The projector is the correct distance away from the board so it needs no “sliding,” but it is crooked. I can’t locate any adjuster knobs or anything of the sort. Any guidance or links to a video for THIS MODEL would be helpful. This model does not have the “plates” for adjusting that I’ve seen in videos of other models. Thanks!
If no adjustments to the projector or the plate it is mounted on have been made, then the Board or the stand on which the board and projector are mounted may be contributing to the mis-alignment of the image put onto the ActivBoard’s surface. If you have a picture of the stand or system everything is mounted on and a picture of the image displayed by the Projector, that would help clarify what is happening in this case and allow us to research this issue further or suggest further steps to try in this case.
