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.
Prepare the task and protect the current state
Record the PC and accessory models, Windows and driver versions, connection type, exact error, and whether a known-good comparison works. Avoid generic drivers, broad network resets, registry tweaks, or hardware opening. Begin by confirming this task-specific prerequisite: Power on the monitor, select the correct input, reseat both cable ends, then test another cable, port or computer.
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.
Verify the complete result
Repeat the intended action with a harmless test and confirm this final condition: Press Windows + Ctrl + Shift + B once. Install Windows updates and the display driver from Windows Update or the PC or GPU manufacturer. Reopen the relevant settings, destination, account, device, or application and compare it with the recorded starting state before deleting data, removing a recovery path, or relying on the change.
Use a reversible recovery path
If the result differs, undo only the latest change when possible, keep the original data, account, device configuration, driver, or installer intact, and compare the exact symptom with the linked Microsoft Support guidance. Record the version, time, error, and completed checks before contacting official support.
