How to determine the position of the projector for a given
screen size
1.
Select your screen size.
2.
Refer to the table on page
columns labelled
find the corresponding average distance from screen value in the column labelled
"Average". This is the projection distance.
3.
On that same row, look across to the right column and make note of the
offset (mm)"
projector in 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 average projection distance is 4710 mm
and with a vertical offset of 513 mm.
How to determine the recommended screen size for a
given distance
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
average distance from screen column labelled "Average". Check that your measured
distance is between the min and max distances listed on either side of the average
distance value.
3.
Using this value, look across that row to the left to find the corresponding
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
offset (mm)"
the horizontal plane of the projector.
For example, if your measured projection distance was 4.0 m (4000 mm), the closest match
in the
"Average"
column is 3920 mm. Looking across this row shows that a 100-inch 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
page 24
for details.

and find the closest match to your screen size in the left
"Screen
size". Using this value, look across this row to the right to
value. This will determine the final vertical offset placement of the

and find the closest match to your measurement in the
value. This will determine the final placement of the screen in relation to
