Installation Considerations
Proper installation of your projector will ensure the quality of your display. Whether you are
installing a projector 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 Figure 3-2. The result
of this calculation tells you roughly how far back the projector should be positioned from
the screen in order to project a focused image large enough to fill the screen.
Throw Distance (TD) = Screen Width (W) x Throw Ratio (TR)

Note:
H9090 is available with multiple lens options. The standard H9090 offers throw ratios
between 1.85:1 - 2.40:1. With the optional, short-throw lens with throw ratios between
1.56:1 - 1.86:1, and long-throw lens with throw ratios between 2.40:1 – 4.0:1.
