Figure 3-4. Horizontal Lens Shift (Example only)
Vertical Lens Shift: The SC-1 provides up to 43% of vertical lens shift up or down. For
example, with a 96 x 54-inch (16:9) screen, you can shift the image up to 23.22 inches
(59.0
cm) above or below the screen center.
Horizontal Lens Shift: The SC-1 allows up to 20% of horizontal lens shift left or right
(17% with a 1.90:1 screen). For example, with a 96
x 54-inch (16:9) screen, you can shift
the image up to 19.20 inches (48.8 cm) left or right of the screen center. With a
95
x 50-inch (1.90:1) screen, you can shift the image up to 16.15 inches (41.0 cm) left or
right of the screen center.
1. With zero offset (no vertical or horizontal lens shift), the lens
center and screen center are aligned with each other. The SC-1
is never ceiling mounted; offsets are calculated only with the
projector upright. These offsets are references to zero offset.
2. Vertical shift limits are percentages of the screen height.
Horizontal shift limits are percentages of the screen width.
3. The SC-1 has a native resolution of 2048 x 1080, which is about
a 1.9:1 aspect ratio. For 16:9 material, only the 1920 x 1080 area
is used which is a 16:9 (1.78:1) aspect ratio. Most often, the 16:9
throw distance is used. If used with CineWide or CineWide with
AutoScope, only the 16:9 area is used.

Note: This is a general example of lens shift. Projectors vary in their shift capabilities. No
particular lens or projector is shown in this example.
