I am setting up a home theater in my living room. I completely remodeled my house after a fire and I thought this would be a good time to set up the theater. I have a in-wall speaker system set up with JBL Northridge series speakers and a 12" powered sub. I have what I call a "tray ceiling" vaulted ceiling in the living room. I also have wood floors so it wis probably going to be loud in there. Anyway I am thinking about mounting a projector in the vaulted ceiling and projecting it against the opposite wall. I'll try and include a picture. I am looking at a Optoma H76 right now. I would like remote zoom and focus and the projector would have to have capabilities to adjust out keystone images. What do you guys know about Optoma projectors? How do you insert a picture? I tried and don't know how.
