For example, if you are using an 120-inch screen, the recommended projection distance is
1481 mm and the vertical offset is 137 mm.

This method can be used for situations where you have purchased this projector and would
like to know what screen size will fit in your room.
The maximum screen size is limited by the physical space available in your room.
1.
Measure the distance between the projector and where you want to position the
screen. This is the projection distance.
2.
Refer to the table on page
17
and find the closest match to your measurement in the
average distance from screen column labelled
"Distance from Screen in mm"
. This is
the projection distance.
3.
Using this value, look across that row to the left to find the corresponding
"Screen
Size"
listed in that row. That is the projected image size of the projector at that
projection distance.
4.
On that same row, look across to the right column and make note of the
"Vertical
offset in mm"
value. This will determine the final placement of the screen in relation to
the horizontal plane of the projector.
For example, if your measured projection distance is 1.5 m (1500 mm), the closest match in
the
"Distance from Screen in mm"
column is 1481 mm. Looking across this row shows that a
120'' (about 3.0 m) screen is required.
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 keystone" on
page 28
for details.
