When the Screen Size is not Mentioned in the Tables
You can calculate the installation measurements described below when you
use the screen whose size is not mentioned in the tables on pages 9 (GB),
10 (GB) and 12 (GB), 13 (GB).
Check your installation conditions:
• Screen size to be used (S)
• Installation measurements at the end of the manual, EL and BL for larger
screen size and ES and BS for smaller screen size
See the tables on pages 105 (GB) to 113 (GB).
Now you can calculate the installation measurements as follows:
E (mm) = ES + ((S – smaller screen size) × (EL – ES) × 0.1)
B (mm) = BS + ((S – smaller screen size) × (BL – BS) × 0.1) + 254
Example: when using 124-inch screen
According to the tables on pages 106 (GB) and 107 (GB), the values E and
B are as follows:
ES = 3571, BS = 860 (As the smaller screen size is 120 inch.)
EL = 3856, BL = 929 (As the smaller screen size is 130 inch.)
Therefore,
E (mm) = 3571 + ((124 –120) × (3856 – 3571) × 0.1) = 3685 (mm)
B (mm) = 860 + ((124 – 120) × (929 – 860) × 0.1) + 254 = 1142 (mm)
