Hi Aprice,
Thank you for your response.
I think concure that it is something they have to live with! However apparently one member of staff has managed to get it working but I need to investigate that more as they are only part-time.
I have had some strange issues with the boards, they do seem a bit tempremental. In some cases they need those Activ Cables which boost the signal, we have had one room where we installed an Activ Cable USB A-B and not issues since. Something to consider?
I am looking at the IIyama boards and have a demo coming on Friday, Might be we go with these in the future. Never had an issue with them in my old school.
Thanks
