Alignment and Adjustment
If the image on the screen is not positioned accurately, alignment of the optical engine may be required. It is important to check this mechanical adjustment of the optical engine before any electronic adjustments are made to the picture. Refer to the Aligning the Optical Engine section of the Installation/Operation manual.
If the aspect ratio of the image does not match that of the display, scaling and cropping adjustments can be made to compensate. Refer to the Scaling and Cropping section of the Installation/Operation manual.
