Slide projector screens

Once you have a slide projector, even a digital projector, then a projector screen is usually the next item on the shopping list.  You can project directly onto plain walls, but unless they are completely smooth and matt white, the quality of the image is not going to be too good.

There are front and rear projection screens.  Front projection is where the slide or digital projector is in front of the screen near the audience.  If you think about most cinema's the projector is at the back of the cinema and the image is projected above people's heads to the front of the cinema room.  Rear projection is used where you don't want the audience to see the projector and the projector is actually behind the screen.  This gives the effect of a large TV type screen.  With slide projectors, front projection is the norm.

There are several type of projector screens.  Most people just think of the either tripod or wall screens, but there are now a lot of different options:

The traditional tripod projector screen Tripod screens

These are the traditional projector screen.  The great thing about these is that you can get a basic one for around £50+VAT.  The transport and storage of these screens can be a bit of a pain. 
A table top projector screen Table top screens

These come unfolded in neat, usually black, cases and are designed to be pulled up and sat on the top of desks.  These are normally small so are useful to travelling sales people and travelling presenters.  The good thing, compared with the tripod screen is that you can take one of these on public transport without difficultly.  The down side is that these are small screens for audiences up to about 10 people and cost on average around £100+VAT.
A pull up mobile screen Pull up mobile screens

Like the table top screens, these come in neat cases but are a lot larger for bigger audiences.  The case is put on the floor and then the screen is pulled up so this is free standing.  These look a lot neater that tripod screens and one nice thing is that they you can put them flat against wall.  If you have ever tried to put a tripod screen next to a wall, you know that the feet stick out and that they are a pain.
An example of a pull down wall screen Pull down wall screens and electric screens

Pull down screens are designed to be attached to walls.  The case is screwed to the wall at the top and then the screen can be pulled down into position when required.  A small basic screen can be purchased for around £50+VAT

Electric screens work the same way but usually there is a switch mounted near the screen and this can be used to automatically raise or lower the screen.  This is useful when the screen is in a high, inaccessible area, such as a screen attached to a rafter in a church.   There start at around the £175+VAT mark.
A fixed frame screen Fixed frame screens

These are wall mounted screens that look a bit like picture frames.  These can give a nicer look in places like board rooms, but cannot be retracted like pull down wall or electric screens.  Prices start at £125+VAT.
A mobile frame screen Mobile frame screens

There are front and rear projection versions of these.  These are generally really large screens that you would use in large areas such as auditoriums where you want a really large temporary screen that can be transported between venues.  You have to build up screen screen's frame with a series of poles, in much the same way you would a tent, and then attached the screen material.  Usually, these are supplied in a nice case.  Prices start at over £500+VAT.

In the above comparison chart, there are a few terms that need explaining.  The Aspect ratio is the shape of the screen.  An aspect ratio of 1:1 is a square screen.   For example, a 100cm x 100cm screen (100cm width by 100cm in height) would be 1:1.  The most common aspect ratios are 4:3, which is the shape of a non-widescreen TV, and 16:9 which is the shape of a widescreen television.  Tension refers to 'Tab tention' which is where the screen fabic is stretched to give a really flat surface, which is only generally in really expensive screens. 

A quick note about the 'keystone' effect.  If you position a projector in front a screen and it is pointing upwards toward a screen then you end up with an image that is wider at the top than at the bottom.  This is the keystone effect.  Many screens have a keystone bar that the top so that the screen can be angled to get rid of this.  Some screens have an optional bracket for this.
