For many years, various discussions on one fairly common problem have not faded. Every now and then on the forums, users are interested in what to do when the monitor goes blank. Moreover, such questions arise quite often. Some are even immediately interested in how to repair a monitor. But it is fair to say that it is not worth rushing to repair. The problem may be with custom installations. But first things first.
So why does the monitor go blank? It is impossible to give a definite answer to this question. After all, there are many different features that lead to such consequences. To establish the truth, sometimes you have to test many components. In this case, one cannot do without the help of specialized specialists. Fortunately, such measures need not always be taken. Therefore, now I will give some recommendations that may help identify the cause and even restore the normal operation of your device.
When your monitor goes blank, you must immediately exclude the corresponding settings. Indeed, if the user is inexperienced and only comprehends the basics of working with a computer, he does not always know that the computer can automatically turn off the display during long periods of inactivity. To adjust the time after which the screen will turn off, or simply deactivate this option, follow the steps below.
Right-click on any area of the desktop, in the context menu, launch the "Properties" section. When the corresponding window appears, you need to go to the screensaver settings, where you need to press the power button. Find there the item that will be responsible for turning off the screen, and set the right time in it, after which you would like to turn off the display, or completely abandon this option.
If your monitor goes blank during active work with the device, here is not so simple. This, of course, does not bode well, and also speaks more seriously about the problems than the previous one. I also had problems with the monitor. After starting the computer, I could work for about fifteen minutes, after which the screen went blank. If games were launched that require significant video resources, it went out even earlier. It turned out that in my LCD monitor the matrix was out of order, which was replaced at the service center.
Although the same symptoms are observed with other hardware problems. For example, a monitor may fade if your video adapter stops working properly. This can also be indicated by an unexpected reboot of the system without an appropriate command on your part. As a rule, in this case, replacement of this element of the computer is required.
But you can try to do something yourself. It happens that the video card may be working, but exhibit the same symptoms. In this case, try swaying it in the slot. Some contact may go away and this will cause your problem. It is also worth trying to eliminate this by disconnecting and then attaching the cord that runs from the video adapter to the monitor. You can also reinstall the drivers.
