Calculating the lens offset
Adjust the offset to align the image on the screen with half image size.
• The vertical image offset (shift) ranges for the projector are +/-100% (WUXGA) and
+/-120% (HD).
• The horizontal image offset (shift) range for the projector is +/-30% (HD/WUXGA).
• The method for calculating lens offset complies with industry standards. 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, the entire of the image appears above the lens center.
• The percentage (%) offset is calculated as the ratio of the number of pixels shifted up or
down to half image size.
WUXGA projectors
The following show vertical image offsets for the WUXGA projectors:
• Vertical image offset: 0%
