Lens Option 5: Throw Distance 3.60 - 5.70 x Width of Screen
When only Vertical or only Horizontal Shift is used:
Maximum. Vertical Shift = 85% of screen height (.85 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)
Explanation:
Example: 56" x 100" Screen TD = 360" to 570" lens to screen
0.85X 56" = 47.6" 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% 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 7% 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 6: Throw Distance 0.67 Fixed x Width of Screen
When only Vertical or only Horizontal Shift is used:
Maximum. Vertical Shift = 15% of screen height (.15 x height)
Maximum Horizontal Shift = 10% of screen width (.1 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)
Explanation:
Example: 56" x 100" Screen TD = 8" lens to screen
0.15X 56" = 8.4" up or down
0.1X 100" = 10.0" left or right
0.05X 100" = 5.0" left or right
0.10X 56" = 5.6" up or down
