If you have enabled the "enable clone" option on your PC and your second monitor is no longer detected, there are a few things you can try:
Check your cables: Make sure that your cables are properly connected and that they are not damaged.
Restart your PC: Sometimes, restarting your PC can fix the issue.
Disable clone mode: To disable clone mode, right-click on your desktop and select "Display Settings". Under the "Multiple displays" section, select "Extend desktop" instead of "Duplicate desktop".
Update your graphics card drivers: Check if there are any updates available for your graphics card drivers and install them if necessary.
Try a different port: If your PC has multiple ports for connecting monitors, try connecting your second monitor to a different port.
If none of these steps work, you may need to seek further assistance from a technical support professional.
