Arc
This feature is similar to Pincushion / Barrel but allows you to apply curvature to each 
edge of the image independently so you can have any combination of corrections.

Notes
  Please note that a positive Arc 
value on any edge will reduce the 
image size as the projector needs to 
maintain the aspect ratio.
  A negative 
Arc value will not affect 
the overall image size.
