If you do not want to use the distance table, you can use the following equations to help
determine where to install the projector relative to the screen.

Calculating projection distances
distance from lens to screen = A × width of screen
minimum and maximum distance from screen = B
width of screen = 0.8 × diagonal of screen (for 4:3 screen)
projector lens below bottom of screen = C × width of screen (for 4:3 screen, with projector sitting level)
xp7010/xp7030 series
A = 1.6 to 2.0
B = 1.2 to 10 m (4 to 33 ft)
C = 0.12
