The monitor is one of the main parts of the computer, withoutwhich its use would simply be impossible. The cleaner and more qualitatively the image is displayed on it, the more comfortable and pleasant it is to work at the computer for the user. And the eyes are not as strained as when a bad picture on the display. For these reasons, most users want the flicker of the monitor to be minimal. It depends, first of all, on the device model.
But sometimes you can run intoa nuisance, like ripples on the monitor. And it can happen as with an old device, and with the recently purchased. Usually it appears suddenly and becomes an extremely unpleasant surprise. And it is quite difficult to name any one specific reason why ripples appear on the monitor. So let's look at the most common ones. By the way, do not flatter yourself if you own a laptop. Ripples on a laptop monitor are also common.
So, this problem can arise because of the fact,that automatic gain control does not cope with the signal level that comes from the cable network. Also ripples on the monitor appear due to poor cable contact. It may also be that you have set the resolution too high, as well as the sweep frequency.
In order to eliminate the first cause,it will be necessary to perform a certain adjustment, by means of which it is necessary to extend the range of automatic force regulation. This is done by a potentiometer. This procedure can be done at home, so you do not need to take your device to the workshop.
If the ripples on the monitor are caused by a second cause,most likely, you will need to replace the socket. There is no way to do without a specialist. In the last version, if you do not have indicators any more, you will need to install a special BNS connector. But before that, try switching the color from "PAL" mode to "SECAM" and vice versa. Sometimes this helps, and the image on your display is normalized.
As for liquid crystal monitors,there is also a whole list of possible reasons. This may be an improper operation of the drivers of your video adapter, the video adapter itself, a faulty capacitor, and so on. At home, you can only reinstall the software yourself, and also try to connect the monitor to another device.
If the monitor with another computer is workingnormal, then with it and with the cable all right. The reason is probably the video card. Reinstall the drivers, or even download the latest from the official site. If everything is in the software - the image is normalized. If not, you need to look for a hardware problem.
In order to reveal the true cause of the distortionimages, it is necessary to carry out a thorough inspection, to test the device with special equipment and perform certain restorative work. Therefore, it will be much better if you call a master at home.
