considered minimal, you may prefer to use the projector’s software control to

slightly stretch the image either horizontally or vertically—enough to utilize the

remaining pixels while not noticeably distorting the image.

Displaying Both ‘Flat” and “Scope”

As an example, two standard types of displays common in theatres—flat and

scope—differ in their width-to-height aspect ratio as shown below:

Figure 2.9 Typical Wide Formats

Achieving either of these displays from a variety of incoming source material

(that may or may not be in a format matching that of the screen) depends on

lenses, proper settings in the projector, and certain room conditions.

The extraordinary brilliance of this projector is 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 stray 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.

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, which 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 overall effect. A good rule of thumb is to be no closer than

1.5 times the width of the screen.

Your installation site, the available screen, and ambient lighting all affect where

the projector should be positioned. In addition, both throw distance (the distance

between the projector and screen) and vertical position (the height of the

projector in relation to the screen) must be determined for every new installation.
