I just mounted my 1031q on a custom celiing mount very similiar to Krynos DIY ceiling mount:

Heres my problem. I measured my projection wall and marked dead center. I also marked dead center on the ceiling where the PJ is hanging. After hanging the PJ we adjusted it so that its centered with the ceilling mark. After leveling, I projected a DVD through my HTPC. However the screen is off-center on the projection wall a couple inches.
My question is how can i tell if the front of my PJ is dead on straight and parallel with the projection wall?
Im pretty certain my mount is straight ( i measured several times, and again after i put up the mount) however, the ubolts could cause some angling one way or the other of the PJ. If i get up there and angle the projector by hand, just a slight movement really moves the picture.
One thing i didnt do is try the internal crosshath or grid pattern. it could be that my extron box is shifting the image out of my HTPC. Ill check that tonight. However, if that is still off then i know its either my PJ or the convergence is wacked so that i need to horizontally move all 3 over to center the picture.
