How to disable monitor fading in windows 7. Turning off the screen on a running laptop
Connecting the system unit to the monitor is quite simple; to do this, you need to connect them with a cable through the appropriate port, after which the image will be broadcast on the screen. Despite the relative simplicity of the procedure, a number of problems may arise immediately, even after a successful connection. If the monitor goes off while the computer is running, many users may complain that this is due to its malfunction. In fact, this is not always the case, and below we will look at the main reasons why the monitor turns off during operation system unit.
Signal loss due to faulty cable or connector
The most common reason why the monitor turns off for a while while the computer is running is faulty cable. IN in this case you need to check the condition of the cable itself, which transmits information from the computer to the monitor. Most often, a DVI or HDMI connector in the computer case is used to output images. Make sure the cable is inserted firmly if we're talking about about DVI, it must be tightened, otherwise the connection will not be reliable.
If damage or a poor cable connection cannot be identified, it is recommended to try using another port for connection in the system unit; most often there are several such ports. Also try to get a cable that is definitely not a problem, and connect the monitor to the system unit through it.
The monitor turns off due to problems with the video card
In a computer, the video card is responsible for displaying images on the monitor. Its malfunction can cause the monitor screen to go dark while the system unit is running. You can make sure that the problem is not related to the video card by connecting the computer to another monitor or, for example, to a TV. If the image is displayed on it without problems, then the option with faulty video card can be brushed aside.
Most often, a video card malfunction, which can lead to temporary interruptions in the output signal, is associated with overheating. The base cooler of a video card is not always enough to cool the chip on it, especially if the video accelerator is . Check the video card temperature using special applications, making sure she doesn't go beyond .
It is worth noting: If the problem with the monitor turning off when the system unit is running is due to overheating of the video card, it may appear, for example, only when running resource-intensive games or programs.
Monitor turns off due to bad memory modules
Another common problem that can cause a monitor to temporarily turn off is the failure of random access memory or its work with errors. To make sure that this problem does not exist or does not exist, it is recommended using Windows or third party applications. Even if one of several RAM modules is faulty, this can cause the monitor to spontaneously turn off while the system unit is operating.
RAM modules cannot be repaired, and if the test reveals problems in the operation of one or more of them, you will need to purchase new RAM sticks in their place.
Monitor malfunction
If the monitor goes out while the system unit is running, it cannot be ruled out that there are some problems with it. Most monitors have protection that automatically turns off the screen if there is a risk of overheating. It is not possible to check the temperature of the monitor using diagnostic tools, so the only option is to “touch” to determine whether it is too hot. If your monitor is overheating, you may need to place it in a more ventilated place in the room or, for example, move it further away from the wall.
The monitor can also turn off automatically if it is working in a room with high humidity. In such a situation, you need to move the monitor to a room with normal humidity and let it stand for some time without connecting to the network. During this time, the settled moisture should evaporate, and when working in a normal environment, the monitor will no longer go out if corrosion has not yet formed.

The only thing is, in this case, cables and ports can be damaged if you connect and disconnect them too often, or do it not always carefully. In this case, we can offer two effective solutions to turn off the monitor without unplugging its cables.
Standard Windows tools
Mirror reflection
If you want to turn off your monitor simply because you don't need the extended desktop for a short period of time, you can simply mirror your displays. As a result, you will get a result in which both the internal and external displays will show you the same image. There is no difference which display will be called primary and which will be secondary. All open applications will be reflected equally on both screens.
To mirror your screens, press the keyboard shortcut "Windows + P". In the menu that appears "Project" There will be four options on the right side of the screen sharing two monitors. Select an option "Repetitive" to simultaneously display the same image on two monitors at once. Using repeated keyboard shortcuts "Windows + P" you will be able to switch between the proposed options collaboration monitors or use mouse control to select the desired option. This method will work for operating systems "Windows 7" and higher.
When you decide to expand the image to two screens again, "Windows" will remember which display was the main one and which one was the secondary one.
Turn off the selected screen
If you want to turn off the monitor for more long time or for any other reason, you can use other options standard application for working with monitors "Windows". You have the option to temporarily disable the image feed to any monitor of your choice, and only work on one of them, while the other will be turned off.
To turn off the monitor, press the keyboard shortcut "Windows + P". From the pop-up menu on the right side of the screen, you can select the desired option turn off the monitor:
"Computer screen only"– this option turns off the second monitor and leaves the main screen of your computer;
"Second screen only"– this option accordingly turns off the main screen of your computer and transmits the signal only to the second monitor.
According to your requirements and time need, select the desired option and activate it using the keyboard shortcut "Windows + P" or using the mouse.
When you need to share two monitors again or need an extended desktop, you can use the latter option to display images on two screens. Using a keyboard shortcut "Windows + P" call popup menu "Project" and activate the option "Expand".
The dual monitor display will resume.
Using third party programs
If use standard tool "Windows" is not enough for you, then consider using the program "Multi Monitor Tool". This free utility from company "Nirsoft", which allows you to control multiple displays. It has quite a lot of functions, including the ability to deactivate or complete shutdown any display. This tool only works when you have two or more displays.
Run "Multi Monitor Tool" and from the list of connected displays displayed on it, select your external monitor. Right click on it and select "Disable selected monitors" or « Turn Off Monitors". This option only applies to the monitor you select. To turn your monitor back on, right-click on it again and select Settings "Enable selected monitors" or "Turn On Monitors".
This method has a slight inconvenience: when you turn on or off an external monitor using the tool "Multi Monitor Tool", then the service "Windows" doesn't remember which one was your primary monitor and which one was your secondary monitor. The monitor you connect will always be accepted as a secondary monitor.
To fix this you will have to go to the application "Options" V "Windows 10", and in the section "System" in the tab "Display" Reinstall the primary and secondary monitors. But performing such a procedure every time is not very convenient. Instead, you can save the current monitor configuration and load it after connecting a second monitor. All yours own settings display will return immediately after turning off the external monitor.
Before saving your current monitor configuration, configure your displays exactly how you like them. Then open "Multi Monitor Tool", in the main menu bar, click section "File" and select a tab “Save monitor configuration”. Enter a name in the window configuration file and press the button "Save". To load a saved monitor configuration, go to "File" main menu and select tab "Load monitor configuration".

Similar settings in Windows 10 are available in both the Control Panel and Settings options. The shortest path to settings is through the “Start” button - by right-clicking from context menu select the item “Power management”. In past Windows versions In the “Control Panel” you need to go to the “System and Security” category, then “Power Options” and “Configure the power plan”.
There may be several schemes, depending on the device. For example, for laptop users it will be important to use one power supply scheme when connected to an outlet, and another when operating from the built-in battery. Each of them can be configured independently of each other.
Setting the display timeout
For each scheme, you can separately configure the time to turn off the display and put the computer into sleep mode. Both options will work after the specified time if you do not enter anything from the keyboard or use the mouse. From the drop-down lists, you can select values from one minute to five hours, or specify the “Never” option, if the operating system you are not satisfied.
Also in the advanced options, you may need the very bottom option - “Multimedia Options”. Its second item, “When playing a video,” may be set to “Optimize power saving,” which may cause the screen to turn off while watching a video. Select "Optimize video quality" to prevent this from happening.
What is convenient in the window for working with additional parameters– here at the top you can select any of the created power supply schemes from the drop-down list and configure each of them without moving from one window to another.
