What to do if the brightness does not decrease or increase

There are several reasons why this problem may occur. The most common ones are:

Reason 1: light sensor

Some expensive laptop models have an ambient light sensor that changes the brightness depending on the light level. Often this sensor interferes with setting the screen brightness that is comfortable for the user. And sometimes this sensor fails.

To solve this problem, you need to disable the sensor in the settings of your laptop and use one of the methods described above to set the optimal brightness level of the monitor.

Reason 2: malfunction of the backlight system

This is true for older laptop models, where glass tubes are used as the backlight, rather than LEDs. The fact is that the resource of these elements is limited and when they fail, the backlight turns off completely, but the user can see the image on the screen and think that the brightness level is set to the minimum value.

It is necessary to contact a specialized service, where professionals will replace damaged parts, but this procedure is not cheap, due to the inaccessibility of spare parts.

Reason 3: viruses

It is extremely rare, but it is worth mentioning it. Some viruses are capable of controlling the brightness of the screen, which interferes with normal operation.

It is necessary to scan your computer with an antivirus, and preferably several. To prevent reinfection, it is best to have an antivirus with real-time protection.

It is worth recalling that some of the described methods may differ or may not work at all on your computer due to different versions of the installed Operating System and individual characteristics of the laptop. So if one of the methods doesn't work on your computer, don't despair, try another one. Hope you enjoyed the article.

Parameters such as the brightness and contrast of the monitor or display are paramount when choosing a laptop. If they are accompanied by excellent characteristics, then this is conducive to comfortable reading, quick performance of all assigned tasks.

Laptop brightness and contrast are very easy to adjust

Otherwise, very rapid eye fatigue occurs, cramps, lacrimation and other undesirable consequences appear. However, you can adjust the brightness of your monitor yourself using some good advice from an experienced user on how to adjust the brightness of your monitor.

There are several options for solving this problem. At the same time, each option is available for understanding the sequence of actions and is unlikely to provoke additional questions related to misunderstanding of individual steps.

In general, all, even outdated notebook models, are set to average values of such parameters.

In addition, you may face a situation where your modern laptop will be able to independently adjust the brightness and contrast settings.

Indeed, modern manufacturers equip some computer units with such functionality. In this case, when the illumination in the room space increases, the brightness on the laptop is automatically reduced. In the same way, on the contrary, when the illumination is reduced, the laptop is able to increase the brightness itself to provide the user with a comfortable working environment, even for a long time.

If you are not the owner of such modern technology, but are content with slightly outdated samples that are not accompanied by such functions, you can still intervene in the process of adjusting the brightness and contrast, providing yourself with conditions under which the eyes will not experience stress.

Before proceeding to directly study the recommendations on how to increase the brightness of the monitor, each user must understand that such a setting directly affects the state of charge of the battery.

The higher the brightness, the faster the laptop will discharge.

The higher the brightness, the faster the battery will discharge. In this regard, being outside the reach of recharging the laptop from the mains, on the contrary, it is recommended to reduce the brightness and contrast settings.

Correction via OS

In particular, the brightness and contrast of the monitor can be adjusted by simultaneously pressing two buttons, one of which is Fn. This button is in most cases located at the bottom of the keyboard.

The second button on different models may be different, but its main reference point is, in addition to the main inscription, the presence of an icon with the image of the sun.

It is important to understand that there should be two buttons with the image of the sun. One aims to increase the brightness, and the second helps to reduce it.

Sun buttons let you adjust brightness

Often these additional buttons are arrow keys, which are located between the main keyboard and the numeric keyboard.

Having used such methods at least once, it will become clear to you not only how to reduce the brightness of the monitor, but also that such actions are not accompanied by difficulties.

Setting up the video card

If your device has an NVidia graphics card, just right-click on an empty space on the desktop. In the context menu that opens, go to the "NVidia Control Panel" option.

Now in the new window on the left side you will be able to see many different options, you need to go to "Adjust Desktop Color Options".

The second point of the proposed settings will be the proposal to choose a method for adjusting the color.

Find the item "Use NVidia settings", set a check mark next to it. After that, the settings for brightness, contrast, gamma will become active, you can again move the slider, choosing the optimal parameters for yourself.

If your laptop does not have an NVidia video card, but a Radeon, you need to download a special Catalyst application, which is endowed with the same functionality.

By the way, on the net you can easily find and download to your laptop a lot of various interesting applications that contribute to the selection of the optimal settings. In particular, NTest is one such application.

So, having read these recommendations, each user, regardless of his practical experience with a laptop, will be able to adjust the display so as to favor comfortable work that does not provoke fatigue, watery eyes and other undesirable consequences.

Then press the AUTO / SET key. The brightness adjustment window should open, in which you can change it.

I would also like to note that the monitor settings do not depend on which OS or driver is installed. They are regulated exclusively in the monitor. Each monitor from a different manufacturer has its own manual settings... You can find out the details of adjusting the lighting parameters of the screen of a particular monitor in the manual, which is completed with the sale or can be downloaded electronically on the manufacturer's website.

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

How to adjust brightness on a laptop

If you are sure that your monitor is too dim, there are options on how to increase the brightness of the screen on a laptop. Each manufacturer has left the opportunity for users to adjust the levels of contrast, 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.

With a keyboard shortcut

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

Find the key on the keyboard that depicts the sun or a light bulb. On different models, these can be either arrows or one of the F1, F2, F8 buttons.
Hold Fn, then you need to press the sun key several times. The backlight should change gradually, set the required level.
The reverse procedure can be done in exactly the same way. There should be a button with the sun next to it, but not painted over inside, which means the ability to reduce the intensity of the backlight.

Through power settings

Computer options are programmed to darken the screen when unplugged to conserve battery. If desired, you can configure different modes of operation so that the monitor does not become dim even when disconnected from the network. For this you need:

Go to the start menu.
Go to the "Control Panel" section.
Find the item "Power supply", click on it.
Use the “Setting the display to turn off” section.

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

How to increase the brightness on a laptop through a special program

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

If you want to easily, quickly add power to the backlight on the monitor, you can use the built-in menu from Windows. For this:

Right click on the battery image.
Select Widnows Mobility Center.
In the window that opens, use the slider to increase the required indicator.

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

Sometimes adjusting the brightness of the laptop screen 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, their relevance. It is likely that the graphics driver simply does not know how to respond to your actions. You should also check for 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 down, the resource of the part may be exhausted, the cable may be frayed or come off. In such cases, you should contact the service department to find out the cause of the breakdown and eliminate it. Before taking your computer for repair, try all of the above methods.
