Many users often encounter such a problem when the image on the monitor twitches. There can be many reasons why this happens, from the wrong monitor settings to the malfunction of the matrix itself. In today's article, we will analyze the most common causes of this problem, and also tell you how to fix them.
It's all about the cable
The first and perhaps most common reason is a defect in the cable through which the monitor is connected to the computer. Yes, at first glance it might seem that such a trifle as a cable is not capable of causing the image to twitch, but it is not.
Violation of the contacts, kinks on the wire, defects in the manufacture of cables at the factory, etc. - all this can affect the final behavior of the image on the monitor.
To check if the cable is the "culprit" of the malfunction, just connect the monitor through another cord. If the problem goes away, then the cord is defective. If left - you need to "dig" further.
Incorrect setup
The second reason why the image on the monitor is twitching is incorrect settings. Very often, when setting the resolution, many users set a high refresh rate, which ultimately leads to jerking and jerking images. To solve this problem is quite simple - you just need to set the correct frequency.
This is done all simply:
- On the desktop, right-click and select "Nvidia Control Panel" or Ati Catalyst from the context menu. It all depends on which company’s graphics card is installed.
- In the application that opens, you need to find the tab on the left side of the "Display".
- In this tab there is an item "Change Resolution". That's what he needs.
- The paragraph provides the opportunity to set not only the screen resolution, but also to change the refresh rate, which, in fact, needs to be done.
- The frequency is best set in accordance with the technical characteristics of the monitor, that is, if in fact the refresh rate is 75 Hz, then this value must be set.
- Finally, to save the settings, just click on the "Apply" button, which is located below.
After these simple manipulations jerking should disappear.
Overclocking
Another very common reason why the image on the monitor twitches is overclocking. Many beginner overclockers like to experiment with overclocking their video card, increasing the frequency of the memory and the video chip itself. Incorrect and incorrect overclocking always leads to the fact that the image on the monitor begins to behave inappropriately. Various artifacts, freezes, ripples, flickers and, of course, jerking can appear.
To fix the problem in this case is also not difficult. All you need to do is run the program through which the acceleration was carried out, and reset the settings to their original state. If you still want the video card to be overclocked, but without any problems, you will need to tinker with better settings. However, as practice shows, even ideally overclocked video cards can sometimes have problems with the image, so it's better to leave the experiments and use what is.
Graphics card issues
The next problem, why the image on the monitor twitches is a malfunction of the video card itself. And it is not at all necessary that the breakdown touches the graphic chip. To cause jerking, artifacts, flickering, etc., a malfunction of the connector for connection is enough.
To find out for sure whether the connector is involved in the appearance of a malfunction, it is enough to connect the monitor to the video card through another input. For example, if you used the DVI connector all the time, then you should try connecting the monitor via VGA, DisplayPort or HDMI. If the video card has 2 DVI inputs, then you can also connect to the second connector.
The result of the check should be as follows: if during a change the interference, jerking, artifacts, etc. disappeared, then the connector was the reason for everything, but if they remained, then the graphic chip could be the “culprit”.
The chip itself is already much more difficult to check, and perhaps the easiest way to do this is to remove the video card from the computer and test it on another PC, if possible. It may be necessary to resort to the help of friends and acquaintances.
If the video card works without changes on another computer, that is, all kinds of artifacts, jerking, ripples, flickering, etc. remain, then the problem has been identified. In this case, only a specialized repair center can help, where the video card will be carefully examined, once again everyone will be checked and after that they will carry out repairs.
Faulty matrix
Well, the last reason why the image twitches on a laptop monitor or on a regular monitor is a matrix malfunction. If none of the above methods can solve the problem, then with a high degree of probability it can be argued that the malfunction lies in the matrix. Alas, nothing can be done about this. The only thing that can help in this situation is to try to give the monitor or laptop for repair, but, as a rule, it is very unprofitable, especially in the financial part.
Repairing a matrix or its complete replacement is always very expensive, so it takes ten times to think before agreeing to such a step.
