Installation Guidelines
Careful consideration of things as image size, ambient light level, projector placement and type of screen to use are critical to the optimum
use of the projection system.
* Environment
Do not install the projection system in a site near heat sources such
as radiators or air ducts, or in a place subject to direct sunlight,
excessive dust or humidity. Be aware that room heat rises to the
ceiling; check that temperature near the installation site is not
excessive.
* What about Ambient Light ?
The ambient light level of any room is made up of direct or indirect
sunlight and the light fixtures in the room. The amount of ambient light
will determine how bright the image will appear. So, avoid direct light
on the screen.
Windows that face the screen should be covered by opaque drapery
while the set is being viewed. It is desirable to install the projecting
system in a room whose walls and floor are of non-reflecting material.
The use of recessed ceiling lights and a method of dimming those
lights to an acceptable level is also important. Too much ambient light
results in a wash out of the projected image. That appears as less
contrast between the darkest and lightest parts of the image. With
bigger screens, the wash out becomes more important. As a general
rule, darken the room to the point where there is just sufficient light
to read or write comfortably. Spot lighting is desirable for illuminating
small areas so that interference with the screen is minimal.
