The HUAWEI monitor screen flickers or the display is erratic

Problem

The monitor screen flickers or the display is erratic. When the signal source is changed, the screen turns black or flickers.

Cause

1. The cable connection is faulty.
2. The screen is cracked.
3. The signal input of the computer is faulty.
4. There are other app issues or compatibility issues.

Solution

1. Make sure that you are using the cable that comes with the device and that the cable is properly connected. Try reconnecting the monitor and the computer. If the problem persists, replace the cable.
2. Check whether the erratic display is caused by cracks in the screen. Power on the device and check if there are smudges, such as liquid leakage in the crack. If so, you are advised to contact Huawei after-sales service hotline or Huawei commercial customer service line for assistance.
3. Connect the monitor with another computer. If the monitor now works properly, the issue lies with the computer. Check whether the computer port is dirty or the pins are poorly connected, or try using other ports on the computer.
4. Update your apps or install compatible apps, optimize settings, or uninstall and reinstall Windows.
   1. If the issue occurs only on a certain app, uninstall and reinstall the app or update the app to its latest version. If the issue persists, contact the customer service of the app vendor.
   2. Optimize the graphics card driver on the computer: If you are using a HUAWEI computer, update the graphics card driver using Huawei PC Manager. If you are using other computers, visit their official websites or contact their customer service for help. Exercise caution when using a third-party app to update drivers, as this may cause unknown compatibility issues.
   3. Update the OS system by referring to Get the latest Windows update.
5. If none of the above solved the problem, take your device and proof of purchase to an authorized Huawei Customer Service Center for further assistance. We will do our best to address your needs.
