Lens Shift Range
The examples show the location of the image position in the lens. The lens can be shifted within the shaded area as shown using the normal projection position as a starting point. Note: If lens is shifted in two directions combined, max. range in either direction cannot be obtained due to rounded off area near edge of lens. (Example: shift up and left). See diagrams below:
Lens Option 1: Throw Distance 1.57 - 1.95 x Width of Screen
When only Vertical or only Horizontal Shift is used:
Maximum. Vertical Shift = 90% of screen height (.9 x height)
Maximum Horizontal Shift = 40% of screen width (.4 x width)
Amount of Horizontal Shift when Vertical is @ maximum:
Maximum Horizontal Shift = 5% of screen width (.05 x width)
Amount of Vertical Shift when Horizontal is @ maximum:
Maximum Vertical Shift = 10% of screen height (.10 x height)
The maximum shift in 2 directions (ex. maximum left and maximum down): Maximum Vertical Shift w/ Horizontal = 40% of screen height (.4 x height) Maximum Horizontal Shift w/Vertical = 20% of screen width (.2 x width)
Example: 56" x 100" Screen TD = 157" to 195" lens to screen
0.90X 56" = 50.4" up or down
0.40X 100" = 40.0" left or right
0.05X 100" = 5.0" left or right
0.10X 56" = 5.6" up or down
0.40X 56" = 22.4" up or down
0.20X 100" = 20.0" left or right
Explanation:
•0% shift is when the image center is even with the projector lens center - also known as
•Shifting beyond the maximum values above will cause image loss in corners or edges
•When Vertical Shift is maximum, Horizontal shift can only be adjusted 5% left or right in example above
•The maximum diagonal movement of the image is expressed as shift in 2 directions, this is the maximum combination of
adjustment (ex. Up & Left, Down & Right, Up & Right, Down & Left)
•Throw distance does not affect image quality
•Lens shift does not affect image quality if within above limits

Lens Option 2: Throw Distance 1.95 - 2.74 x Width of Screen
When only Vertical or only Horizontal Shift is used:
Maximum Vertical Shift = 104% of screen height (1.04 x height) Maximum Horizontal Shift = 48% of screen width (.48 x width)
Amount of Horizontal Shift when Vertical is @ maximum:
Maximum Horizontal Shift = 6% of screen width (.06 x width)
Amount of Vertical Shift when Horizontal is @ maximum:
Max. Vertical Shift = 12% of screen height (.12 x height)
The maximum shift in 2 directions (ex. maximum left and maximum down): Maximum Vertical Shift w/ Horizontal = 51% of screen height (.51 x height) Maximum Horizontal Shift w/Vertical = 29% of screen width (.29 x width)
Example: 56" x 100" Screen TD = 195" to 274" lens to screen
1.04X 56" = 58.2" up or down
0.48X 100" = 48.0" left or right
0.06X 100" = 6.0" left or right
0.12X 56" = 6.7" up or down
0.51X 56" = 28.6" up or down
0.29X 100" = 29.0" left or right
