2.2.4 Ambient Lighting
The extraordinary brilliance of this projector is certainly well suited for locations where ambient lighting might
be considered less than ideal for projection. Even a typical room or large auditorium fully lit with ceiling lights
and windows rarely requires special attention. Contrast ratio in your images will be noticeably reduced only 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.
In general, avoid or eliminate light sources directed at the screen.
2.2.5 Other Considerations
Other considerations and tips that can help improve your installation:
• Keep the ambient temperature constant and below 35°C (95°F). Keep the projector away from heating and/
or air conditioning vents. Changes in temperature may cause drifts in the projector circuitry that may affect
performance.
• Keep the projector away from devices that radiate electromagnetic energy such as motors and transformers.
Common sources of these include slide projectors, speakers, power amplifiers, elevators, etc.
• Choose the best screen size for the application. Since more magnification reduces brightness, use a screen
size appropriate for the venue, but not larger than required. Installing a large screen in a small room is similar
to watching television at a close range; too large a screen can overpower a room and interfere with the over-
all effect. A good rule of thumb is to be no closer than 1.5 times the width of the screen.
