Tripod projection screens are best used when a person needs to be able to
travel with their projection screen.  This type of screen is often referred to as a portable projection screen because it is made to be moved and carried around.  They are most often less than 20 pounds.  Tripod projection screens consist of a base and screen that are both compact.

When choosing a tripod projection screen a person may want to consider the ease of use.  If they travel often and give presentations at a variety of locations they should consider the best sized tripod projection screen.  The screen should be large enough for everyone in the room to see easily.  This means that smaller screens may not be suitable if a person gives presentations to large audiences, however, if a person gives presentations to small groups then a small screen would work great.

Another consideration is the set up and tear down.  Most tripod projection screens are made to be very easy to set up and tear down, however, a person should make sure they can setup and tear down the tripod with ease.  They may not always have someone to help, so it is very important that they can do it by themselves.

Some tripod projection screens come with one type of screen and others come with changeable screen types this is another consideration.  A person who always give presentations in similar environments will be fine with a single type of screen, but a person who gives presentations at various locations should look fro changeable screens so they can provide their audience with the best experience.

Choosing a tripod projection screen is not too difficult when a person knows their needs.  It is easy to choose the size and style of tripod projection screen if a person understands the environment and audience size is a factor.  A tripod projections screen helps add to a presentation by allowing a person to give both audio and video information.

One of the best places to use a manual projection screen is in a classroom environment.  A manual screen is best for the classroom because it is easy to use and cost efficient.  A manual projection screen provides the right kind of convenience a teacher needs on a busy classroom environment.

One reason a manual projection screen is best for a classroom is because of the ease of use.  The screen can be mounted at the blackboard and pulled down when in use and put up when not in use.  The teachers class is centered around the blackboard so the students will already have a clear view of the screen.  Hanging it above the blackboard means the teacher does not have to do anything but turn around and pull the screen down.  There is no setting it up and adjusting it so everyone can see.

Another reason a manual projection screen is good for a classroom is because it is cost efficient.  Manual screens are the least expensive screen type and with schools budgets they can be purchased without money worries.  They are also cheaper to repair since there are no mechanical parts.

Manual projection screens are a great classroom tool.  They provide a convenient way for a teacher to give presentations.  They can be mounted for perfect viewing by the whole class and they are cost efficient.  Manual projection screens are something that help aid in education without breaking the schools budget and without being a burden to the teacher.

There are many different types of manual projection screens.  The one thing all manual projection screens have in common is that they must be raised and lowered by a person verses an automatic, motorized system.  Manual projection screens are much less expensive than the motorized counterparts.

A manual screen can be fixed or portable.  Fixed manual screens usually have a casing at the top where the screen is stored when it is rolled up and some sort of weight at the bottom, most often a strip of wood, that helps the screen stay open and flat.

The fixed screens are usually mounted on a wall and are meant to stay in the same place.  Portable screens are made the same way, but instead of being fixed to a wall they are set up on a tripod.  These screens can be taken from place to place as needed.

Manual projection screens work much like a flat blind.  They are held in place until a person chooses to release them.  Some have a hook at the bottom to ensure the screen does not roll up unintentionally.  When it is time to store the screen the person tugs lightly on the bottom and the screen rolls up into the casing.

Manual projection screens are often used in environments where the screen is going to be used often, but space is a concern.  These screen are easily stored and easy to use.  Manual projection screens work great for a person on a budget, too. They come in various materials and are very comparable to the more expensive motorized screens.
