Formulas: 16:10 Aspect Ratio (PE455WL - WXGA)
The Projection Formulas use the image width for calculation. Image width is the same for all aspect ratios, only vertical image size
varies. For proper projector placement, determine the image width for a desired screen size. Use the Screen Formulas below to
calculate all screen dimensions. Plug in the image width for “W” in the Projection Formulas.
Refer to the diagrams and charts for popular screen sizes on page 4:
16:10 Screen Formulas:
W = H x 16/10
H = W x 10/16
Screen Diagonal = W x 18.868/16
Projection Formulas:
C (wide) = 1.267W – 1.547
C (tele) = 2.103W – 1.539
Vertical Lens Shift Max (Up) = 0.03125W
Vertical Lens Shift Max (Down) = -0.3125W
α (wide) = tanˉ¹ (B/C(wide))
α (tele) = tanˉ¹ (B/C(tele))
Horizontal Lens Shift Max (Right) = 0.26W
Horizontal Lens Shift Max (Left) = 0.-26W
For screen sizes not indicated on the projection tables, use the formulas on page 1.
Note:
Distance Charts
The following shows the proper relative positions of the projector and screen. Refer to the table to determine the position of installation.
Distances are in inches. For millimeters multiply by 25.4.
