How to adjust the contrast of the monitor on a laptop. Spontaneous change in the brightness of the monitor - the laptop changes the brightness itself! Why? Using the capabilities of a desktop computer monitor
The easiest way to change the display settings on your home personal computer is with the control buttons on the monitor itself. The same buttons, depending on the monitor model, will help you change the contrast, color rendition, calibrate the screen position, and create different modes. However, there are many cases where hardware customization is not available, because some monitors for aesthetic purposes are assembled without function buttons. And the owners of laptops and netbooks are completely deprived of such an opportunity. Therefore, there is also software setting screen brightness by standard means Windows 7 or using third-party software.
Change brightness using Windows 7
This item is suitable only for laptop owners. Operating systems installed on a personal computer, as a rule, do not have such functionality.
Open the "start" menu, then "control panel" in the menu on the right. If your windows system is set to view in the form of categories - you need to go to "hardware and sound", subcategory "power supply". If the view in the form of icons is set, then at the very bottom of the list, find the "power supply" icon and open the appropriate section.
In the window for working with power supply, select the item "display off setting". Next, go to the power plan settings. One of the available sliders - just makes it possible to change the brightness of the screen.
In addition, there is another special way to adjust the brightness of the monitor on a laptop. To do this, you need to hold down the special function key FN and right / left arrows. For some laptop models, instead of the arrows, you need to hold down the keys with the sun icon. These steps are also valid for Windows 8.
Changing brightness using the video driver
This item will suit any user. To complete the settings, you need to go to the video card control panel.
Go to the "start" menu, then to the "control panel" in the menu on the right. If your windows system is set to view in the form of categories - you need to open "design and personalization", subcategory "panel NVidia management"(If you have NVidia hardware) or" AMD "(if the manufacturer is AMD). If the view in the form of icons is set, find the same icon and go to the corresponding section.
Oddly enough, quite a lot of people endure discomfort because they do not know how to reduce the brightness of the screen on a computer. For many users who work at a computer for a long time, the usual brightness of the monitor can cause fatigue and even a burning sensation in the eyes. In this article, for example, let's see how you can decrease or increase the brightness of your computer screen.
How do I adjust the brightness on my laptop?
On almost any laptop adjusting the brightness of the screen is quite simple... There are special keyboard shortcuts for this.
Press the "Fn" key and "left arrow" or "Fn" and "right arrow" (you may have other brightness adjustment keys. Look for the "sun" image on the keys) to adjust the level of the desired monitor brightness.
Fn key in combination with the keys in the top row or arrows can perform a certain action, which is often painted 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 allows you to use hot keys. If there is such a problem, look at the very bottom "Method 2".
How do I adjust the brightness on a desktop computer?
The easiest way is to use the buttons on the monitor itself to enter the menu and adjust the brightness there. If for some reason you cannot adjust the brightness in hardware, there are two more ways.
Method 1. Go to the video driver settings of your computer. You can almost always find it near the clock in the "Hidden Icons" tab. Further, already in the driver itself, you need to find "Adjust color parameters" (you may have it a little differently) and already there, moving the sliders - achieve the desired brightness level.
Method 2... If you failed to make friends with the video driver of your computer, 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 the special window.
If you enter "0" - the brightness will be maximum. If you enter a value of 20, the brightness will decrease by 20%, etc. Thus, you can adjust the desired screen brightness on any computer and in just two mouse clicks. We hope the information in this article was useful to you! Good luck.
You can improve the perception of text, make the color of a photo or video more realistic by adjusting the brightness of the screen. For desktops, this is done in the monitor settings. In contrast, in laptops, you can change the settings using the windows 7 system itself. This is due to the fact that in laptops the monitor is an integral part of the device itself.
Settings in windows 7
In order to change the settings, you need to go to the Control Panel. Here you should set the view in the mode of large or small icons. We select the section Power supply. In the window that opens, change the settings to those that are necessary.
If you click on the link Configure display off, we will be presented with a list of characteristics that can be changed. The settings are divided into those that will be when the laptop is running on mains, and if it will be running on battery power. In the latter case, it is recommended to set a lower brightness, which will help to save resource costs. In such a situation, when connecting and disconnecting charging, the brightness mode of the monitor will change.
So, in the power supply, you can select the desired plan or scheme. There are usually two options offered here: Balanced and Energy Saving. You can make a plan active by clicking on the button next to it. If necessary standard settings can be changed at your own discretion. To do this, click on the Power plan settings link.
Developers offer an additional plan, High performance... It is located at the bottom of the Power Options window. This mode consumes a lot of power, but at the same time provides maximum performance.
In addition, there is an Fn function key for laptops. It will be needed in order to quickly change the brightness in the direction that is necessary. So, on the arrows, you can usually see icons in the form of a sun or a triangle. On different models, they can be marked on various buttons... In order to adjust the brightness, you must press Fn and one of these keys.
As you can see, for laptops in windows 7 there are special modes that allow you to adjust the brightness of the monitor at your own discretion. If desired, all settings can be made manually. On personal computers there are special buttons on the monitor itself. By clicking on them, you can set the mode that suits you.
It will also be useful for you to learn how to set up Bluetooth in windows 7.
