1. Check the hardware connection: make sure all hardware devices (such as monitor, keyboard, mouse, etc.). ) whether it is connected to the computer correctly and whether the plug is loose or falling off.
2. Restart the computer: Sometimes, the computer problem is temporary, and restarting the computer may solve the patent display problem.
3. Update drivers: Make sure that the drivers of all hardware devices are the latest version. You can update the driver by visiting the official website of the hardware manufacturer or using the driver update tool.
4. Disable startup items: Some software may run automatically at startup and cause conflicts. You can try to disable these startup items by opening Task Manager (press Ctrl+Shift+Esc) and disabling unnecessary programs in the Startup tab.
5. Safe mode startup: Try to start the computer in safe mode, which will disable unnecessary startup items and drivers, thus determining whether the problem is caused by a certain software or driver. In safe mode, if the display problem disappears, it may be caused by third-party software or drivers.
If all the above solutions fail, it is recommended to contact the technical support department of the computer manufacturer or consult a professional for help. They can provide a more accurate solution to solve the patent problem of display.
