How to determine the position of the projector for a given screen size
1.
Select your image size.
2.
Refer to the table and find the closest match to your image size in the left columns labeled
size". Using this value, look across this row to the right to find the corresponding average distance
from screen value in the column labeled
distance.
3.
On that same row, look across to the right column and make note of the
determine the final vertical offset placement of the projector in relation to the edge of the image.
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.
<Example>
LV-X310ST: If you are using a 4:3 aspect ratio, 100-inch screen, distance from the screen is 1.23 m and
with a vertical offset of 22.9 cm.
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
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 and find the closest match to your measurement in the distance from the Image size
column. If the min and max values are available on the table, 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
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
