What does this Error symbol mean

What does this error mean. Projector won’t display Home Screen. This is the only image I get since I unboxed it yesterday!

Hi @HannahBrown may I ask which product you have? Is it a PicoPix Max One?

This symbol means: “please plug something in” to the HDMI or USB-C video port. So just plug something in. The Max One doesn’t have any internal system, you must plug an external video input.
