3.5 Adjust the Projector Position
When you select a position for the projector, consider the size and shape of your screen, the location of your power outlets, and the distance between the projector and the rest of your equipment. Follow these general guidelines:
• Position the projector on a flat surface at a right angle to the screen. The
projector (with the standard lens) must be at least 3 feet (0.9m) from the projection screen.
• Position the projector to the desired distance from the screen. The distance
from the lens of the projector to the screen, the zoom setting, and the video format determine the size of the projected image.
• For the fixed short lens, the image exits at a default angle. However, the
lens shift feature makes the image offset variable.
• Lens throw ratio:
- Lens 1.22~1.53 (WU/HD)
- Lens 0.95~1.22 (WU/HD)
- Lens 1.52~2.92 (WU/HD)
- Lens 1.28-1.61 (WX)
- Lens 1.0-1.28 (WX)
- Lens 1.6-3.07 (WX)

600 pixels above lens center.

3.6 Calculate Lens Offset
• The vertical image offset (shift) ranges for the projector are +/-100% (WXGA/WUXGA) and +/-120% (HD). The horizontal image offset (shift) range for the projector are +/-30% (WXGA/HD/WUXGA).
• The method for calculating lens offset complies with Industry standards. Example for Vertical lens offset:
- At 0% offset (or on axis), the center of the image is on the lens center,
so that half of the image appears above and half appears below the lens center.
- At +100% offset, all (or 100%) of the image will appear above the lens
center.
- The % offset is calculated as the ratio of the number of pixels shifted up/
down to half the image size. Examples for WUXGA:
Shifting up 600 pixels gives offset of 600/600 * 100% = 100%Shifting down 600 pixels gives offset of -600/600 * 100% = -100%Shifting up 720 pixels gives offset of 720/600 * 100% = 120%Shifting up 240 pixels gives offset of 240/600 * 100% = 40%
