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" diagonal. If these screen sizes are needed, see the information below on removing the metal plate. Information in "blue" shows the screen size range for each lens with the metal plate left on the lens. Information in "red" shows the screen size range for each lens with the metal plate removed.
