Lens Option 3: Throw Distance 1.77 - 2.35 x Width of Screen

When only Vertical or only Horizontal 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 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)

•    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

Amount of Vertical Shift when Horizontal is @ maximum:
Maximum Vertical Shift = 10% of screen height (.10 x height)

•    0% shift is when the image center is even with the projector lens center - also known
