What if the computer screen flashes? The solution of computer screen flickering, ha ha Da, how do you solve it? Well, then I'll simply popularize it for you. I hope I can help you!
I. is the display refresh rate set correctly
The inspection method is: right click "screen resolution" - "advanced settings" - "monitor" in the blank area of our computer desktop.
Screen resolution
Advanced settings
Monitor
It can be seen that the refresh rate of the display is set to; "60", which is the reason for the constant jitter of the display screen. Set the new frequency above "75", and then click OK to return to the desktop. Some laptops only have the value of 60Hz, so there is no need to set it. In addition, if the setting is too high, it is easy to cause damage to the display, so we try to change it. If we haven't moved before, we can directly choose the default.
II. Check whether the graphics card driver is correct
Sometimes when we enter the refresh rate of the computer monitor, we find that there is no refresh rate to choose from. This is caused by the incorrect or old driver of the front graphics card. Computers purchased earlier are prone to this problem. At this time, do not use the driver in the CD when purchasing the computer. You can check and install the latest version of the driver by yourself.
III. whether there is interference around the computer
Observe whether there is strong electric field or strong magnetic field interference around the computer display. The magnetic field interference is very easy to cause the computer screen to shake or flicker. The elimination method is to place the computer in another open place and then observe it. You can also go to another place to get a good computer to test and eliminate it. Try not to put the display near large electrical products. You can also restart the computer monitor. Generally, the current monitor has the function of automatic degaussing during the opening process.
IV. display hardware problem or power supply problem
The above situations are rarely encountered. The most encountered problems are hardware problems, such as the lack of data lines connected between the display and the host, which can be solved by replacement. In addition, the display power supply only focuses on the troubleshooting objects. Among the failures of computer screen jitter and computer screen flicker, the most encountered problems of computer screen flicker are the problem of display power supply, and many of them are the aging of the display, The display is faulty. In addition to the interference of magnetic field or electric field, the most common display jitter is the aging fault of the display. The solution is to take it to a professional maintenance point for maintenance. Generally, new monitors can be guaranteed or replaced. It is rare for new monitors to be caused by hardware problems.
