How to determine the position of the projector for a given
screen size
1.
Select your screen size.
2.
Refer to the table and find the closest match to your screen size in the left columns

. Using this value, look across this row to the right to
find the corresponding average distance from screen value in the column labelled
. This is the projection
distance.
3.
On that same row, look across to the right column and make note of the vertical offset
value. This will determine the final vertical offset placement of the projector in
relation to the edge of the screen.

relation to the edge of the screen.
4.
The recommended position for the projector is aligned perpendicular to the
horizontal center of the screen, at the distance from the screen determined in step 2
above, and offset by the value determined in step 3 above.

For example, if you are using a 120 inch screen, the recommended projection distance is
4800 mm and with a vertical offset of 183 mm.

If you place the projector in a different position (to that recommended), you will have to tilt
it down or up to center the picture on the screen. In these situations, some picture distortion
will occur. Use the Keystone function to correct the distortion. See
