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)
•  360 degree operation (alone the widest axis)

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 rati o 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%
WUXGA Projectors: Vertical Image Offset: 0% Offset (WUXGA)
No offset is applied - 0% offset.
