ADDITIONAL INFORMATION
Projection distance
The distance between the projector and its screen determines the approximate size of the image. The farther the
projector is from the screen, the larger the projected image will be. The image size also varies depending on the
aspect ratio, zoom and other settings.
Powered lens shift range
Projection Lens
BX-CTA15
V: Height of the projected image
H: Width of the projected image
Projected image
When the lens is shifted beyond the described range of operation,
screen edges may become darker or images may become out of
focus.
Note:
The calculation is based on 1/2 image width and 1/2 image height.
