WhiteBoard Projected Colours
We have a new Promethean Board that was installed last summer and the teacher is complaining about the displayed colours (obviously a projector issue rather than the board). I went to her room to check and she is quite right, the worst being that the colour red is just displayed as black on the board, green is brown.
I have done factory reset on the projector and messed about with most of the obvious setting without any luck.
Do you have any advice, the projected image also appears duller than the other boards fitted at the same time. I have messed with the brightness settings too.
