Hey guys, I am using an Optoma H78DC3 projector with a 119" HD Da-Lite Videospectra screen with a gain of 1.5. I have bought the universal mount and am planning to buy some sort of extention. There will be 2 rows of seating, starting at about 15 ft from the screen. the room is only 13.5' wide, so its a narrow viewing angle. and the ceinling is about 10' high.


The calculator says to mount the projector on the ceiling 18.5 ft. from the screen. However, how low does the projector need to come from the ceiling, and how many degrees should it be apprx tilted.


(This may be a dumb question): If we mount the projector upside down, doesn't the image appear inverted?? Do I need to call a specialist to setup my equipment or can I do it myself?


Thanks
