Section 2: Installation and Setup
The vertical position of the image can be offset (that is moved above or below the optical axis) by adjusting the
motorized lens mount. The amount of vertical offset available depends on the type of lens installed in the
projector and can be limited if horizontal offset has been applied. Vertical offset can be expressed as the
percent of half the image height or the number of pixels of shift from lens center. See Figure 2-1 Vertical
Offset Examples for illustrated examples of vertical offset.
Table 2.1, Table 2.2 and Table 2.3 specify the vertical offset of each type of lens.
