Switch on the projector and make sure it is fully powered up.

On the remote control of the projector, look for a dedicated button labelled "Menu" or an icon that looks like a cogwheel or a setting. Press this button to enter the settings menu.

Use the arrow keys on the remote control to navigate to the section or option labelled "System settings", "Settings" or similar. Press the "Enter" or "OK" button to access it.

Within the system settings, look for an option such as "Reset to factory settings", "Factory Reset" or similar. Highlight this option and press the "Enter" or "OK" button to continue.

Depending on the model of the Xgimi Horizon Pro projector, you may receive a confirmation message. If so, select "Yes" or "OK" to continue.

The projector will now reset to factory settings. The process may take a few minutes. During this time, do not switch off the projector or disconnect it from the power supply.

Once the reset process is complete, the projector will restart automatically and will now be in factory settings.
