After deciding what my budget would be, I am now down to the likes of the Optoma 72i, Z5, themescene etc. attached is a crap drawing of my viewing area. I will keep the telly where it is so the screen will be tight against a wall, distance from top of screen to top of telly is 58 inches, from screen to PJ is 12 feet. I was wondering what I need to take into account here. Considering which PJ`s have better lense shift than others, do I have the PJ ceiling mounted and the throw angled down to the screen?, up to the screen?, level?, or put it on a shelf at just above head height on the wall? Depending on the reccomended position of the PJ, which model would best suite this? Any help would be great.
