There are an even greater number of choices when it comes to a fixed, permanent screen installation. From simple pull down wall or ceiling mounted screens (still very popular in classrooms) to professionally installed recessed electrics with remote control that "disappear" into the ceiling.
In addition there are fixed screens that are permanently mounted directly to the wall with the screen fabric residing within a metal frame, offering a consistently flat surface that is very popular with home theater users. Finally there is the option of painting a screen directly on a wall with a product such as GOO Systems.
