Image and Screen Size Calculations Use the calculations to determine the distance from the screen and size of the image. Standard Zoom Lens (V12H004S02) To find the distance when you know the screen's diagonal size: ■ Distance at Wide setting (inches) = (diagonal screen size [inches] × 3.7857 - 9.6813)/2.54 ■ Distance at Tele setting (inches) = (diagonal screen size [inches] × 5.175 - 9.5418)/2.54 To find a screen's diagonal size when you know the distance: ■ Screen size at Wide setting (inches) = (projection distance [inches] × 0.264152 × 2.54) + 2.557334 ■ Screen size at Tele setting (inches) = (projection distance [inches] × 0.193237 × 2.54) + 1.843826 Rear Projection Wide Lens (V12H004R02) To find the distance when you know the screen's diagonal size: Distance (inches) = (diagonal screen size [inches] × 1.81553 - 6.59805)/2.54 To find a screen's diagonal size when you know the distance: Screen size (inches) = projection distance [inches] × 2.54 × 0.5508024 + 3.634232 Wide Zoom Lens (V12H004W02) To find the distance when you know the screen's diagonal size: ■ Distance at Wide setting (inches) = (diagonal screen size [inches] × 2.68681 - 6.80456)/2.54 ■ Distance at Tele setting (inches) = (diagonal screen size [inches] × 3.80739 - 6.46563)/2.54 To find a screen's diagonal size when you know the distance: ■ Screen size at Wide setting (inches) = (projection distance [inches] × 2.54 × 0.372189 + 2.53258) ■ Screen size at Tele setting (inches) = (projection distance [inches] × 2.54 × 0.262647 + 1.698179) 18 Setting Up the Projector

Image and Screen Size Calculations
Use the calculations to determine the distance from the screen and size
of the image.
Standard Zoom Lens (V12H004S02)
To find the distance when you know the screen’s diagonal size:
■
Distance at Wide setting (inches) =
(diagonal screen size [inches]
×
3.7857 - 9.6813)/2.54
■
Distance at Tele setting (inches) =
(diagonal screen size [inches]
×
5.175 - 9.5418)/2.54
To find a screen’s diagonal size when you know the distance:
■
Screen size at Wide setting (inches) =
(projection distance [inches]
×
0.264152
×
2.54) + 2.557334
■
Screen size at Tele setting (inches) =
(projection distance [inches]
×
0.193237
×
2.54) + 1.843826
Rear Projection Wide Lens (V12H004R02)
To find the distance when you know the screen’s diagonal size:
Distance (inches) =
(diagonal screen size [inches]
×
1.81553 - 6.59805)/2.54
To find a screen’s diagonal size when you know the distance:
Screen size (inches) =
projection distance [inches]

0.5508024 + 3.634232
Wide Zoom Lens (V12H004W02)
To find the distance when you know the screen’s diagonal size:
■
Distance at Wide setting (inches) =
(diagonal screen size [inches]
×
2.68681 - 6.80456)/2.54
■
Distance at Tele setting (inches) =
(diagonal screen size [inches]
×
3.80739 - 6.46563)/2.54
To find a screen’s diagonal size when you know the distance:
■
Screen size at Wide setting (inches) =
(projection distance [inches]
