Installing the Projector (Cont.)
Lens Shift Function (Cont.)
Maximum amount of shift
The maximum amount of vertical shift is restricted by the amount
of horizontal shift made.
The amount of shift is defined as follows:
With the screen width taken as 1, horizontal shift is defined as a
ratio (%) of the screen width, while with the screen height taken
as 1, vertical shift is defined as a ratio (%) of the screen height.
