Positioning your projector

For example, if you have a 16:9-aspect-ratio screen and your measured projection

distance was 4.5 m (450 cm), please refer to "The screen aspect ratio is 16:9 and the

projected picture is 16:9". The closest match in the "Average" column is 455 cm. Looking

across this row shows that a 100-inch screen is required.

Checking the min and max projection distance values in the columns of "Projection

distance <D> [cm]" on page 14 indicates that the 4.5 m measured projection distance

will also fit the 90 and 110-inch size screens. The projector can be adjusted (using the

zoom control) to display on these different screen sizes at the projection distance. Be

aware that these different screens have different vertical offset values.

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 22 for details.
