Outside windows are undesirable in any projection room. A small crack between
curtains on a sunny day can wash out a projected image. If you do have
windows, make sure that window coverings are opaque and overlapping — some
window coverings are designed to provide up to 100 percent blockage of outside
light. Ideally, the material should have a matte finish.
To minimize the effects caused by unwanted light from door and aisle ways,
carefully choose the position of your projector and screen. Figure 2.3 shows an
installation where poor screen placement allows too much unwanted light to
enter the screen. In Figure 2.4, the screen and the projector are positioned so that
unwanted light is minimized.

Even with all lighting removed it is still possible that room reflections within the
room can degrade the image. Light from the projection screen should be
absorbed by the ceilings, walls and floors so that it will not be reflected back to
the screen. Again, reflective surfaces should be kept to a minimum.
Here are some other considerations and tips which can help you improve your
installation:
•
Ventilation is an important factor when preparing a projection room. The
ambient temperature should be kept constant and below 35°C (95°F). Keep
the projector away from heating and/or air conditioning vents. Changes in
