Even with all lighting removed it is still possible that room reflections within the
room can slightly 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, keep reflective surfaces 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
temperature can cause drifts in the projector circuitry which may affect
performance.
•
Keep the projector away from devices which radiate electromagnetic energy
such as motors and transformers. Common sources of these are slide
projectors, speakers, power amplifiers, elevators, etc.
•
For rear screen applications, less space is required if a mirror is used to fold
the optical path.
•
Choose the right screen size for the application:
