Seeing as you guys are regarded as the experts on the ae100 i thought i would ask for your help in this matter . I have an ae100 that i shall be sitting 10 feet away from so with this in mind i have ordered a 72" wide screen (i'm using blackout material atm). I have marked out on the blackout material the size of the screen i have ordered and tried manually to get the picture to fit this size to see how far from the screen i'll have to mount the projector. The distance i get is 3.3m but on projector centrals distance calculator when i type in screen width of 1.83m it says distance from screen should be 2.5m - 3.1m . Am i doing something wrong? Regards Adrenochrome.
