PROJECTION SCREENS

How to choose the proper type of screen
Which screen is to be preferred first of all depends on the application. For frequent shows in the same location a wall or ceiling screen - manually or electrically operated, with or without frame - should be considered. For shows in different locations a tripod screen resp. a portabe screen is the better solution.
electrical – installed
