Monitor brightness what. Spontaneous change in monitor brightness - the laptop changes the brightness itself! Why? Secondary setting method

Users of Windows 7/10 operating systems often need to adjust the screen brightness. This is a fairly simple procedure, but some owners of computers, laptops and tablets often have difficulty performing it. In this article we will look at all possible ways to adjust the brightness of the monitor, so that after familiarizing yourself with the material, even novice users can easily carry out this operation.

Adjusting screen brightness using standard Windows 7/10 tools

The simplest and most obvious path to brightness settings within the operating system itself is through the Windows Control Panel. We go into it using the Start menu, and then select the “Power Options” section (in the “Small Icons” or “Large Icons” display mode).

At the bottom we see the “Screen Brightness” slider, by moving which you can increase or decrease the backlight intensity of your monitor.

It is also possible to go directly to the settings of the selected power plan. Here, if you are using a laptop, you can separately adjust the brightness for battery and mains modes.

Owners of modern portable devices running Windows 10 should be aware of one more trick. Many new laptops are equipped with a light sensor that allows adaptive adjustment of screen brightness. That is, the “ten” automatically adjusts the backlight level depending on the amount of light hitting the sensor. It is clear that this function does not always work correctly, often setting an inappropriate brightness level. Therefore, the question quite reasonably arises of how to disable it. You can do this by clicking on the “Change advanced power settings” link in the settings of the current power plan.

In the window that opens, expand the “Screen” tab and switch the “Enable adaptive brightness control” option to the “Off” position. Click the “Apply” button to save the settings.

Adjusting brightness using the video card driver

Another proven way to change the screen brightness is to adjust it using the video card driver. Let's look at this method using Nvidia drivers as an example. Right-click on the desktop and select “Nvidia Control Panel” from the context menu.

In the settings tree on the left, open the “Display” section and select the line “Adjust desktop color settings” from the drop-down list. In the right area, set the switch to the “Use NVIDIA settings” position and move the “Brightness” slider in one direction or another, thereby increasing or decreasing the backlight strength.

Adjusting the display brightness on a laptop

Laptop computers allow you to control many settings using keyboard buttons. Typically, a special “Fn” key is used for these purposes, working in combination with other keys. For example, adjusting the screen brightness on a Samsung RV515 laptop is done by pressing the following button combinations:

On different laptop models, the backlight intensity is adjusted using different key combinations. The combination of Fn and any of the function keys in the F1-F12 range is often used. You can learn more about ways to change the brightness of your laptop's display in its manual.

Setting the brightness on the monitor itself

In most cases, modern monitors have their own buttons on the body for controlling settings for color, contrast, brightness and other parameters. As an example, consider the LG IPS236 monitor. It has several touch buttons on the control panel, press any one and get to the “Monitor Setup” menu.

Select the first item “Menu” and see the scales for adjusting brightness, contrast and clarity. Using the arrows, move to the desired line and set the optimal value.

The issue is resolved in a similar way with other monitor models, only the configuration and location of the button panel differ.

In principle, many screen settings, including brightness, can be adjusted in the monitor itself. And here it will no longer matter what operating system is installed on the computer. Instructions for manually setting parameters are included with the monitor upon purchase; it can also be downloaded from the manufacturer’s website in electronic form.

Conclusion

That's all we wanted to tell you about methods for adjusting screen brightness on a desktop computer and laptop. We hope that after reading this material you will no longer have questions about how to increase or decrease the brightness of any type of display with just a few simple steps.

You can work, play or spend time on the Internet at the computer at different times of the day. For example, during the day in good lighting, the screen should also be bright enough so that what is displayed on it can be clearly seen without having to look closely. But at night, on the contrary, it is better that it is a little muffled and does not hit the eyes.

Therefore, in this article, let us figure out how in various ways you can change the brightness of the screen on your computer or laptop.

Let's start with PC. Everything here is quite simple. Since there is no need to save battery power, the brightness is adjusted relatively rarely here. For this purpose, special buttons located on the monitor are used. They can be located either below or slightly behind. Find among them the one with the icon in the form of a sun and a pointer. If the pointer is pointing down, this means a decrease in brightness; if the pointer points up, it means an increase.

Now I’ll tell you about laptops. Here this procedure is used more often, especially if the device is disconnected from the network and you need to slightly increase its battery life.

To do this, you can use the “Fn” key in various combinations, which differ depending on the manufacturer of your laptop. Let's give examples of the most popular ones.

If you have ASUS then hold down “Fn” and press the “F5” button to lower, or “F6” to add brightness.

On Lenovo laptops, this is done using the up and down arrows. Press "Fn" and then the desired button. Just pay attention, for example, in the screenshot the arrow points up, and under it there is an orange sun with a downward pointer, which means this button will reduce the brightness.

On HP, the combinations can be different or, as in the figure below, “Fn” and “F2-F3”, or “Fn” and “F9-F10”.

If you have a device from another manufacturer, then I think you understand what buttons to look for. They should have an image of the sun - one larger, the other smaller.

The second way of adjustment is through "Control Panel". Click on the button and select the desired item, for those who have Windows 7. If you have Windows 10 installed, then right-click on Start and select the item of interest.

At the bottom of the window that opens there will be a slider, which you can move either to the right towards the sun, or to the left, then the brightness decreases.

In this window you can set the display brightness separately for running the laptop on battery and mains power. Remember that the smaller it is, the longer the charge will last. At the end, don't forget to click "Save changes".

You can open the required window in another way. Click on the battery icon in the lower right corner and select the item that interests us.

The third method is to adjust the brightness through the installed drivers for the video card. Find it in the list of Control Panel items and click on it.

Or expand hidden applications in the tray and click on the video card icon.

Then you need to select the item "Graphic characteristics".

Another option is to right-click on an empty space on the desktop and select the desired item from the menu that opens.

Whatever option you choose, a window like this will open. I have an Intel video card, so it looks like this. If you have a different manufacturer, the appearance of the window will be different.

Here in the left menu you need to find an item so that the “Brightness” field appears in the middle area. Move the marker to the appropriate value. Then click "OK".

That's all. I think now you can easily adjust the brightness of your screen on your computer or laptop. As for me, adjustment using the key combination with Fn is the simplest, and you choose the method that suits you.

Oddly enough, quite a lot of people suffer discomfort because they do not know how to reduce the brightness of the screen on their computer. For many users who work at a computer for a long time, the normal brightness of the monitor can cause fatigue and even burning in the eyes. In this article, using an example, we will look at how you can reduce or increase the brightness of a computer screen.

How to adjust brightness on a laptop?

On almost any laptop adjusting screen brightness is quite simple. There are special keyboard shortcuts for this.

Press the "Fn" and "Left Arrow" or "Fn" and "Right Arrow" keys (you may have other brightness keys. Look for the "sun" icon on the keys) to adjust the desired monitor brightness level.

Fn key in combination with the top row or arrow keys can perform a specific action that is often written on the keys themselves. If these combinations do not work on your laptop, this most likely means that the laptop does not have drivers (software) that allow you to use hot keys. If there is such a problem, look at the very bottom “Method 2”.

How to adjust brightness on a desktop computer?

The easiest way is to use the buttons on the monitor itself to go to the menu and adjust the brightness there. If for some reason you cannot adjust the brightness using hardware, there are two more ways.

Method 1. Go to your computer's video driver settings. You can almost always find it near the clock in the “Hidden Icons” tab. Next, in the driver itself you need to find “Adjust color parameters” (yours may be slightly different) and then move the sliders there to achieve the desired brightness level.

Method 2. If you are unable to make friends with your computer's video driver, you can download a small program that will do everything for you. For example, the Monitor Bright program allows you to change the brightness of any monitor. Download and run the program. The program is very easy to use.

You only need to enter a percentage value from 0 to 100 in a special window.

If you enter "0" the brightness will become maximum. If you enter a value of 20, the brightness will decrease by 20%, etc. This way you can adjust the desired screen brightness on any computer in just two clicks. We hope the information in this article was useful to you! Good luck.

The bulk of the power consumption of a laptop PC comes from the screen backlight. Manufacturers specifically set them to low power to improve battery life. For many people, such brightness becomes unacceptable, so it will be useful to know how to make the screen brighter and adjust the image.

How to adjust brightness on a laptop

If you are sure that your monitor is too dim, there are options to increase the screen brightness on your laptop. Each manufacturer left the opportunity for users to adjust contrast levels, color rendering, etc. You can change the power of the screen backlight in the following ways:

• through the power menu;
• built-in Windows program;
• using hot keys;
• through additional applications.

Using a keyboard shortcut

The easiest way to increase the brightness of a laptop screen is a combination of buttons. All global manufacturers of laptop computers (Asus, Lenovo, Samsung, HP, Acer) have hotkey combinations via the Fn function button by default. It is located on the very bottom line of the keyboard, usually between Ctrl and Win. Instructions on how to change the screen brightness on a laptop using function keys:

1. Find a key on your keyboard that has a sun or light bulb on it. On different models, these can be either arrows or one of the F1, F2, F8 buttons.
2. Hold down Fn, then you need to press the key with the image of the sun several times. The backlight should change gradually, set the required level.
3. You can do the reverse procedure in exactly the same way. Nearby there should be a button with the sun, but not painted over inside, which means you can reduce the intensity of the backlight.

Via power settings

The computer options are programmed to make the screen dark to save battery when the PC is disconnected from the network. If desired, you can configure different operating modes so that the monitor does not become dim even when disconnected from the network. To do this you need:

1. Go to the Start menu.
2. Go to the "Control Panel" section.
3. Find the item “Power Options”, click on it.
4. Use the "Setting the display to turn off" section.

This menu has two settings options: from battery and from mains. You can set specific metrics for these two states. You will be asked to set values ​​for the time after which the monitor will turn off, go into sleep mode, and the screen brightness level. Some laptop PC models may have several operating modes, for example, Asus suggests using Performance, Quite Office, Movie, and you can make changes to each of them.

How to increase brightness on a laptop using a special program

Another option for increasing screen brightness on a laptop is to use additional programs and system functions. Manufacturers offer to install software for their products along with drivers. For example, Intel offers to use a special utility, Intel HD Graphics, which can usually be found on the taskbar next to the clock. For AMD, these functions are performed by Catalyst Center, which provides a wide range of options for making changes to display settings.

If you want to easily and quickly increase the backlight power on your monitor, you can use the built-in menu from Windows. To do this:

1. Right-click on the battery image.
2. Select Windows Mobility Center.
3. In the window that opens, use the slider to increase the required indicator.

What to do if the brightness on the laptop does not change

Sometimes adjusting the laptop screen brightness does not have the desired effect. This is not a reason to immediately go to the service center; sometimes the problem lies elsewhere. First, you should check the availability of drivers for the video card and their relevance. It is likely that the graphics driver simply does not know how to react to your actions. You should also check the availability of keyboard drivers and the functionality of the Fn key. Try using it to increase or decrease the volume of the speakers.

In the worst case, it is not possible to increase the power of the lamps due to a hardware problem. Over time, the backlight element of the monitor may break, the resource of the part may be exhausted, the cable may fray or come off. In such cases, you should contact the service department to find out the cause of the breakdown and fix it. Before taking your computer for repair, try all the methods described above.

Pros and cons of function keys when adjusting laptop screen brightness

On the laptop there is a way to change the brightness of the screen among F1-F12 with an image of the sun and next to “+” to increase the brightness, or “-” to decrease it. You need to hold Fn and the corresponding one from F1-F12.

The bad thing about this method is that Windows can then easily return everything back. Therefore, it is better to make settings using a proprietary Windows 7 tool, that is, through Power Options, described at the beginning of the article.

By the way, if you reinstall the laptop operating system from a non-native distribution, then many of the functions of the laptop’s function keys will NOT work, unfortunately.

Changing the brightness of a laptop screen using a special program

Advanced laptops may have their own advanced options for adjusting screen brightness. For example, AUTOMATIC screen brightness adjustment. If you set this option, the screen brightness will automatically increase in bright light and vice versa.

For example, Sony Vaio has such settings in the Vaio Control Center program.
