Terms used in our projector screens comparison charts



If you are new to projector screens, then please read our Quick guide to projector screens.  

Type

These are just short codes in the comparison charts and will be one of the following:
Example picture Type Description
     
Medium 150  x 110 manual wall screen Electric A wall or ceiling mounted electric screen.  The screen is rolled up or down automatically by either a wall switch or via a remote control.
Sapphire RapidFold 203  x 114  fast fold screen Front mobile These are high end mobile screens that are transported in their own flight case and made up of a series of poles to form a frame that the projection fabic is attached to.  "Front mobile" are front projection screens, which means that the projector is placed in front of the screen with the audience.
Sapphire RapidFold 203  x 114  fast fold screen Rear mobile Same as the front mobile, except using rear projection.  This is were the projector is behind the screen so that the audience doesn't see it.
Medium 171 x 128 fixed frame rear screen 1.7m Fixed frame A fixed sized screen that is installed on a wall and gives a 'picture frame' appearance to the projected image.
Pull up mobile This is the modern replacement for the old fashioned tripod screen.  These arrive in a long metal case and then you unlock them and pull the screen up and out to use it. 
Table top A screen designed for table or desk top use.  Ideal for travelling presenters who are presenting to small audiences up to 6 people
Screenlabs 127 x 127 tripod screen Tripod The traditional tripod screens which store neatly away and when you want to use them you fold them out, extend the 3 legs and roll up the projector screen.  These are the lowest cost type of portable screen.
Medium 150  x 110 manual wall screen Wall and ceiling Designed to be permanently mounted on either a wall or ceiling.  The projector screen fabric is on a roll in a metal case and is pulled down when in use.


Width and height

This is the screen width and height in centimeters.


Aspect ratio

This is a fancy term for the shape of the screen.  There are 4 basic shapes:

Screenlabs 127 x 127 tripod screen Sapphire RapidFold 203  x 114  fast fold screen Medium 171 x 128 fixed frame rear screen 1.7m Medium 171 x 128 fixed frame rear screen 1.7m
Square (1:1 aspect ratio) Normal (4:3 aspect ratio) Widescreen (16:9 aspect ratio) Widescreen (16:10 aspect ratio)

You should aim to match the shape of the screen to the shape of the image of your projector.  So if it is a widescreen projector, go for a widescreen projector screen.  Most widescreen projectors are now 16:9 as that is the shape of True HD.  16:10 was used for widescreen computer monitors before HD video was out.


Diag (diagonal) inch

The diagonal screen size in inches.  Most TV's and computer monitors are messured in diagonal inches and it is sometimes easier to visualise the size of a screen this way.  For example, if you have a 50" plasma TV at home and you are looking at a 50" projector screen, you will be able to picture this easily.


Pro (projection) type

This is either FRONT or REAR.  Front projection is where the projector is in front of the screen near the audience.  Most cinemas use front projection.  Picture your cinema.  The projector is in a booth at the back of the room shining forwards over the heads of the audience onto the screen.  Rear projection is where the projector is behind the screen and uses special rear projection fabric.  There has to be a space behind the screen so that the projector can sit far enough away to project an image that fills the screen. 


Tension

Some screens have a system called 'tab tension' that stretches the projector screen fabric really tight so that you get a really flat surface.


Surface

This is the type of screen fabic used.  Most screens are just 'Matt white'.
