1. Screen type: installed permanently or portable ?
The choice between a portable projection screen and the wall- or ceiling mounted one depends on the circumstances and the personal preferences and needs of its users. In general however, if only possible, a wall- or ceiling mounted, fixed or manually or electrically retractable screen will be preferred over a portable one. The latter can be a handy solution to those who need to use a projector in a variety of places.
Tripod screens are convenient and compact and can easily be transported between rooms within the same building. Folded screens are also designed with portability in mind, yet they can provide more space than their tripod counterparts.
Wall-mounted screens can be lowered and retracted manually or electrically and are installed permanently. Manual projection screens must be manually prepared (lowered) for use. Electric projection screens are lowered and retracted by an electric motor, which can be operated using a remote control or a wall switch. They are perfect particularly for conference rooms equipped with compatible equipment control systems.
