Keystone distortion correction
When attaching this lens for use, regardless of the projector model, set up the projector so that the projected
image is rectangular and the back of the projector and the screen are parallel.
In addition, depending on the projector used, keystone distortion correction may be feasible after setup.

When using one of PT-RZ31K / PT-RS30K / PT-RQ13K / PT-RZ12K / PT-RS11K / PT-DZ21K2 /
PT-DS20K2 / PT-DW17K2 / PT-DZ16K2 / PT-DZ13K / PT-DS12K / PT-DZ10K
For keystone distortion in the vertical direction generated within the angle range below, select [MAIN MENU]
→
[POSITION] → [GEOMETRY] → [KEYSTONE] → [VERTICAL KEYSTONE] to perform correction.
Keystone distortion in the vertical direction greater than this angle and keystone distortion in the horizontal
direction can be corrected but the projected image overall will no longer be in focus.
Correction feasible angle (α): 0 - 5°
z
When using PT-DW11K
If keystone distortion in vertical direction or horizontal direction is corrected, the projected image overall will no
longer be in focus. Set up the projector so that the projected image is rectangular and the back of the projector
and the screen are parallel.
z
When using a projector other than one listed above
Please see "Setting up" in the operating instructions for the projector you are using.
