What is the cause of monitor flickering?

The reasons are: 1. The refresh rate is too low. The lower the refresh rate, the easier it is for the screen to flicker. You can set the refresh rate of the monitor to 60Hz or above; 2. Signal interference and external interference. It may cause a flickering screen on the monitor. You can check whether there is a problem with the connection cable between the monitor and the computer or other devices. 3. Monitor hardware problems. There are hardware problems on the monitor itself, which may also cause a flickering screen. You can check whether there are problems with the settings of the monitor. For example, brightness, contrast, etc., as well as updating the graphics card driver. If it still doesn't work, you need to replace the monitor.

Monitor flicker refers to the phenomenon of the monitor screen flickering during normal display. A flickering screen affects the user's viewing experience and may cause visual fatigue.

The main causes of monitor flickering are as follows:

The refresh rate is too low: The refresh rate of the monitor refers to how many static images are displayed per second. The higher the refresh rate, the smoother the picture and the less obvious the flickering phenomenon. Generally speaking, the monitor's refresh rate should be set to 60Hz or above.

Signal interference: When the monitor receives signals, if it is subject to external interference, it may cause the monitor to flicker.

Monitor hardware problems: There are hardware problems with the monitor itself, which may also cause screen flickering.

The following are common solutions to monitor flickering:

Check the refresh rate: Set the monitor's refresh rate to 60Hz or above.

Check the signal cable: Check whether there is any problem with the connection cable between the monitor and the computer or other devices.

Check monitor settings: Check if there are any problems with the monitor settings, such as brightness, contrast, etc.

Update graphics card driver: Update the graphics card driver to fix possible splash screen issues.

Replace the monitor: If the monitor has hardware problems, the monitor needs to be replaced.

The following are specific instructions for monitor flickering:

The refresh rate is too low: The lower the refresh rate, the more likely the screen will flicker. This is because when the monitor displays an image, it displays half of the image first and then the other half. If the refresh rate is too low, the user's eyes will see the image constantly flickering.

Signal interference: When the monitor receives signals, if it is subject to external interference, it may cause the monitor to flicker. This interference may come from electromagnetic interference, power interference, etc.

Monitor hardware problems: There are hardware problems with the monitor itself, which may also cause screen flickering. This problem may be caused by a fault in the display chip, driver board, etc. of the monitor.

If you encounter the problem of monitor flickering, you can try the above methods to solve it. If it cannot be solved, it is recommended that you contact the manufacturer or after-sales service of the monitor for repair.
