Okay, I'm new here. After several years of being out of "the game" I had decided to jump back in. I am starting to shop for a projector, my first, and screen. I have decided on the Sanyo Z5, but am so confused by the screen sizing my head is spinning. I will be setting this up for movie viewing only. As far as I can tell I either need a 16:9 or a 1.85:1, draper lists both. On a 16:9 will I have black bars at the tops and bottom? will the image completely fit a 1.85:1 ratio. I have been to projector central and projector people's websites and am just more confused now. One says I need a 52x92 the other another size. I have eight foot ceilings and the first row of seating will be approxiamtely 18ft back from the screen, with the second row about 4 behind that and 3ft from the rear. PC says to mount it 4 ft off the floor which leaves me less than 4 ft high? 96" diagonal? 106"? HELP!!!
