But this is only if you are working on a laptop. To implement such an operation, you must do the following:
- on the taskbar, find the icon showing the battery level ;
- click on it to open a window with detailed information;
- at the very bottom there will be a button with a brightness level indicator;
- Click on it and the percentage will change.
Now just adjust the screen brightness in Windows 10 as you need.
Action center
This is another way to change the brightness level of the monitor on both a laptop and a desktop computer. To implement it, run the following algorithm:
- On the taskbar, find the icon in the form of a message and open.
- The action center will open before you. Below is a quick action section. And above it is a proposal to expand the page. Perform this action.
- After that, additional icons will appear, among which you can find the one that displays the percentage of screen brightness in Windows 10.
- When you click on it, the level will rise by several percent. Continue the action until you reach the position that you need.
Power settings
The next way to change the brightness requires starting the control panel. To achieve the desired result, follow the conditions of the following instructions:
- using the search bar, start the “Control Panel” program;
- then go to the equipment and sound tab, and from there to the power section;
- a slider will be located in the lower right part of the window - with its help, you can adjust the brightness in Windows 10.
Mobility Center
The next option is to change the brightness of the screen. To execute it, follow the simple instructions that are given below:
- find the Windows icon on the taskbar and right-click on it with a computer mouse;
- in the list that opens, activate the second line with the inscription "Security Center";
- after that, a window will appear, one of the cells of which will be reserved for the screen brightness settings in Windows 10 - using the slider, set the desired level.
Now it’s worth moving on to solving the brightness problems that arise when the computer is running. The first is to study the one in which the brightness of the screen changes without your participation.
Automatic changes
New updates to the operating system from Microsoft have led many computers to face various problems. One of them is one in which the brightness of the screen on a laptop under Windows 10 changes automatically. The first option worth trying is turning off adaptive adjustment:
- Right-click on the “Start” menu icon, which is located on the left of the taskbar. A list pops up.
- In the second section, find and activate the control panel.
- In the new window, open the equipment and sound section, and from there proceed to the power settings.
- In the list on the left, find the power scheme settings tab. Open it.
- After moving to a new page, find and open the line for changing additional power settings.
- A small dialog box will appear. In the list, find the section called “Screen.” Open it and find the brightness subsection.
- After it is activated, the adaptive brightness adjustment off line appears. Turn it off and confirm your actions by clicking on the "OK" button.
Device Driver Replacement
Quite often, many problems in Windows 10 can be resolved by a software update. A similar case is no exception:
- Right-clicking on the Start menu icon, launch the context menu.
- In the list that appears, activate the line with the name "Device Manager". It is in the first section. Then a window opens with devices that are installed or connected to the computer.
- Among them, find the video adapters tab and expand it.
- Right-click on each of the devices and select the driver update function.
- A window will open in which you will be asked to choose where to look for software. You need to run a driver search on this computer.
- After that, click on the line to select software from already installed.
- To disable automatic replacement, run the installation of the base video adapter (Microsoft). Press the "Next" key.
- Upon completion of the installation process, you will change the section of video adapters in the device manager. Instead of the video card, the base software you have installed will be marked there.
Error changing brightness
Sometimes you can meet another problem when the screen brightness function in Windows 10 does not work. Let's dwell on some of the reasons that lead to such a situation, as well as explore ways to solve them.
Device disconnected
To find out whether such an assumption is the cause of the problem, you should go to the monitors section, which is located in the “Task Manager”, and then check to see if the down arrow is present there. If such a symbol is present, and the screen brightness in Windows 10 is not regulated, then your monitor turned off. You can fix the situation like this:
- on the line of the disconnected device, right-click on the computer mouse;
- in the list, select the line with the name "Engage";
- After that, restart the computer and check the device manager again.
Graphics card driver
Back to working with graphics software again. Unlicensed or outdated drivers can cause a failure of the elements that are responsible for changing the screen brightness level in Windows 10. It is worth noting the following reasons leading to this situation:
- Specific software was installed by the operating system itself at the time it was installed. As a result, the wrong version could be delivered. In a specific case, you just need to download the software from the manufacturer’s website, in accordance with the model of the installed video card.
- It may be that such software was downloaded, but not installed. In this case, the system will be unstable.
- The graphics adapter turned off (just like the screen). To fix the error, simply repeat the algorithm from the previous section.
Automatic driver update
Newer versions of graphics software can lead to conflicts. To prevent this from happening, you need to turn off the automatic driver update feature:
- Using the search bar, open the control panel and launch the "System" section.
- In the new window, find the "Change Settings" function. It is located in the subkey of the computer name.
- Go to the equipment tab and from there proceed to the "Device Installation Settings".
