The projector is now projecting the entire screen to the board. It seems like what is appearing on the screen is in “wide screen” because there is a thick line blocked off at the top and bottom and on each side. How can the projector project the entire screen?
It seems that the resolution on your computer or the aspect ratio on the projector need to be adjusted.
In order to assist you with that, please visit http://www.prometheankb.com and search for 10418. This is an article which explains which resolution you need to be using according to the ActivBoard you have.
Please let us know if you need more information.
