“Keystoning” usually occurs when the projector is tilted relative to the screen. “Pincushion”
distortion can sometimes occur if the throw distance is very short and/or the projector is
equipped with an anamorphic lens.
To correct keystoning or pincushion distortion:
1.
On the DHD Controller remote control or front panel, press MENU.
2.
Select Calibration from the Main Menu and enter the Calibration Menu passcode.
3.
Select Image Alignment from the Calibration Menu.
4.
Select Corner Alignment to correct a “keystoned” image by adjusting the image
corner positions. Select Midpoint Alignment to correct pincushion distortion by
adjusting the image edge mid-points. See Figure 3-18.
