The influence of bright computer screens on the brain is underestimated by many. Sitting at the computer in the dark leads to suppression of the production of melatonin, which gives the body a kind of signal for sleep. This, subsequently, leads to sleep disturbance and fatigue in the daytime. This happens because of the excessive amount of light that comes from computer monitors, laptops, or displays on phones and tablets. That is why it is advisable to reduce the brightness of displays at least half in the evening and at night. If you use a laptop or phone, this step will also help save battery power. In the article we will tell you how to reduce the brightness of the computer monitor and laptop.
How to change the brightness of a laptop display?
Each laptop is different, so adjusting the brightness and contrast of the screen may differ from the steps provided in this article. It should be noted that the brightness level may be limited by your power settings. Method 1 - Adjust the brightness using the keys
Most laptops support changing the brightness level using a function key in combination with another key. For example, by pressing and holding a function key (abbreviated “Fn”) and the up arrow or down arrow, you can increase or decrease the brightness of the screen. The key used to adjust the brightness with “Fn” may differ depending on the specific laptop model, but the symbol remains the same everywhere - the sun icon.
Method 2 - brightness control through the control panel
You can also adjust the brightness through the control panel, in the display settings. To do this, do the following:
Method 3 - Change the brightness through the driver software of your video card
If you have installed one of the popular video adapters (Nvidia, AMD or Intel), you can change the brightness, contrast, gamma settings in the driver’s own configuration window.
For NVIDIA Graphics
For AMD Graphics
AMD / ATI video drivers also have the ability to change the brightness, contrast, and gamma of the display, although access to the settings panel for these values \u200b\u200bmay vary between driver versions. For example, in the “Catalyst 10.2” version, to enable brightness control, go to the “Color” menu. You can open the program by right-clicking on the desktop and select the “Catalyst Control Center” item from the context menu.
For Intel Graphics
Method 4 - If the above methods do not work
If the keyboard combination with the function key does not work, and you have made the appropriate adjustments to the Power Options, then most likely your computer has problems with the video card drivers. This usually happens after updating the driver. In this case, we recommend either rolling back to the previous version of the driver, or performing a clean installation. A clean installation involves the complete removal of the current driver from the OS (including additional software) and the installation of a new driver.
If none of the options helped, then most likely the problem is either in the operating system itself or in the hardware.
How to change the brightness of the desktop monitor?
If you have a stationary computer, then the above methods are also applicable to it, however, it is much more convenient to use the functionality of the monitor itself to calibrate the brightness parameters. Almost all monitors have physical or touch control buttons. Usually there are 4-5 of them: the power button, menu, auto-tuning, left and right arrows.
Of course, depending on the model, their number may vary. For example, Samsung’s new monitors use a 5-way joystick.
To adjust the brightness, press the "Menu" button and go to the brightness and contrast settings. Use the left or right arrow keys to set the desired value.
If you have a different control circuit, refer to the instructions for your monitor that came with it.
- In a room where the sun is shining, it is better to pull up the curtains a bit and set the brightness at the level of 15-30%. Here, of course, everything is individual, but more than a third of the maximum brightness level should not be set. If, nevertheless, the sun shines directly on the display, then set the maximum level.
- If your work is related to design or photographs, then you should remember that when the brightness is reduced, color distortion is possible.
- Try to set the lighting so that its light does not fall directly on the monitor. This can cause glare and discomfort in the work.

A graphic control panel window will appear on the screen. In this window, select "Display" .
In the next window, go to the tab "Color" . There is an item "Brightness" which can be customized. If in your case there is no brightness adjustment, but, for example, the minimum brightness is too high for you, then you can add warmth to the screen, which will make it more comfortable to use the computer in the complete absence of lighting.
If you know about your ways to adjust the brightness, share them in the comments.
If you are having trouble adjusting the brightness or contrast of your laptop screen, keep in mind that each laptop model (and each operating system) is slightly different. In this article, we will discuss some common ways to adjust brightness and contrast on a laptop computer. If, for example, you have questions, then you can immediately write them in the form of comments on the site. Also, be sure to indicate your laptop model and version of the operating system.
How to reduce brightness on a laptop and computer?
This is done as always very simple. Follow our instructions, further listed on the site. And in a few minutes you will be able to understand how this function works.
Adjust brightness using your laptop keys
On most laptops, you can adjust the brightness of the display using special keys on the keyboard. Keys are usually indicated by a brightness symbol (Unicode brightness symbol).
Brightness keys are often function keys that have a special function if you press them while holding the Fn key.
The Fn key is usually located to the left of your space bar. The brightness function keys can be located at the top of the keyboard or on the arrow keys.
For example, on a Dell XPS laptop keyboard (figure below), hold down the Fn key and press F11 or F12 to adjust the screen brightness.
Other laptops have keys that are completely designed to control brightness. There is no Fn key on the HP Chromebook's keyboard (pictured below) - just press the brightness keys.

Control screen brightness in power settings
After adjusting the brightness of your laptop, it should automatically save the new settings. If the brightness settings are not saved after the computer reboots, they are probably overridden by the settings in the Power Options menu. If so, you will need to create a custom power plan that you can execute using the Power Options utility in the control panel.
Driver issues
If the key combination method does not work, and you have made the appropriate adjustments to the power settings, most likely there is a problem with the video driver on your computer. Problems with drivers usually occur after updating video drivers. The monitor driver may also cause this problem. To resolve possible monitor-related problems, reinstall the monitor by following these steps.
- Open Windows Device Manager.
- Click the + arrow next to Monitors to expand the list.
- Highlight all detected monitors in the "Monitors" section and click "Delete" to remove them from the computer.
Once the monitors are removed from the device manager, in the "Action" section, select "Scan for hardware changes" to allow Windows to re-detect the monitor and install the appropriate drivers.
Finally, we also recommend downloading the latest video drivers directly from the official website of the video card manufacturer. If this problem occurs because you updated the drivers, install an earlier version of video drivers to see if this fixes the problem.
Hello dear readers! Today, more and more people are buying laptops, and I have often heard the statement when users told me that managing a laptop is more complicated than a computer. In fact, this is not so, and for example, we will discuss the question of how to adjust the screen brightness on a Windows 7 laptop. With this instruction you can reduce or increase the brightness if it does not suit you. In order to have a better perception of the text and for more realistic color rendering of digital images.
On the front panel of the laptop screen there is no button that serves to adjust the brightness of the screen and this fact leads to a stupor of users.
There are several options for changing the brightness of your laptop screen.
Press the “Start” button, select “Control Panel” - “System and Security” and “Power Supply”. The slider located at the bottom of the Screen Brightness screen needs to be moved to the desired position. The screen brightness will change automatically.
In order to increase or decrease the brightness on the laptop screen, you can use a special key combination. In laptops there is such a key as “Fn”, which, when pressed with other keys, can perform various functions.
You can read more about hot keys in the article “” and “.
Keys that combine with the Fn key are usually highlighted in a different color on the keyboard, usually blue. The Fn key is located at the bottom left of the keyboard near the Ctrl, Windows, Alt keys, and the bottom right near the Ctrl key and left arrow.
To change the brightness of the screen, often on laptops there are keys on which the sun is painted. "Fn" + "sun -" means to decrease the brightness, and "Fn" + "sun +" to increase.
In order to change the brightness of the screen, in some laptops, you need to perform a combination of the “Fn” keys and the arrows. “Fn” and the down arrow decrease the brightness of the screen, while “Fn” and the up arrow, on the contrary, increase the brightness. But there may be another key - this information needs to be clarified in the user manual that comes with the laptop, or can be viewed on the Internet, for this you need to specify the make and model of your laptop.
Also, to change the brightness of the laptop screen, you can use various programs. Typically, such programs can be downloaded on the official website of the laptop manufacturer.
That's the whole answer to the question of how to adjust the screen brightness on a laptop.
This is where I end the article.
Tired of peering into a dark laptop screen? Increase the brightness! The procedure for this simple event may vary for different laptop models, but in general the process remains the same. To change the brightness, you can use hotkey combinations or use the capabilities of the operating system itself. Choose the method that you like best.
Use keyboard shortcuts to increase brightness.
The fastest way to increase brightness is with special keyboard shortcuts. For different laptop models, such combinations may vary. In most cases, the brightness changes by simultaneously pressing the Fn button and one of the F keys (F1-F10). Also, the brightness can be adjusted by a combination of Fn and arrow keys.The combination can only be determined empirically. As a rule, there is a special marking in the form of a “sun” on the corresponding buttons. Hold Fn and click on the brightness increase button until you reach the desired result. If you did not succeed in adjusting the screen settings in this way, we use the software method.
We work through the control panel
The procedure is as follows:First step. Open Start.
Second step. We go to the Control Panel.
Third step. Find the Screen section and open the Brightness Settings.
We see the power settings menu. We look down and find the brightness control slider. Drag the slider in the desired direction.
You can also get into this menu in a different way. To do this, we find in the lower corner next to the clock a battery icon. We click on it with the right button of our mouse, open the "Power Options" and perform the familiar actions.
And if the brightness does not change?
If you did not manage to change the brightness using the hot keys, the problem may lie in the banal lack of drivers for the Fn function button. Download the necessary driver on the website of the manufacturer of your laptop and install it. If the button works (for example, it allows you to adjust the sound level), check the health of the video card drivers.The worst case scenario is a hardware problem. For example, a backlight lamp or some kind of cable may break. To troubleshoot such a plan, you will have to contact the repair. Now you can adjust the brightness level. Follow the instructions and everything will work out.
Many users, either on duty or for personal reasons, have to spend a lot of time at the computer. And not the last role in the comfort of work is played by the brightness and contrast of the image on the screen of a monitor or laptop. Oversaturation or poor lighting may make your eyes tired. Let's see how to make the necessary settings using a few simple tools.
How to change the brightness on Windows 7 (or any other system) on a desktop computer
First, consider the moment the system starts. The normal mode of image perception is usually associated with the user when the welcome screen appears on the monitor. It is only by his appearance that one can judge how comfortable he is perceived by the eyes. Immediately attract attention and brightness, and contrast. Changing one of the parameters on stationary computers can be completely elementary.
It's no secret that it is in desktop PCs or workstations that the system unit and monitor (or several) are used separately. Their design is such that directly on the front panel there are one or two buttons: increase or decrease brightness.
In addition, if, as it were, in the question related to how to change the brightness of the screen or the contrast of what is displayed on the monitor, dig a little deeper, it is worth noting that any monitor has its own menu, called by a special button, in which there are extended settings, including the mode of shifting the image, stretching or narrowing it, etc. As you can see, personalization is quite simple.
How to adjust the screen brightness on a laptop
With laptops, this is even easier. Since the screen is an integral part of the entire structure, there are no special buttons on it, as provided for stand-alone monitors. Nevertheless, the question of how to change the brightness on Windows 7 or any other system (there is no fundamental difference) is solved using special keyboard shortcuts.
As a rule, the brightness parameter is changed using the Fn button in combination with either the function keys, on which there are up and down arrows and an image in the form of a sun. For example, in Fujitsu laptops, these are the keys F7 (increase brightness) and F6 (decrease), on others - F2 and F1, etc.
In some models, these settings can be made using the same clamped using additional standard buttons with left / right arrows (sometimes up / down).
on any windows system
Another simple method that allows you to solve the problem of how to change the brightness on Windows 7 is to right-click on an empty area of \u200b\u200bthe Desktop and select the screen settings item (personalization) from the context menu.
After entering the section, all available parameters will be displayed, which will not be difficult to change at your discretion.
Setting parameters in the power supply circuit
These were, so to speak, the simplest methods. Now let's see how to adjust the screen brightness on Windows 7 using our own system tools. To do this, you need to use the power section, access to which is carried out from the standard one. Here you need to select the item for changing settings, after which two main plans (balanced and saving mode) will be shown.
If for some reason they do not suit the user, they can be easily changed. To do this, use the item for changing additional settings, where the adaptive mode is turned on. You can also change the brightness in the “Screen” section, where the settings are presented in the category of display off parameters.
Using a graphics card management program
How to change brightness on Windows 7 another way? You can use special utilities for managing graphics adapters NVIDIA and AMD, which are initially installed in the system.
After calling the control program either from the system tray, if it is in the active state, or from the same Control Panel, you need to find the display parameters section in it, and then go to the desktop color adjustment item (for NVIDIA, for example). It is here that you can change the brightness, and contrast, and gamma, and image saturation, and much more.
The simplest test for comfort
So, the screen settings are set. Now you need to check how comfortable the perception will be. To do this, open a blank Word document. If you feel uncomfortable looking at it, you should change the screen settings. You can simply take a blank sheet of A4 paper and compare it with the white margin of the document. If the difference is not felt when looking at the sheet and the screen, then everything is in order. Finally, do not forget that when working at a computer or laptop for a long time, no matter how optimal the settings are, every 45 minutes it is recommended to take a break for about a quarter of an hour to relieve fatigue, including from the eyes.
As for the settings, the methods are quite diverse, and which one to use is up to you. However, if we are only talking about brightness, the buttons and will be the best option. But if you need to fine-tune it, it is better to use the software of both the OS itself and the programs included in the control software of the graphics cards, especially since they and calculated.
To improve results display brightness and contrast settings, use the display color calibration wizard (the display color calibration wizard will help you configure these and other color settings). The procedure for adjusting brightness and contrast depends on the characteristics of the display.
The brightness and contrast controls for some monitors are located on the front panel.
- OSD menu. The brightness and contrast settings of some displays can be adjusted using the on-screen menu, and then set the brightness and contrast in the final menu. Typically, you can view the on-screen menu by pressing a button, which is possibly called the “Menu” and is located on the front of the monitor.
- Laptop display. Laptop displays are not equipped with brightness and contrast buttons on the front panel. Most laptops do not have a contrast control. However, the brightness of many laptops can be adjusted by holding down the Fn key and pressing the corresponding function key to decrease or increase the brightness. When using the Display Color Calibration Wizard on a laptop, set the display brightness setting to maximum.
For more information about adjusting the brightness and contrast of the display, see the monitor documentation or manufacturer’s website.
Automatic brightness adjustment by adaptation
Adaptive brightness - This is a Windows feature that, using a light sensor, automatically adjusts the brightness of the display in accordance with the lighting conditions of the computer. To use this function, it is necessary that light sensors are installed and turned on on the computer.
To determine if the monitor of your laptop or computer supports the adaptive brightness function, in the "Power" window, you should find Enable adaptive brightness or view computer documentation.
Adaptive Brightness Triggering
- Open the Power Options window.
- For any nutrition plan, click Configure Plan.
- Press button Change advanced power settings.
