Calculation of the projection distance
For a screen size different from the above, use the equation below to calculate the projection distance.
4:3 aspect ratio ET-D75LE6 minimum L (mm) = (diagonal screen size in inches) x 20.7 - 56.6
maximum L (mm) = (diagonal screen size in inches) x 24.8 - 73.6
ET-D75LE1 minimum L (mm) = (diagonal screen size in inches) x 30.68 - 76.0
maximum L (mm) = (diagonal screen size in inches) x 40.98 - 100.4
ET-D75LE2 minimum L (mm) = (diagonal screen size in inches) x 41.15 - 79.5
maximum L (mm) = (diagonal screen size in inches) x 61.73 - 106.4
ET-D75LE3 minimum L (mm) = (diagonal screen size in inches) x 61.73 - 95.8
maximum L (mm) = (diagonal screen size in inches) x 103.09 - 121.6
ET-D75LE4 minimum L (mm) = (diagonal screen size in inches) x 103.09 - 115.8
maximum L (mm) = (diagonal screen size in inches) x 163.93 - 101.3
ET-D75LE8 minimum L (mm) = (diagonal screen size in inches) x 163.95 - 386.2
maximum L (mm) = (diagonal screen size in inches) x 307.18 - 359.8
ET-D75LE5 (fixed focus) L (mm) = (diagonal screen size in inches) x 15.798 - 83.5
• The figures in the above table may vary by approximately ±5% depending on the projection lens that is used.
• When vertical keystone correction is used, the image is corrected in the direction that reduces its projected size.
• At the shortest projection distance, the zoom lens characteristics may cause slight image distortion.
Shift range
Optical axis shift function allows to shift the position of a projected image as shown below.
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 360°.
• Horizontal direction
The projector may be installed at a horizontal
angle of ±15°.
ET-D75LE1/D75LE2/D75LE3/D75LE4/D75LE8 ET-D75LE6
• Because the ETD75LE5 is a fixed short-throw lens, the lens shift function cannot be used with it.
