The alphabetical characters in this section indicate the following measurements:
W: Screen width (unit: mm)
D: Screen diagonal length (unit: inch)
L(min): Minimum distance between the center of lens and screen
L(max): Maximum distance between the center of lens and screen
H: Screen height (different from the aspect ratio of the projected image)
The distance between the lens and the screen varies depending on the attached lens, type of the input signal or size of the
projected image. Choose the most suitable distance (L) depending on the screen size (W or D).
The formula for calculating the projection distance from the screen width (W, unit: mm) is as follows:
