Operation

Pincushion: “Pincushion” distortion can sometimes occur if the throw distance is very short and/or the projector is equipped with an anamorphic lens (refer to Installing and Adjusting the CineWide Anamorphic Lens in Section 3). To correct it, select Pincushion from the GeoCorrection menu and use the or button to make the image rectangular. See Figure 4-7.
