For screen sizes between 40” and 500” not indicated on the above table, use formulas below.
Projection Distance = Screen Width (H)ןLens Magnification
Throw distance for GT10RL lens (m/inch) =Hן1.0 (For H between 0.8 m / 31.5 inch and 6.1 m / 240.2 inch)
Throw distance for GT13ZL lens (m/inch) =Hן1.3 through Hן1.6 (For H between 1.1 m / 43.3 inch and 9.8 m / 385.8 inch)
Throw distance for GT19ZL lens (m/inch) =Hן1.8 through Hן2.4 (For H between 1.5 m / 59 inch and 14.6 m / 574.8 inch)
Throw distance for GT34ZL lens (m/inch) =Hן3.4 through Hן5.2 (For H between 5.5 m / 216.5 inch and 52.8 m / 2078.7 inch)
NOTE: Distances may vary +/-5%.
