Lens Option 3: Throw Distance 1.77 - 2.35 x Width of Screen
When only Vertical or only Horizont
al Shift is used:
Maximum. Vertical Shift = 60% of screen height (.6 x height)
Maximum Horizontal Shift = 25% of screen width (.25 x width)
Amount of Horizont
al Shift when Vertical is @ maximum:
Maximum Horizontal Shift = 5% of screen width (.05 x width)
Amount of V
ertical Shift when Horizontal is @ maximum:
Maximum Vertical Shift = 10% of screen height (.10 x height)
Explanation:
• 0% shift is when the image center is even with the projector lens center - also known
as zero-degree projection-angle
• 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
Example: 56" x 100" Screen
TD = 177" to 235" lens to screen
0.60 X 56" = 33.6" up or down
0.25 X 100" = 25.0" left or right
0.05 X 100" = 5.0" left or right
0.10 X 56" = 5.6" up or down
