Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
Aspect ratio 4:3
minimum L (m) = (diagonal screen size in inches) × 0.03962
maximum L (m) = (diagonal screen size in inches) × 0.04369

Projection distance for 4:3 aspect ratio screen
unit: meters (feet)
NOTE:
• The value for L (distance to screen) varies slightly depending on the zoom lens characteristics.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
Installable angle
Install the projector at an angle within the range shown below.
• Vertical direction
The projector may be installed at a vertical
angle of 10°.
• Horizontal direction
The projector may be installed at a horizontal
angle of 20°.
NOTE:
Distances calculated with the above equations will include a slight error.
