That is just the screen that comes up, not the default or recommended settings (throw, zoom). There are two bullets and a vertical slider, one is for zoom and one is for throw distance.
If you want to see what throw distances work for a given screen size, adjust the screen size measurments at the bottom to what you want your screen to be. It will show you the range of throw, min to max, you can place your projector to achieve that screen size. If you slide the vertical bar up and down, it will tell you if you need more brightness or if your in the desired range.
Or, you can change the bullet to ZOOM, adjust your throw distance to what your thinking at the bottom, and then you'll see the Zoom range at any given throw distance. You normally don't want to be at the max or min of your zoom for placement, it is nice to have some room for adjustment.
Hope this all makes sense.
