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) x 27.6 - 45
maximum
L (m) = (diagonal screen size in inches) x 37.2 - 48
minimum
L (m) = (diagonal screen size in inches) x 28.0 - 54.0
maximum
L (m) = (diagonal screen size in inches) x 40.3 - 49.8
minimum
L (m) = (diagonal screen size in inches) x 37.1 - 51
maximum
L (m) = (diagonal screen size in inches) x 49.0 - 50
minimum
L (m) = (diagonal screen size in inches) x 50.4 - 66
maximum
L (m) = (diagonal screen size in inches) x 82.4 - 76
minimum
L (m) = (diagonal screen size in inches) x 48.8 - 80.0
maximum
L (m) = (diagonal screen size in inches) x 77.1 - 79.2
minimum
L (m) = (diagonal screen size in inches) x 69.7 - 106
maximum
L (m) = (diagonal screen size in inches) x 91.0 - 106
minimum
L (m) = (diagonal screen size in inches) x 77.0 - 135.1
maximum
L (m) = (diagonal screen size in inches) x 116.3 - 134.6
minimum
L (m) = (diagonal screen size in inches) x 92.6 - 137
maximum
L (m) = (diagonal screen size in inches) x 173.0 - 135
minimum
L (m) = (diagonal screen size in inches) x 116.5 - 301.7
maximum
L (m) = (diagonal screen size in inches) x 184.2 - 299.1
(fixed focus)
L (m) = (diagonal screen size in inches) x 16.6 - 36
(fixed focus)
L (m) = (diagonal screen size in inches) x 17.1 - 47.6

•
Distances calculated with the above equations will include a slight error.
•
When an SXGA signal is input, the left and right edges of the image are blanked, and the image is projected at a screen aspect ratio of 5:4.
•
The brightness varies depending on the zoom setting.
