ENGLISH-9
Projected range using "GEOMETRY(2D)" (PT-DZ870 only)
In a standard configuration and when an optional upgrade kit (part number: ET-UK20) is used, vertical keystone
can be corrected within a range of 0 to 5°.
Horizontal keystone correction cannot be made.

Projected image size and projection distance
Note
z
The listed projection distances involve an error of ±5%.
z
"GEOMETRY(2D)" and "VERTICAL KEYSTONE" tend to correct the projected image to a size that is smaller than
regular size.
z
Throw ratio is based on the value during projection onto a 2.54 m (100") screen.

For PT-DZ870
Units: m (")
