Hi, I am planning to install my new HD 81.
My screen is 2040 by 115, and I have been able to calculate ideal distance from the screen.
What height above the upper level of the screen should the centre of the lens be if I want to avoid any keystone correction?
The image offset of the unit is 136%. In other words how do you calculate image offset in cm or inches.
Is it as staightforward as 36% of the screen height or is there more to it?
Kind Regards,
George.
