When using the 16:9 aspect ratio screen
Unit: mm (inches)
To calculate the installation measurements (SS: Screen Size)
a (minimum) ={(SS × 33.56/0.8788) – 56.520408} × 1.025
a (maximum) ={(SS × 42.359182/0.8788) – 57.18141} × 0.975
x = b + (SS/0.8788 × 5.516)
When using the 4:3 aspect ratio screen
Unit: mm (inches)
To calculate the installation measurements (SS: Screen Size)
a (minimum) ={(SS × 33.56/0.7240) – 58.520408} × 1.025
a (maximum) ={(SS × 41.3591819/0.7240) – 57.181415} × 0.975
x = b + (SS/0.7240 × 5.516)
