Epson ELP-600 User Manual page 45

If the projector cannot be set up so that it is perpendicular to the screen, you can
use the keystone correction function which is described on the following page
to adjust the projected images if the angle of the projector is within a range of
approximately 30 vertically or approximately 10 horizontally from the
perpendicular.
The values given here are for when the image is at the smallest zoom setting
(telephoto). The maximum angles will be smaller if the zoom setting has been
increased in the wide angle direction. Furthermore, if the projector has been
tilted both vertically and horizontally, the maximum adjustable angle will again
be smaller than the maximum angle if the projector had been tilted in only one
direction.
