Image Alignment Controls - Runco Q-750d Ultra Series Installation & Operation Manual

Installation
"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 3-23.
