1. Black Screen or No Display First, check if the power cord is properly connected and functioning. Then inspect the monitor for any signs of damage, such as a broken power button. Also, check if the computer host is working properly, including restarting the host to rule out possible software issues. If the problem still persists, consider whether the graphics card is faulty and replace it if necessary. 2. Abnormal Color Display Check if the color settings in the computer system are correct. If they are set correctly but the problem persists, it may be a sign that the monitor has aged or has hardware issues, and replacing the monitor may be necessary. 3. Flickering or Unstable Display Try restarting the host to rule out possible software issues. If the problem persists, check if the power supply is stable. Additionally, it is crucial to check if the graphics driver is up to date and compatible with the operating system. If the problem still cannot be solved, it may be due to internal component damage in the monitor. 4. Display Lines or Spots First, check if the connection cable is loose or damaged. If the connection cable is normal, it may be a sign of internal component damage in the monitor, and it is recommended to contact the after-sales service center for repair or replacement.
