Once you turn on your computer, and everything seems to be fine, the system unit is running, but the monitor screen does not work. What to do in this situation and how to solve the problem. we will tell you in our article.
First, a few words about the diagnosis. It is very important in this case to determine the nature of the problem. If the monitor does not react at all when the computer is turned on, this means that it does not receive a signal from the computer, if the monitor responds to the computer turning on, the indicator shows communication with it, then the problem is either in the video card or with the monitor itself. If the system itself does not boot, and the BIOS does not appear on the monitor, the reason is the computer itself.
After such an analysis, proceed to search for the reasons for the lack of an image on the monitor and solve this problem.
Why does the monitor not work?
Next, experts at Masterservis24.ru will tell you about the most common reasons why the monitor does not turn on or if there is no image on the monitor.
- Lack of monitor power
First of all, check the power to the monitor. When the monitor is connected to the network. a yellow or red light should be lit on it. Check the plug for connecting the cable to the outlet and connecting the power cable to the monitor itself. You can also try connecting the monitor using a different power cable. If everything is connected and the power light is on, then the problem is not in the power.
Incorrect or poor connection cable
The second most common reason why the computer monitor does not turn on is the incorrectly connected connecting cable between the monitor and the system unit. Check that the cable is connected to that connector, since if you have an integrated video card and with it a discrete one, then the cable from the monitor should be connected to the discrete one, it is usually lower.
Along with this, we also recommend that you check the correct connection to the connector itself, for this, remove and reinsert the connection cable, both in the system unit and in the monitor itself. There is a possibility that the connection cable may fail, so try connecting the monitor to a computer using a different cable.
The reason why the monitor does not work on the computer is a failure in the image settings. This may be due to incorrectly set monitor resolution, frequency, and other settings. To do this, connect the monitor to another connector, or enter through safe mode and reset the monitor.
If you have 2 video cards, then make sure that the integrated video card is disabled in the BIOS settings.
Problems with the graphics driver
Also, drivers can cause a problem with the lack of an image on the monitor. If you previously uninstalled the driver or installed a new one, or updated it, as a result of this, the video card may start to work incorrectly, including the absence of an image on the monitor. To do this, log into the system through safe mode and completely remove the old video card driver and install a new one.
Graphics card issues
A problem with a graphics card can occur not only due to drivers. For example, if you previously cleaned the system unit, then it is possible that you touched the video card, and if you removed it, then you inserted it incorrectly. To do this, turn off the computer, remove the video card and reinsert it.
If the problem is not resolved, or before that you have not performed any robots in the system unit, then try connecting the card to another connector on the motherboard, and if there is an integrated one, connect the monitor to it, having previously pulled out the discrete card to check the monitor itself. It is possible that the video card itself has broken.
We also recommend checking the settings of the monitor itself. In particular, make sure that the type of cable connection used (VGA, DVI or HDMI) is selected in the settings. Also wander through other settings.
It may be that the monitor itself has broken, this also occurs. In this case, do not be very upset, because if the monitor does not turn on, then this is not as bad as in the case of problems with the screen matrix.
In the case when the monitor displays only the BIOS boot, and then does not turn on, while the sound of starting the operating system is reproduced, the problem with the monitor may be in the system itself. Perhaps there was some error or there is a problem in the operation of system files. If before that you installed any programs that change the visual style, then such a conflict can occur. Viruses that block the operation of the operating system itself, as well as the operation of drivers and devices, can lead to such a problem.
When the monitor displays the BIOS load, but after that a black screen appears, and there is no sound to start the OS, then reinstall the system.
If the monitor does not work even after all the steps taken, then try connecting it to a laptop or video player to check its performance. If the monitor works when connected to a video player and does not turn on when working with a computer. then the problem is in the video card or in other computer components. If the monitor does not work when connected to another device, bring it in for repair. You can also try connecting another monitor to a computer or a modern TV, if the image is there, the problem is in your monitor, if not, then look for the problem in the computer components.
We wish you success in solving this problem, and if you did not succeed in solving it, then our experts will help in this.
