Hey everyone! This is my first post here. I just bought a Viewsonic pj458D and its amazing. When I first turned it on the picture was very clear but the only problem was that it was projected onto my ceiling. I adjusted the legs in the back to extend all the way as to lower the picture, but ended up stacking 3 cd cases underneath those back legs to get the picture where I wanted it (on the wall). Is there a way to adjust this on the projector manually? I played with all the settings but nothing is actually bringing the picture downward. Could it be a misalignment of the lamp or something? I've attached a drawing of what I mean:
