Installation guidelines
Careful consideration of things such 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 the 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. This 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.
