Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen depends on
the lens type and the screen size. Ideally, the projector should be positioned perpendicular to the
screen. This way, the image will appear rectangular instead of keystoned (trapezoidal).
The vertical position of the image can be offset – that is moved above or below the optical axis
(lens center) by adjusting the fully motorized lens mount with the keypad. The amount of vertical
offset available depends directly on the lens installed in the projector and can be slightly limited
if horizontal offset has been applied. Vertical offset can also be expressed as the percent of half
the image height OR the number of pixels of shift from lens center. Refer to Figure 2.1 for some
illustrated examples of vertical offset.
Table 2.1 along with Figure 2.2 show the maximum vertical offset of a lens or alternatively, how
much of your projected image will appear above or below lens center if the maximum vertical
offset is applied using that lens.
Table 2.1 Lens Offsets
NOTE: 1) Offsets are subject to ±7% centering tolerance 2) % Offset = # pixels of offset / half panel resolution x 100.
