What should you do to restore an HP monitor displaying a 'Theft Mode Enabled' message on power-up?

Restoring an HP monitor displaying a 'Theft Mode Enabled' message requires addressing the specific condition of the monitor. The 'Theft Mode Enabled' message indicates that the monitor is in a state that prevents its use without being connected to the original computer it was paired with. This security feature is designed to deter theft by preventing the monitor from functioning with any other source.

By reconnecting the monitor to its original computer, you can disable the Theft Mode. This process typically involves accessing the monitor’s settings on the original computer and disabling the Theft Mode option. Once it is disabled, the monitor can be used with different computers without displaying the theft message.

While resetting to factory settings, using the HP Display Utility, or changing video output settings might address other issues, they will not solve the Theft Mode problem directly. Therefore, reconnecting to the original computer to disable the Theft Mode is the appropriate course of action to restore normal functionality to the monitor.
