f
When [SCREEN ADJUSTMENT] is used, the focus of the entire screen may be lost as correction increases.
f
Make the curved screen a circular arc shape with one part of a perfect circle removed.
Projection distance
A ± 5% error in listed projection distances may occur.
In addition, when [SCREEN ADJUSTMENT] is used, distance is corrected to become smaller than the specified
screen size.
