MS619ST/MX620ST

The screen aspect ratio is 4:3 and the projected picture is 4:3

For example, if you are using an 120-inch screen, the recommended projection distance is 

2422 mm and the vertical offset is 91 mm.

If your measured projection distance is 3.0 m (3000 mm), the closest match in the 

 column is 3028 mm. Looking across this row shows that a 

150'' (about 3.8 m) screen is required.
