Solutions to computer monitor ripple 1;
There is nothing wrong with the refresh rate of LCD, that is, 60hz. It is useless to raise or lower it, so rule this out.
So you can switch to another host and see if it's the monitor. I mean, there's nothing wrong with the monitor, so the problem lies in the host computer.
There is also the driver problem. Remember to try updating the driver. Even with a better computer and the wrong driver, the video will look a little unstable and the image will be short-tempered. When the driver is updated, the effect will be obvious and many details will be perfect, so it is possible that the wrong driver caused the water ripple.
Water ripples are caused by host problems, usually for the following reasons. Is there something wrong with the graphics card? Try another one. The reason why my monitor has ripples is that there is something wrong with the graphics card.
As for the problem of the influence of electromagnetic field mentioned on the Internet, I personally think it can be ignored, because all the electronic products produced in recent years are designed with anti-magnetic ability, and a few wires or components can cause water ripples. I wonder how old your equipment is.
The Solution of Computer Monitor Ripple II:
Software problems:
There is no driver installed for the graphics card. In fact, even if there is no driver, the display will display each color correctly, so that the meta color will not be lost, but this problem may occur if the driver is installed incorrectly. For example, the graphics card type and driver type are inconsistent, and the version is inconsistent. This problem can be solved simply by uninstalling and reinstalling the original graphics card driver.
The way to uninstall the driver is: right-click my computer? Attribute? Right-click to uninstall the hardware device manager display card. The method to detect whether there is a problem with the graphics card driver is simple: Take Windows XP as an example. If the red logo on XP can be displayed correctly when booting into the scrolling waiting screen, but it cannot be displayed after entering the system, it proves that the graphics card driver is incorrect.
Monitor problem:
Monitor hardware failure. There are many reasons for the hardware problems of the display, such as the aging of the picture tube, circuit oxidation caused by humid environment, static electricity and so on. , which will lead to abnormal color display. According to different reasons, different methods can be taken, such as putting the monitor in a ventilated place (many people like to cover the monitor with a piece of cloth to prevent dust. Here a reminder, use a special dust cover to prevent dust, otherwise it may lead to poor ventilation and heat dissipation of the monitor).
Graphics card problem:
The display problem is the most common problem. For example, the card slot is not in close contact, the graphics card is overheated, and there are problems with the wiring and components of the graphics card. For the problem that the card slot is not tight, you can pull it out and insert it again. Sometimes it may be because there is more dust. You need to clean the slot here, and use tools such as rubber to clean the graphics card. For the problem of overheating of the graphics card, you can install a small fan on it or put the chassis in a ventilated place. The abnormal color caused by the overheating of the graphics card is often normal when it is first turned on, and it begins to fade after a period of use.
Wiring problems:
Connecting cable between monitor and graphics card. All the color information on the graphics card is often transmitted to the display through the data line. If something goes wrong here, it will also cause three colors to be missing or abnormal. So you can consider trying another thread.
Line interface pin problem:
This is my problem. The lack of red on the monitor has been bothering me for a long time. I have used all the above methods and failed to solve them. When chatting in the group for the last time, Comrade Laotian asked me to see if the pin at the interface of the graphics card was broken. I unplugged the data cable and checked it. Sure enough, one of the needles was bent badly and did not insert the pinhole. Later, I came straight with tweezers and found that the color of the display was all normal, and the missing red came back.
