How to adjust brightness on an acer laptop. Changing brightness through the "Control Panel"


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 we will figure out how different ways You can change the screen brightness on your computer or laptop.

Let's start with PC. Everything is quite simple here. Since there is no need to save battery power, the brightness is adjusted here relatively rarely. 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 used more often, especially if the device is unplugged 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 To do this, use 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 click 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 way is to adjust the brightness via installed drivers for a video card. Find it in the list of Control Panel items and click on it.

Or expand it in the tray hidden apps 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.

As for the settings, the methods are quite varied, and which one to use is up to you. However, if we're talking about only about brightness, the best option buttons will become and But if you need to produce fine tuning, it is better to apply software both the operating system itself and the programs included in the control software graphic cards, especially since this is exactly what they are designed for.

Question from a user

Hello. The brightness on my laptop began to change spontaneously: when the image is dark, the brightness drops, and when it is light, it is restored to its normal level.

How can I get rid of this problem, otherwise my eyes are starting to get tired because of it? OS: Windows 8, graph. accelerator (video card) Intel HD 4000 (built-in).

Good day!

This problem began to appear more and more often after the release of Windows 8 (this OS introduced the ability to adaptively adjust the brightness, depending on the picture on your screen). Also, some laptops are equipped with special software and sensors that determine the level of light in the room and use it to adjust the brightness of the screen.

There is nothing wrong with this, but in certain cases such a change does not allow it to work normally and interferes with the user. In this article I will tell you in detail how you can disable this. spontaneous change brightness...

Eliminate automatic monitor brightness changes

1) Disable adaptive brightness control

This is the first thing to do. This option is available in Windows 8, 8.1, 10. Those who have Windows 7 can omit this part of the article.

You need to open the power settings section:

  1. or via the following address: Control Panel\Hardware and Sound\Power Options
  2. or by pressing the Win+R keys and entering the command powercfg.cpl (see screenshot below).

In power settings: follow the link "Setting up the power plan" in the selected mode (in the screenshot below - this is balanced mode. The selected mode is marked in bold black).

Now find the tab among the settings "Screen" and open it. Here in the tab there are 3 key settings:

  1. screen brightness from battery and network: set the values ​​that suit you;
  2. screen brightness level in dim mode: set exactly the same values ​​that you have specified in the tab "Screen brightness";
  3. turn off adaptive adjustment brightness from mains and battery (see screenshot below).

Now save the settings and try to look at light and dark pictures (for example) to evaluate whether the brightness changes. Usually, similar settings completely eliminates this problem...

Update 06/10/2018

If you are using Windows 10, pay attention to its control panel (to go to it, press Win+i). In chapter "System/Display" there is a special a setting that allows the laptop to change brightness as the ambient light changes. Turn it off too!

2) Setting up the power supply for the video card

The laptop itself can reduce the brightness when certain modes work. For example, IntelHD video cards support display energy-saving technology and extended runtime in games when running on battery power. Similar technologies are available in both AMD and nVidia.

First you need to go to the settings of the video card driver (you can do it through - see the screenshot below), or you can do it through the tray icon, next to the clock.

Settings Intel graphics(trey)

Important!

If you do not have a tray icon, and there is also no link to graphics settings in the control panel, most likely you do not have the drivers installed (it is likely that you have a “universal” driver that was installed when Windows installations). In this case, I recommend programs for updating drivers:

They need to set the following:

  1. set the energy saving parameter to maximum performance mode;
  2. disable extended runtime for games on battery power;
  3. disable the display energy saving technology (screen below - see arrows).

Note!

For example, in video cards from AMD - you need to open the "Power" section, then turn on maximum performance, and disable Vari-Bright technology (this AMD technology, allowing you to adjust the brightness).

Vari-Bright disabled! (AMD Graphics settings) / Clickable

3) Sensor monitoring service

There is one service in Windows that monitors sensors and adjusts the display lighting, depending on the lighting of the room in which your device is operating.

I can say that sometimes the service does not work correctly and can affect the brightness adjustment, even if you do not have any sensors!

How to disable sensor monitoring services

Open a window with services: the easiest way is to press keys Win+R, enter services.msc, press Enter. The method works in all versions of Windows.

Next in the list you need to find the service "Sensor Monitoring Service" , open it. In the column "startup type" set [disabled], and stop the service itself, so that the status appears as "Stopped" (see screenshot below).

Then save the settings and restart the laptop.

4) Laptop control center

Certain laptop models include a control center among the software installed with the drivers. For example, in the line of VAIO laptops from SONY there is VAIO control center .

In this control center, for example, you first need to open the tab "Power supply" and set high performance, as well as disable the function that extends battery life (see screenshot below).

High Performance // Power // VAIO Control Center

Picture Quality // VAIO Control Center

Actually, it is hardly possible to give a description for each of these centers. The VAIO Center is shown above as an example of such software.

Lenovo laptops also have something similar: various night modes, dynamic changes in brightness, contrast and other things can significantly change the quality of the picture on the screen. It is recommended to disable them all (by at least at the time of setup and adjustment).

5) Problems with hardware

A change in screen brightness may be due not only to software settings, but also with faulty hardware. In what cases can you determine that the laptop hardware is to blame:

  • if not only the brightness has changed on the screen, but also stripes, ripples, and dots began to run (as in the example below);
  • if when you increase/decrease the brightness on the monitor, absolutely nothing happens;
  • if the brightness changes even without changing the picture on the screen and without changing the lighting conditions in the room;
  • if the brightness in different parts of the screen is different.

To help!

If you have stripes and ripples displayed on your monitor, I recommend that you read my other article:

Stripes and ripples on the screen / As an example

Good luck!
