Source-checked About 10 minutes
Answer
Check the monitor, cable and input first, select the correct Windows display mode, then update or reinstall the display driver if Windows still cannot detect it.
Rule out the monitor and cable
Power on the monitor, select the correct input, reseat both cable ends, then test another cable, port or computer.
Select a display mode
Press Windows + P and choose Extend or Duplicate. In Settings > System > Display, select Multiple displays and Detect if that control is available.
Reset and update graphics
Press Windows + Ctrl + Shift + B once. Install Windows updates and the display driver from Windows Update or the PC or GPU manufacturer.
Confirm the monitor and display mode persist
Restart Windows and confirm the monitor appears in Display settings with the intended Extend or Duplicate mode. If it fails on another cable or computer too, continue with the display maker rather than more Windows resets.
