Pincushion / Barrel
Pincushion or barrel distortions are the result of poor or incorrect tensioning of the screen
or using a surface that is not flat.
Use the Pincushion / Barrel control to compensate electronically for such distortions.
You can also use this menu to make simple panoramic screen corrections without using
external processors.
When also correcting for keystone, the aspect ratio of the projected image may be incorrect.
This is dependent upon the throw ratio of the lens at its current zoom setting. Adjust the
lens throw ratio to compensate for the aspect ratio that results from the zoom setting on
the lens.
Pincushion/ Barrel example
The illustration shows pincushion
and barrel correction applied
both horizontally and vertically,
in equal measures.
