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.Determine the aspect ratio of the screen you need, 16:9 or 4:3? If you need a 16:9 screen, refer to Table A1 (page 17) or Table A2 (page 18). If you need a 4:3 screen, refer to Table B1 (page 19) or Table B2 (page 20) depending on the projected picture aspect ratio you’ve got.

2.Measure the distance between the projector and where you want to position the screen. This is the projection distance.

3.Refer to the table 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.

4.Using this value, look across that row to the left to find the corresponding "Screen Dimensions" listed in that row. That is the projected image size of the projector at that projection distance.

5.On that same row, look across to the right column and make note of the "Vertical Offset" 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 was 4.8 m (4800 mm), please refer to Table A1 on page 17. The closest match in the "Average" column is 4554 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 34 for details.
