Vertical Lens Shift (Standard Q-750d): The Q-750d provides up to 60% of vertical
lens shift up or down. For example, with a 100 x 56 inch (1.78:1) screen, you can shift
the image up to 33.60 inches (0.85 meters) above or below the screen center.
Vertical Lens Shift (Q-750d/CineWide or Q-750d/CineWide with AutoScope): The
Q-750d provides up to 25% of upward vertical lens shift and up to 60% of
downward vertical lens shift. For example, with a 100 x 56 inch (1.78:1) screen, you
can shift the image up to 14.00 inches (0.36 meters) above or 33.60 inches (0.85 meters)
below the screen center.
Horizontal Lens Shift: The Q-750d provides up to 12.5% of horizontal lens shift
left or right. For example, with a 100 x 56 inch (1.78:1) screen, you can shift the image
up to 12.50 inches (0.32 meters) left or right of the screen center.
Vertical lens shift figures are for ceiling mount
configurations. For floor installations (where the projector is
upright), reverse the up/down vertical lens shift percentages.
