Newbie here. When I move into my new place I'm allowed to set up my first projector and screen in living room as long as "it looks tidy" (not on ceiling/wall). Here's my current rough plan; http://i.imgur.com/2i3KDQW.png Because the projector isn't exactly room central I'd need one with horizontal lens shift right? Around how much lens shift do you think I'd be looking for at a position like that? Was looking at something like the Epson EH-TW6600 I'll also be putting 5.1 in the room. Screen will be 100" or 120", whichever suits best. Is this setup logical / practical?
