Projection scheme
This projector can use any of the four projection schemes. Select the most suitable scheme to the situation of
your location. Use the INSTALLATION menu to choose the desired projection scheme. (p. 78)
Installation geometry
When planning the projector and screen geometry, refer to the figures below and the information on the next page
for reference. After the projector is roughly positioned, picture size and vertical picture positioning can be finely
adjusted with the powered zoom lens and lens shifting mechanism.

* For PT-D12000E:
H = 0 to SH
For PT-DZ12000E:
H = -0.1 × SH to 1.1 × SH
* However, if the ET-D75LE5 has been installed,
the value will be fixed at H=SH/2 for both the
PT-D12000E and PT-DZ12000E. If the ET-D75LE6
has been installed, the values will be H = 0.1 × SH
to 0.9 × SH for the PT-D12000E, and H = 0 to SH
for the PT-DZ12000E.
