    Cause 1: External interference is caused by strong electromagnetic interference such as sparks and high-frequency electromagnetics placed near the display. If the interference intensity is very large, it will cause white horizontal stripes on the entire screen of the display; if the interference intensity is not large, it will show a serious change in a certain corner of the display. Solution: When these two situations occur, we must first focus on the surrounding of the display use site to eliminate equipment with strong magnetic interference. Under normal circumstances, the problem can be solved. Cause 2: Internal interference The performance of internal interference and external interference is very different. If the internal interference of the display is disturbed, black horizontal stripes will appear on the display screen of the display, which is more serious. Solution: In this case, you can open the case and check if there is any bad contact inside the display, whether there is any problem with the output of the power supply or the output transformer. The third reason is that the monitor has a long service life. If the internal capacitor is too long, the aging will be invalid, and the startup speed will be too slow, the screen will be gray, and the font will be blurred. At this time, as long as the aging capacitor is replaced, the fault can generally be eliminated, but since it is also a relatively high-tech work, it is recommended to send it for repair. Cause 4, improper display resolution setting may also appear serious computer screen streak failure, such failures will generally appear on older machines, if the computer works under Windows, you can press F8 to enter the system’s safe mode, Reset the display mode of the monitor, and generally cancel the fault after restarting.

    The first step is to change the connection between the monitor and the host. If it is normal, it is a problem with the line. In the second step, if the problem persists, try it with another monitor. If it is normal, it is a problem with the monitor. The third step, if not normal, is the problem with the graphics card!

    Check if the computer graphics driver is normal. If it is normal, if the computer screen is still flashing, then the monitor should have The problem is.

    First, there may be a problem with the monitor. Take your monitor to someone else’s machine and see if it is the same flashing stripe. If you don’t flash, you can eliminate the display problem.

    Second, you can take your VGA cable and try it out. If there is no abnormality, you can also exclude the line.

    Three, then check the driver problem. Right click on “My Computer – Device Manager – Display Card, then your driver will pop up under the display card, then you can right-click on the driver and look at the driver’s time. Then you go to the mother to download the driver wizard. After installing the driver wizard, you can open it and upgrade the graphics driver in the driver management (not recommended to upgrade other drivers, it will not be blue screen). After the graphics driver is upgraded, restart.

    In short, use the exclusion method, one by one.

    It is a discrete graphics card to plug the graphics card, it is the integrated graphics card to plug the memory. And uninstall Try to install the video card driver.

    No picture, now it is not sure whether it is the display or the graphics card hardware itself or the reason for the graphics card driver.

    You first uninstall the graphics card driver and reload it once. Try (when buying a video card, there is a matching driver, this is the most suitable for the graphics card, third-party software installation driver can also. Try different versions of the driver to determine the driver version is not the reason.) If it is determined that it is not the driver The reason, then there is a big possibility that the hardware itself (monitor and graphics card) has a problem, this is best to go to the repair shop to check the hardware.

    You can only suggest so much now.

    The main reasons for flashing stripes on computer screens are as follows:

    1, subject to external interference:

    There is a strong electromagnetic interference near the display, such as sparks and high Frequency electromagnetic, etc. If the interference intensity is very large, it will cause white horizontal stripes on the whole screen of the display; if the interference intensity is not large, it will show a serious change in a certain corner of the display.

    Solution:

    There are two In the case, first of all, we must focus on the surrounding of the display use site to eliminate equipment with strong magnetic interference, usually the problem can be solved.

    2, subject to internal interference:

    The performance of internal interference and external interference is very different. If the internal interference of the display is disturbed, black horizontal stripes will appear on the display screen of the display, which is more serious.

    Workaround:

    In this case, you can open the case and check if there is any bad contact inside the display, whether there is any problem with the output of the power supply or the output transformer.

    If it is a flashing streak, it should be a problem with the monitor

    That’s because the monitor is getting wet, just take it out and it’s fine.
