I had to move the projector to front to reduce the size of the picture. So it is like hit and trial to be accurate if you already have fixed screen size. If you are presenting on wall, then it becomes easy.
Sorry, there was a problem. Please try again later.There are several websites can help you calculate what the exact mounting parameter you will use. Generally speaking, 8-12 feet distance should well project on a 90"~135" screen. Once you decide the screen size and hanging position, then you can calculate back the projector location and see if this projector is suitable for you.
