This is a general example of lens shift. Lenses vary in their shift capabilities. No particular lens or projector is used in this example.
Figure 3-6: Horizontal Lens Shift (Example Only)
1.With no vertical or horizontal lens shift, the lens center and screen center are aligned with each other.
2.Vertical shift limits are percentages of the screen height. Horizontal shift limits are percent- ages of the screen width.
3.Vertical lens shift figures are for ceiling mount configurations. For floor installations (where the projector is upright), reverse the up/down vertical lens shift percentages.
