A: The blue image is where the white background is. It is the part of the screen that the projected picture will be projected to. Overall the screen does a pretty good job and if you live in an apartment and don't want to be hanging a screen from the ceiling or wall which most apartments don't want or allow you to do, or you wish to use the projector in another room, or outdoors I believe the screen will serve your purpose. It also allows the screen to be retracted and is a hard shell case and light enough that makes it portable enough to move from one area to another, which really makes it even more useful.
A: Yes, you can adjust the amount of black on the bottom of the screen.
