What if the computer screen flashes or the computer screen jitter occurs? Generally, the screen on a new computer is flickering or jitters. If the display fails, we should first eliminate the following possibilities:

The check method is as follows: Right-click the blank area on our computer desktop-properties-settings-advanced-Monitor, for example:
650) This. width = 650; "src =" http: // 183.61.143.148/group1/m00/02/3 F/tz2PlFQ029jjgA7pAAIu_7SO-s0308.png "/>
650) This. width = 650; "src =" http: // 183.61.143.148/group1/m00/02/3 F/tz2PlFQ02-PzscQ7AAFulluKlak584.png "/>
We can see that the refresh frequency of the display is set to "60", which is the reason for the constant jitter of the display screen. Set the new frequency to "75" or above, and click OK to return to the desktop. Some laptops only have a value of 60Hz, so you do not need to set it. In addition, setting too high may cause damage to the display. Therefore, you can try to change it. If you haven't touched it before, you can directly select the default value.
2. Check whether the graphics card driver is correct
Sometimes when we enter the display refresh frequency on the computer, we find that there is no refresh frequency to choose from. This is because the driver of the front video card is incorrect or too old. This problem may occur when you purchase a computer that was earlier than purchased. You can check and install the driver of the latest version on your own instead of using the drive on the disc that was used when you purchased the computer.
Iii. Interference around the computer

Try not to bring the display near a large electrical product. You can also restart the computer monitor to check whether the current display has the automatic degaussing function when it is enabled.
Iv. Display hardware problems or power problems
The above situations are rare. The most common problems are hardware problems, such as the amount of data lines that the monitor and host are connected, in addition, the display power supply only focuses on the troubleshooting objects. Among the problems of computer screen jitter and computer screen flickering, the most common problems encountered by computer screen flickering are display power supply, there are also many cases where the display is aging and the display is faulty. In addition to the magnetic field or electric field interference, the most common problem is the aging fault of the display. The solution is to take professional repair points for repair.
