3.On that same row, look across to the right column and make note of the "Vertical offset (mm)" value. This will determine the final vertical offset placement of the 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
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 17 and find the closest match to your measurement in the 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 "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 (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 4.8 m (4800 mm), the closest match in the "Average" column is 5046 mm. Looking across this row shows that a 250'' (about 6.35 m) screen is required.
Checking the min and max projection distance values on the columns of "Distance from screen (mm)" indicates that the 4.8 m measured projection distance will fit the 220'' size screen. The projector can be adjusted (using the zoom control) to display on this screen size. Be aware that different screens have different vertical offset values.
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 25 for details.
