OS: Windows Pro 21H2 (updated)
Hello, I'm the tech lead of a high school lab and of the intreractive whiteboards (with connected PC TravelMate 214) of eight classrooms.
The whiteboard model are identical: Promethean Activeboard Touch 78 (all have a video projector) that is connected to the Travelmate with an USB cable (three m length).
Four out of eigth TravelMate cannot detect correctly the ActiveBoard!
It means that after having installed the applications to use the whiteboard, it is impossible to calibrate it (that is when drawing with the interactive pen, the line/point is not correctly aligned with the pen tip).
