Calculating The Lens Offset - Christie HS Series Installation And Setup Manual

Calculating the lens offset

Adjust the offset to align the image on the screen with half image size.
• The vertical image offset (shift) range for the projector is up to +/-120% (WUXGA) and
+/-140% (HD).
• The horizontal image offset (shift) range for the projector is up to +/-50% (HD/WUXGA).
• The method for calculating lens offset complies with industry standards, with which the image
offset is calculated by half image size. For example for Vertical lens offset:
• At 0% offset (or on axis), the center of the image is on the lens center, so half of the
image appears above and half appears below the lens center.
• At +100% offset, all of the image appears above the lens center.
The following show the vertical and horizontal image offsets for the HS Series D16-20 projectors:
• Vertical image offset: 0%
• WUXGA Vertical image offset: +/-120%
