Projection schemes
Any of the following four projection schemes can be
used with the PT-D5500U/D5500UL projector
depending on user’s needs or viewing conditions.
Use “OPTION 2” menu (chosen from the MAIN
MENU) to choose the appropriate projection
scheme (see page 34).
Projection Scheme 1
Front projection
Rear projection
Table standing
Projection Scheme 2
Ceiling mount
(Default position)
Installation geometry
After the projector is roughly positioned, picture size
and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens tilt
mechanism.

Setting-up dimensions which are not given in the
above table can be calculated using the formulas
below.
LW = 0.0370 x SD – 0.0650
LT = 0.0488 x SD – 0.0638
(LW,LT: m SD: inch)
For 16 : 9 aspect rations, the following formal can be
used to calculate the screen width (SW).
SW = (SD x 0.0254) x 16 ÷ 337
The value for SW obtained above can then be used
with the following function to calculate the projection
distance for the wide lens position (LW) and the
projection distance for the telephoto lens position (LT).
LW = 1.823 x SW – 0.0650
LT = 2.403 x SW – 0.0638
Note
• The dimensions in the table above and
the values obtained from the above
formulas may contain slight errors.
• It is recommended that you use the
projection distance for the wide lens
position.
• The above dimensions are the case
when the aspect ratio is 4:3. When an
SXGA signal is input and projected,
the right and left ends of the picture
will be blanked the aspect ratio will be
5:4.
Projection distances
Listed in the table below are the projection
distances of the standard lens provided with the
PT-D5500U (with lens).
Refer to page 57 for the projection distances of the
projection lenses available as optional accessories.
