Figure 2.12. Vertical Offset Range
NOTE:
1)
Assumes full 2048 x 1080 display.
2)
Recommended offset range can
sometimes be exceeded, however this may affect image quality.
3)
Due to
manufacturing tolerances, an offset range can vary ±5% or
more between lenses
described as having the same throw ratio, between projectors, and with any
lens/projector combination.
4)
Simultaneous horizontal and vertical offset can limit
the adjustment range of each, as can long throw distances.
ALTERNATIVE METHOD OF DESCRIBING VERTICAL OFFSET:
Offset can also be
specified as the
distance traveled
from lens center (such as 270 pixels) and expressed
as a percentage (270 pixels=50%) of
half of the image height
. This concept of image
movement is illustrated in the example below:
