“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.

You must enter a passcode to access the Calibration menu.

Note

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 3-22.

Use the built-in test pattern when adjusting the image corners or

Tip midpoints. To access it, check the Test Pattern box in the Corner

Alignment or Midpoint Alignment menu.
