Having a lot of issues with this setup. Sometimes the USB won’t recognize and sometimes the projector will not display. It is very random. Has anyone else had this issue?
The issue sounds like it is being caused by the cabling. Can you please confirm the model of ActivBoard and projector you have?
Also can you please confirm how the projector and ActivBoard are connected, do the cables go through a face plate/wallbox?
What happens if you try a direct connection?
Finally can you please ensure you have the very latest driver installed (5.14.21). This can be downloaded from the below link:
