Installation Considerations
Proper installation of your projector will ensure the quality of your display. Whether you are installing a projec-
tor temporarily or permanently, you should take the following into account to ensure your projector performs
optimally.
Ambient Light
In general, minimize or eliminate light sources directed at the screen. Contrast ratio in your images will be noticeably
reduced if light directly strikes the screen, such as when a shaft of light from a window or floodlight falls on the image.
Images may then appear washed out and less vibrant.
Requires separate room Installation cost is usually higher.
Throw Distance
Throw distance is the distance measured from the front of the projector to the screen. This is an important calculation in
any projector installation as it determines whether or not you have enough room to install your projector with a de-sired
screen size and if your image will be the right size for your screen. You can quickly estimate the throw distance by taking
the width of the screen and multiplying it by the lens throw ratio; see the image as following. The result of this calcula-
tion tells you roughly how far back the projector should be positioned from the screen in order to project a focused im-
age large enough to fill the screen.

Throw Distance (TD) = Screen Width (W) x Throw Ratio (TR)

Two models of the D8800/D8900/D8010W are available, one with 1.56-1.86:1 lens and the other with 1.85-2.40:1 lens
With optional zoom adaptors throw ratios of 1.24 – 3.0 can be achieved. The standard D8800/D8900/D8010W offer
throw ratios between 1.85:1 and 2.40:1. With the optional, short-throw lens, the D8800/D8900/D8010W offer throw
ratios between 1.56:1 and 1.86:1.
