For example, If you are using the MX766 and a 150-inch screen, the projection distance is 7.14 m and with a vertical offset of 34.3 m.

If you are using the MX766 and your measured projection distance is 4.0 m (4000 mm), the closest match in the "Distance from screen (m)" column is 3.79 m. Looking across this row showsthat a 80'' (about 2.0 m) screen is required.
