Positioning your projector

16

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 

 and find the closest match to your measurement in the 

average distance from screen column labelled 

. This is the 

projection distance.

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 

 value. This will determine the final placement of the screen in relation to the 

horizontal plane of the projector.

For example, if you need a 16:9 screen to project a 16:9 picture and your measured 
projection distance is 1.5 m (1500 mm), please refer to Table A1 on page 

. The closest 

match in the 

 column is 1623 mm. Looking across this row shows 

that a 150'' (about 3.8 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 

 for details.
