Rear screen installations
There are two basic types of rear screens: diffused and optical.
A diffusion screen has a surface which spreads the light striking it. Purely diffused screens 
have a gain of less than 1. The main advantage of the diffused screen is its wide viewing 
angle,  similar  to  that  of  a  flat  screen  for  front  screen  projection.  This  type  of  screen  is 
suitable when a wide viewing...

The  high  brightness  of  this  projector  is  well  suited  for  locations  where  ambient  lighting 
might be considered less than ideal for projection. A typical room with ceiling lights and 
windows rarely requires special attention. 
Contrast ratio in your images will be noticeably 
reduced  only  if  light  directly  strikes  the  screen,  such  as  when  a  shaft  of  light  from  a 
window  or  floodlight...

Vertical and horizontal position
The correct vertical and horizontal position of the projector in relation to the screen 
depends on the lens type and the screen size. Ideally, the projector should be positioned 
perpendicular to the screen. This way, the image will appear rectangular instead of 
keystoned (trapezoidal).
The 
vertical position  of the image can be offset – that is, moved above or below 
the optical...

Table  2.1,  Table  2.2  and  Figure  2.3  show  the  maximum  vertical  offset  of  a  lens  or 
alternatively, how much of your projected image will appear above or below lens center if 
the maximum vertical offset is applied using that lens.

The 
horizontal position of the image can be offset – that is, moved to the left or right of 
lens center – by adjusting the fully motorized lens mount. The amount of horizontal offset 
available depends on the lens installed and if the image has already been vertically offset. 
Horizontal  offset  can  also  be  expressed  as  the  percent  of  half  the  image  width  –  the 
number  of  pixels  of  shift  to  one...
