If you show a projector squarely at the screen or wall it should make a perfect rectangular display. If you shine it upwards the top of the display will become wider than the bottom, making a trapaziodal shape. It looks kind of like this: .------------ . ..\ .your../.. ...\ ..pix../... ....------- .... This can easily happen when the projector is sitting on a desk, and it must be aimed upwards for the room to see it. This effect is called "keystoning". It is named from the stone at the top of a masonry arch which has this shape. Manufacturers have included built in controls that allow you to adjust the image to compensate for this effect. So when aimed up, you adjust the "keystone" so that the top becomes narrower, making the image rectangular again, with the sides nicely parallel.
