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 size (diag.) (in/cm): 40" – 500"
L1 : Minimum projection distance (m/ft)
L2 : Maximum projection distance (m/ft)
H1 :
Lower distance from the lens center to the bottom of the image (cm/in)
H2 :
Upper distance from the lens center to the bottom of the image (cm/in)
W :
Distance from the lens center to the center of the image cm/in)
The formula for picture size and projection distance
When using a normal screen (4:3): In case of displaying the 4:3 picture on the whole of the
4:3 screen.
When the distance from the lens center to the bottom of the image [H] is a negative number, this indicates
that the bottom of the image is below the lens center.
Allow a margin of error in the value in the diagrams above.
