What about computer screen jitter and flicker? Professionals help you

After the friend bought the computer, she was very happy, but the computer screen flickered when the computer was turned on, and the computer screen was shaking! It was very expensive to read the words on the screen. The search results were answered. After the stable version of the graphics card driver was reinstalled, the problem was solved. . The screen flickering on the computer screen is not a problem we often encounter, but it will be very confusing after encountering it. It is very uncomfortable to watch, and it is easy to get eye diseases. If you encounter such a problem, you should solve it as soon as possible. Or ask a professional to give a good solution, this article is a professional solution.

There are several possibilities for computer screen jitter:

1. The display refresh rate is set too low. When the refresh rate of the display is set lower than 75Hz, the screen will appear jittery and flickering, and the refresh rate will be adjusted appropriately. For example, if it is set higher than 85Hz, the phenomenon of screen jitter will not appear again. The landlord, your monitor is shaking after booting, normal after entering the system, certainly not for this reason.

2. The power transformer is too close to the display and the chassis. When the power transformer is working, it will cause large electromagnetic interference, which will cause screen jitter. Keeping the power transformer away from the chassis and display can solve the problem. This is also unlikely because the display of the landlord can automatically return to normal.

3. The power supply or power supply unit has aged. Many of the components used in computer power supply are poor in workmanship and materials. It is easy to cause the computer's circuit to be poor or the power supply capacity can't keep up. When the system is busy, the display will especially appear on the screen. When the computer's power supply starts to age, it is also likely to cause the same problem. The landlord, yours may be the case, check to see if there is a capacitor aging condition in the power supply.

4, the speaker is placed too close to the display. The magnetic field effect of the speaker will interfere with the normal operation of the display, causing the display to produce magnetic interference such as screen jitter and crosstalk. This should not be because your monitor will return to normal after entering the system.

5, In addition, viruses, poor display card contact, these may cause the display image to shake.

6, also, CRT display will automatically degaussing action when starting, the performance of the display screen jitter, but under normal circumstances will soon return to normal, probably only takes 3 seconds.

Summary: Your monitor is most likely caused by the aging of the power supply. It may be the circuit part of the monitor, or it may be the circuit part of the motherboard or graphics card. You can use the exchange method to check the host problem. Still a display problem. Previous12Next page Total 2 pages
