A serial number is a unique identifier assigned incrementally or sequentially to your XGIMI projector. You may need the number when you need repair or when you can’t identify whether it is yours or not.
So, how to get your serial number?
Here are two methods for you.
The 12-digit serial number is usually on the bottom of your projector. You can lift the projector up and see the parameters at the bottom of your projector.
You can find it in system info by means of remote control: System Settings >> System Information >> Serial Number.
