Screen Size and Projection Distance

When using a wide screen (16:9): In case of displaying the 16:9 picture on the whole of the 16:9 screen.
x : Picture (Screen) diagonal size: 40" – 500"
L : Projection distance (ft/m)
L1 : Minimum projection distance (ft/m)
L2 : Maximum projection distance (ft/m)
H : Distance from the lens center to the bottom of the image (in/cm)
Note

Refer to page 16 concerning “Projection distance [L]” and “Distance from the lens center to the bottom of

the image [H]”.

Allow a margin of error in the value in the diagrams above.
