Many PC users often encounter a problem when the image on the monitor doubles. The reasons why this happens can be different, starting with a banal poor connection and ending with hardware failures. In today's article, we will examine in detail all the most common problems that cause double vision on monitors, and also talk about how to deal with malfunctions.
Bad contact
So, the first and perhaps the most common reason why the image on the monitor doubles is the poor contact of the cable with the connector. In fact, this is a fairly common phenomenon, because, one way or another, the cable periodically clings, so the contact is broken. As a result, various artifacts, image distortion, ripples, jerking and double image may appear on the monitor.
If suddenly the image began to double on your monitor, the first thing to do is check if the cable contact for connecting to the computer is broken.
Driver Failure
If everything is in order with the contact, and the image on the monitor is double, then it is quite possible that the cause of the malfunction is a malfunction in the drivers. It is important to understand that this is not only about drivers for video cards, which, of course, also play an important role, but also about drivers for the monitor itself.
Very many modern monitors in their kit, as a rule, have a special disk on which the software for its configuration is located, as well as drivers for more correct operation in the system. And if the software does not always need to be installed, then such a number will not work with the drivers - they are needed 100%, otherwise various problems may occur, for example, image jitter, ripples, color artifacts and, of course, the image on the monitor may double.
What if the problem is with the drivers? Everything is quite simple here: you just need to reinstall them from the original disk that comes with the monitor. If the disk is lost, then a more recent version of the drivers can always be found on the official website of the manufacturer.
It is also highly recommended that you install the new drivers on the video card, since they can also cause a double image. They can also be found on the official websites of chip manufacturers - Nvidia and ATI.
Monitor settings
The next reason why the image on the monitor is doubled is its incorrect settings in the parameters of the monitor itself. Many users, in an effort to achieve good image quality, very often turn to settings and, as always, do not pay attention to what functions they include and what parameters they regulate.
As a result of such manipulations, the image not only does not improve, but even, on the contrary, it gets worse. In just a couple of minutes of incorrect settings, an inexperienced user can make the image blurry, double, trembling, with the wrong color reproduction, etc.
Correcting the problem in this case is also not difficult. You need to go into the monitor settings through a special button, find the "Reset" item there and perform the entire reset to the initial state. Everything is simple!
Video card slot
The next reason why the image on the monitor doubles is the problem with the connector for connecting on the video card itself. At the very beginning, we already talked about poor contact on the connectors, but, besides this, you need to remember that defects can easily appear on the connector itself, as a result of which the picture on the monitor through the cable will already be displayed with various noise, artifacts, ripples, etc. . d.
To find out for sure whether the connector is responsible for the malfunction, you need to check it. As a rule, even the most budget video cards have at least 2 different connectors for connecting a monitor, so all you need to do is connect the monitor to a different input. If the problem has disappeared, then the whole thing is in the connector, if not, then you should dig further.
Graphics card issues
Well, the last reason for doubling the image is problems with the video card itself. If the connection cable and connectors have absolutely nothing to do with it, then it is quite possible that the video card may be the cause of the malfunction. Here you definitely need to check: insert the video card into another PC.
If, according to the results of the check, the image will be doubled on another computer, then with a probability of 99% the video card is to blame, if not, then perhaps the reason lies in one of the points described earlier.
