Thanks for posting. You can find alignment guides for most of our projectors by going to http://www.PrometheanKB.com. If you cannot find what you are looking for them please let us know what your model of projector is and we can assist you further.
I got a problem I hooked up projector and picture is clear but the projector is facing upward and picture look like its not squared off but when I move projector down its squared off but it to low on wall. The question is do I need to relocate the projector back more.
If you could provide some photos of the projector with no source connected and how this is displaying on the ActivBoard this would help. Please also let us know the ActivBoard model and projector model (not serial number).
We would always recommend aligning the image with no source connected and ensuring that no keystone or digital zoom is set. Should the picture change once a source is being displayed then you can adjust this on the computer.
