Epson PowerLite Home Cinema 3020plus User Manual page 12

Keep the projector level and place it at a height so its lens is even with the top or the bottom
of the screen and is centered horizontally. If this isn't possible, use the horizontal keystone
slider and vertical keystone buttons to adjust the image (see page 23).
Note: Image quality is reduced if keystone correction is used. For the best possible image quality,
avoid using keystone correction.
The size of the image is determined by the distance from the projector's lens to the screen.
Depending on your display settings and how you use the zoom ring, the actual size may differ.
Use these tables as a guide for projector placement:
