The fixed projector screen is becoming increasingly more popular to use in home theaters, as it is generally much cheaper than buying a large LCD television, and it can be mounted directly on the wall. However, in order to use fixed projector screens in home theaters, you also need to purchase a projector which can sometimes end up pushing the overall costs up to a similar price as buying a television, unless you choose a good quality cheap projector.
Normally, the fixed projector screen is used in situations where it can be left in place, as it is mounted on the wall. Most classrooms these days have retractable electric projector screens, oftentimes mounted directly above the blackboard. That way, when the children want to watch something on the screen, all that the teacher has to do is pull the screen down, and then let it roll back up again when it is finished. Obviously a fixed projector screen is not really an option in a situation such as this.
Businesses sometimes use a fixed projector screen for their business or advertising presentations. These are often installed on the wall of meeting rooms, and are usually positioned at the front of the room so that everyone gathered around the desks can see them. They work very well, providing the room does not have a lot of windows. Unfortunately, many offices, meeting rooms and conference rooms are lined with windows. To enable everyone to see the images on the screen properly it is important that the windows have blackout blinds on them, otherwise the image will be filtered, dim and it will not have the proper depth but will look two dimensional.
Overall, it seems that the most popular location for the fixed projector screen remains the home theater. If you are thinking about attaching a screen to the wall, to use in your home theater there are a few things that you may need to take into consideration. One is that the fixed screen is always in view. Some people prefer to have a retractable screen so that they can decide when their room will turn into a home theater and when it will be a normal family or living room. Another con to the fixed screen is that it is very easy for it to become dusty, or to get other marks on it because it is in plain view all day. It is also possible that the projector screen material may become damaged. If these issues are not a problem for you, and you do not think any harm will come to your screen, then it should be fine to have it attached to the wall in this way.
Fixed projector screens do not work as well in rooms that are painted white, or a light color. This may be an issue in your home, depending on the overall décor of your living quarters, as many people do not like to paint or cover their walls with a darker color. One workaround, rather than painting the walls a dull grey, for example, is to install your fixed projector screen in a room that has darker wood paneling around the walls. This way the room remains aesthetic, and yet it is dark enough not to reflect light or the image.
