Projector positioning
B Distance between ceiling and top of the screen
A Correction value, extra value to be added to B to obtain the correct installation position. (In some cases the A value can be
negative).
CD Total distance between projector and distance.
SW Screen width
PD Perpendicular distance between screen and projector.
CD = A + B. When the result is negative, enlarge the distance between ceiling and top of the screen, mount screen lower, until CD
becomes zero or positive)
3.3 Lens Formulas
Lens Formulas
The lens formulas should be used to calculate the ideal projector distance:
Lens type HD145
PD[meter] = 1.2642 x SW[meter] + 0.2156 A[cm] = 12 x SW[meter] - 22.88
PD[inch] = 1.2642 x SW[inch] + 8.48 A[inch] = 0.12 x SW[inch] - 9
Max phosphor width on CRT = 11cm (4.33 inch).
