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.
Choose the installation type that best suits your needs: front or rear screen, floor mount
or inverted mount.

Front Screen Installations
In front screen installations the projector and audience are positioned in front of the
screen, which can be flat or curved.
Flat screens are recommended with this projector. They offer a gain of about 1 with a
viewing angle just less than 180°. This type of screen reflects incident light equally in all
directions so the audience can see the display from various angles.
Curved screens have a gain greater than 1 with a viewing angle much less than 180°.
This type of screen does not reflect incident light equally in all directions; instead, it
is concentrated in a viewing cone. The audience sitting within the viewing cone area
sees a brighter image than those sitting just outside this area. Vidikron generally does
not recommend use of curved screens due to excessive brightness and uncorrectable
geometrical distortion.
