I am taking over for a teacher who has a promethean proACTIV board and a LC-XB22 projector. I do not have any previous information on the registration of the board. I was given a laptop with activstudio on it, but it no longer works. I downloaded activinspire and activmanager on my personal HP. When I connect the VGA cable and start up the laptop and projector the image from the laptop's startup displays on the board. Then the projection goes blue. My computer does not show any hardware connection. I have also tried connecting the usb through a serial port and no connection is detected. Any advice for troubleshooting?
