After using the factory cable that came with my Air Pro 2 with my laptop, I tried using the Beam again with the cable, and the Beam display appeared for a second and then disappeared. I used the charging cable that came with the Beam to connect my glasses and it works amazingly. However, I still want to use my factory cable but I do no know what could be causing this issue.
TL;DR
Cable that came with Air Pro 2 works with PC but not with Beam.
It seems like there might be an issue with the stability or looseness of the connection port on the Beam. You can try pressing down firmly on the cable when it is connected to the Beam to see if this stabilizes the display. If pressing it temporarily resolves the issue, it likely indicates a problem with the port. I would recommend contacting customer support for further assistance.
