Positioning your projector
English
If you place the projector in a different position (to that recommended), you will have to tilt it down or up
to center the image on the screen. In these situations, some image distortion will occur. Use the Keystone
function to correct the distortion. See "Correcting picture distortion" on page 25 for details.
