Thanks for posting on the Support Community.
Has the ActivBoard and projector ever been working previously or is this a newly installed board?
You will need to have a USB cable attached to the ActivBoard and the computer to get interactive (the red flame should change to white).
Is the projector a Promethean branded projector? If possible could you provide the model number (excluding serial number).
You will most likely have the VGA cable plugging from your computer to a wallbox or connectivity panel, please ensure if this is plugged in to a VGA 1 or 2 port that this is also reflected on the projectors VGA 1 or 2 input and the correct source is chosen.
I hope this helps
