a’(N) = {(PS × 29.415) × 1.03} - 32.0 + 16.4
a’(M) = {(PS × 35.283) × 0.97} - 32.0 + 16.4

(When “Aspect” on the Signal menu is set to “Full 2”)
a’(N) = {(PS × 31.147) × 1.03} – 32.0 + 16.4
a’(M) = {(PS × 37.367) × 0.97} – 32.0 + 16.4
x = b + {PS × 4.481 + (a’+ 32.0 – 16.4) × 0.07344 – 2.3 + 72.5}
• The projected image size is the one when “Aspect” on the Signal menu is set to “Full 2”. When
“Aspect” on the Signal menu is set to other than “Full 2”, black bands may appear at the top and
bottom or right and left of the screen.
• When “Aspect” in the Signal menu is set to “4:3”, the projected image size (diagonal) will be
approximately 88% of “Full 2” size.
• When “Aspect” in the Signal menu is set to “16:9”, the projected image size (diagonal) will be
approximately 97% of “Full 2” size.
The alphabetical letters in the charts and calculation methods indicate the following.
PS: projected image size measured diagonally
a’: distance between the hole (front) for mounting a projector suspension support on bottom
surface of this projector and the center of the screen
b: distance between the projector suspension support mounting surface on bottom of this
projector and the ceiling
x: distance between the center of the screen and the ceiling
