Epson PowerLite 1221 User Manual

Image Shape
You can project an evenly rectangular image by placing the projector directly in front of the center of the
screen and keeping it level. If you place the projector at an angle to the screen, or tilted up or down, or off
to the side, you may need to correct the image shape for the best display quality.
When you turn on automatic keystone correction in your projector's Settings menu, your projector
automatically corrects vertical keystone effects when you reposition the projector.
