The solution is 1-2, not 3-4-5-6.
1. After the computer is turned off, start the computer again. When the small scroll appears again, we will press and hold the power button to force the computer to turn off.
2. Repeat the above steps for 2-3 times, and the "Select an option" interface will appear. Click the Troubleshooting option.
3. Check the monitor connection: Make sure that the monitor is connected to the computer correctly and the cable is not loose or damaged. Try reseating the cable to ensure a secure connection.
4. Check the resolution setting: If the monitor can't display, it may be because an unsupported resolution is set. You can try to start your computer in safe mode or low resolution mode, and then set the resolution to the standard resolution suitable for your monitor.
5. Update or restore the graphics card driver: Sometimes, the display problem may be related to the graphics card driver. To try to update the graphics card driver, you can go to the graphics card manufacturer official website to download the latest driver and install it according to the instructions. If the problem occurs after the driver was recently updated, you can try to restore the driver to the previous version.
6. Enter Safe Mode and Troubleshooting: You can try to enter Safe Mode, in which only the necessary drivers and system services are loaded. If you can enter safe mode and the screen displays normally, a third-party program or driver may be causing the problem. You can gradually disable startup items and services to determine which program is causing the problem.
