Good morning Rob.
Thanks for posting on the forum.
We have a guide on how to align the EST-P1 projector on our knowledge base. Please go to www.PrometheanKB.com and search for article 11104. This article contains a PDF document showing the best way on aligning to get that perfect fit.
I hope this information helps, if you have any questions please do not hesitate to reply.
