Short Throw Vertical Keystone Correction

Countering the trapezoid effect when the projector must be placed off-center (such as placement on top of a table) vertical keystone adjusts the image for a perfect squared image. Keystone correction makes it seemless to project ideally aligned images from a variety of locations.
