Take into account that wh en the projector is tilted the Screen Width you have t o fill in should be larger than
the physical screen width due to the keystone distortion of the projected image. How m uch larger depends
ontheamountoftilt.
Due to production tolerances the real distances can differ by 2% from the calculated values.
For critical situations ( fixed installs that use the lens at one of its extreme zoom positions) this should be
taken into account.
