GT10RLB and GT20ZL Screen Size Information 
These two lenses are a newer lens designed optimally for newer models in the GT Series. 
They are both fully backward compatible with the GT1150/2150, but to obtain the full screen size range the metal plate at the back 
of the lens may need to be removed. This is only an issue when the GT10RLB is used for screen sizes from 100” – 200” diagonal 
and when the GT20ZL is used for screen sizes from 250” – 300”...
