WARP
Correct projected image distortion on a specific surface as a column or a sphere.
NOTE:
• When the maximum adjustment range is exceeded, distortion adjustment is disabled. Set up the projector at an optimal angle
since the more the adjustment volume gets large, the more image quality gets deterioration.
• Please note that the image will go out of focus due to the difference in the distance between peripheries and the center of the screen
for projections cutting across corners as on a column or a sphere. Lenses with short focal points are also not recommended for
projections cutting across corners as the image will go out of focus.
