Installation Considerations
Proper installation of your projector will ensure the quality of your display. Whether you are
installing a projector temporarily or permanently, you should take the following into account
to ensure your projector performs optimally.
Installation Type Choose the installation type that best suits your needs: front or rear screen, floor mount or
inverted mount.
Table 3-2 compares these various installation methods.
Ambient Light In general, minimize or eliminate light sources directed at the screen. Contrast ratio in your
images will be noticeably reduced 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.
