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 27).
Note: Image quality is reduced if keystone correction is used. For the best possible image quality, avoid using keystone correction.

Diagonal image size
Offset refers to distance from bottom of image to center of lens.
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:
