Why is my Promethean board not filled with my laptop screen?
I have a PRM-35 Promethean projector hooked to an hp laptop. Last school year all was great. They re-imaged our computers over the summer. I had to download activeinspire and activdriver. Now I have about 9 inches top and bottom on my board that are not filled with my laptop screen. I have tried different settings on the projector but cannot get the board filled.
