What format should my screen be?
The 5 common projection screen formats are:

AV Square Format - Where the width and drop are the same dimensions, this being a rarely used format except in educational facilities, which still use overhead projectors.

1 Unit Wide x 1 Unit High 

Video 4:3 Format - Which is the same shape as a traditional television and most computer monitor screens. Used primarily for corporate and education, which utilise a mix of computer and DVD presentations.

4 Units Wide x 3 Units High 

HDTV 16:9 Format - Fits nearly all DVD movies and is currently popular with new wide screen TV sets. This is the format for the dedicated Home Theatre.

16 Units Wide x 9 Units High 

 

16:10 Format - A newly created format that has become popular with laptop manufactures for their LCD screens, and due to the change in their graphic output, projector manufactures are releasing 16:10 chipped projectors for commerical environments. 

16 Units Wide x 10 Units High 

 

Cinemascope 2.35:1 - A long standing commerical theatre format, with the release of anamorphic lens technology allowing standard projectors to display a Cineascope image, this dedicated movie format has recently entered the mainstream home theatre scence.

2.35 Units Wide x 1 Unit High

What size screen do I need?
For single position viewing - such as most Home Theatres - it is an industry standard that the best screen size is determined as follows:

Measure the distance from the middle of the chair you will be seated in, to the proposed screen position, divide that distance by 3, and that is the correct approximate height of the projection screen - the format you choose will not alter this measurement, as the human eye has a very wide peripheral vision (side to side), it is top to bottom view that is the limiting factor to viewing comfort.

Now take into account the following:

Width of the room.
Depth of the room.
Suitable location for a projector.
The power and throw distance of the projector.
The bigger the screen the more powerful the projector needed.
Where you will be sitting to view the screen.

Now choose the nearest standard appropriate size or get Screen Technics to custom build exactly to your requirements, for which service carries no extra cost.

What is the 2 to 6 rule?
The 2 to 6 Rule is an accepted industry standard that assists in determining the best size projection screen when multiple row seating is in play, such as boardrooms or cinemas.

As follows:

The closest viewing position should be no more than 2 x the height of the screen, with the farthest viewing position being no less than 6 x the height.

Example

The closest viewer is 3m away from the screen, and the furthest viewer is 8m.

3m divided by 2 = 1.5m Maximum Screen Height
8m divided by 6 = 1.3m Minimum Screen Height

NB: Please consider 4 x height formula for 2.35:1 Cinemascope format 

Now consider the following:

Available Sizes
Site Conditions
Customer Requirements
Projector Characteristics

Work out the above details and the size needed will begin to come into focus, although if in doubt please call our customer service department on (02) 4869 2100 with the relevant details, and we will assist you with your decision.

Do I need extra leader - what is it?

What is Extra Leader?
Leader or Top Black Border is the amount of masked (painted black) material that resides above the white picture area on most roll down projection screens.
All quality projection screens in Video 4:3, HDVT 16:9, 16:10 and 2.35:1 format will have leader above the image area, as this lets you lower the image area down into the room to achieve a comfortable viewing position.

Why would I need extra?
Say you have a high ceiling and the standard leader length, which alters from product to product, still leaves the image area too high to be viewed with comfort, what do you do? - Order your screen with extra leader!

Whats the down side?
The more leader you have the worse your Lay-Flat becomes on the screen, so seek advice as to what is acceptable before technical problems arise.
It costs extra.
It cannot be ordered after the fact - you need to consider it at the time of purchase.
Because Screen Technics is a manufacturer - not an importer - we can accommodate these custom requirements.

Available leader for each screen is noted on this website, if you have any questions about the amount of leader you can purchase for a particular screen please contact the sales office.

What is gain and how much do I need?
Everyone thinks that High Gain makes your projection screen brighter - but this is just not true!

What High Gain does is re-direct the light towards a narrower viewing area, thus increasing brightness for the people sitting in that area, but decreasing it for the people either side of the middle viewers.

Hey that sounds great - well yes, it used to be great, back when projectors were quite underpowered and put out 250 to 400 ANSI lumen's of light (10 to 15 years ago), but now the norm even for cheap end projectors is 1200 plus ANSI lumen's and the requirement for High Gain (re-directed light) has all but disappeared in favour of Unity Gain (rated as near 1.0 Gain).

Why

High Gain Screens always had a Hotspot (bright circular centre) with fade off in brightness at the edges of the screen, which people used to put up with to achieve overall brightness, but with new powerful bright projectors, there is no need for brightness assistance, so why put up with the downside of Hotspotting!

Why Unity Gain 1.0

Unity Gain disperses the reflected light back in multiple directions, not focused, and this achieves evenness of brightness across the entire screen, from corner to corner, and has no artificial artifacts interfering with the projected image.

Please note that High Gain Screens can still have some limited commercial applications, seek advice.

Why are fixed frame screens the best?

Because they're FLAT!

The ultimate goal of all projection screens is to be as flat across the screen surface as possible, and no screen can beat a Fixed Frame Screen in this regards, as they are fully tensioned 360 degrees around the framing system and this creates a "Drum" effect - perfection!

Can I have a remote control for my screen?

Yes you can!

Obviously this question is only relevant to Motorised Roll Down Screens and there is a vast range available and most can be ordered to have some form of Remote Control System, there are two common styles of Remote Control.

Infra-red ( IR ) - Which by far the more common style in the audio visual world, but it requires a visible sensor in the room and "line of sight" aiming when in use, but it is the most easily integrated into other control systems or learn-able remotes.

Radio Frequency ( RF ) - Not as commonly used in the audio visual industry, due to lack of integration opportunities, but it has the advantage of no visible sensor in the room and no "line of sight" aiming of the transmitter.

There are also two physical styles available.

Stand Alone Box Controls - Meaning they are added as a separate control unit outside of the projection screen, normally stuffed into a ceiling space, and can be added to an existing installation if required latter on.

Integrated System - Which if ordered at the time of purchase allows an intelligent tubular motor to have a fully integrated remote built into your projection screen, with no extra control boxes to contend with.
They also offer a 3 pin plug for a normal GPO connection for power, whereas the Stand Alone option has 4 pin power requirements, needing an electrician to be involved with the installation.

Screen Technics ElectriCinema Range of Screens come standard with Integrated IR Remote Control, or can be specified with RF Remote Control as a same cost option.

Micro-perforated screens - what are they?

To experience true home cinema you require a surround sound system with five speakers strategically placed around the room, one of those, the centre channel speaker for mainly dialogue, ideally needs to be where the actors are speaking from - the screen.

The solution is often to place the speaker below the screen but you can actually place the speaker behind the screen by using a Micro Perforated screen surface which gives you whats called acoustic transparency and lets the sound through largely unimpeded. This is standard practice in all commercial cinemas, which uses very small perforations or holes in the screen for sounds to pass though, while being invisible to the viewer.

This can provide a solution to hiding at least one of those speakers in your lounge room while enjoying the thrill of a true surround sound experience. Screen Technics offers Micro Perforated screen surfaces on their fixed frame CinemaSnap systems.

How do I mount the screen in the ceiling?

You can always cut a hole in the ceiling and mount your screen up there in the dust, but if you want a professional finish - and who doesn't - then you have two great choices available from Screen Technics.

Interfit Screen Box

Purpose built in-ceiling unit that allows installation into the project at an earlier stage of construction, as the actual Projection Screen can be clipped in at a latter stage when the dust has settled from the building site. It has all the internal bracketing and prewiring capacity required for a smooth project.

Interfit Trapdoor Screen

The ultimate Home Theatre Screen, this unit hided in the ceiling until you hit the down button and an automated trapdoor opens, and the screen rolls down into view, ready for the movies - Luxury!

Please contact our sales department for advice as to which unit would best suit your requirements.

Can I link my projector to the screen?

Yes you can, by using an screen trigger device, which allows you to simply connect the power source for the screen and the projector, so that when you turn on and power up the projector, the screen automatically lowers into the set position, ready to go to the movies!

And when you turn off the projector up rolls the screen, no battling with multiple remotes or wall switches, just practical integration.

Triggers can either be linked by the low voltage output, most projectors have or directly through the main power point, so that this system allows virtually any projector on the market to link up with a Screen Technics motorised projection screen.

Please ensure that your retailer informs Screen Technics that you wish to utilise a screen trigger, as this may require a different motor specification, depending upon which screen model you choose - basically a 4 core motor is required.

Lay-flat... what does it mean?

The term Lay-Flat is a key screen industry term, that all quality manufacturers of projection screens are constantly thinking about!

To have good Lay-Flat qualities, a screen does not exhibit much in the way of waviness across the screen surface, offering a nice and flat projected image, some of the factors that effect Lay-Flat are:

Roll Down Screens cannot be as flat as Fixed Frame Screens

Thicker diametre Roll Down Screen Tubes enhance flatness

Projection Screens prefer to be wider than they are longer

Top Black Leader effects Lay-Flat, so extra leader length is detrimental

Pull Down Screens have progressively poorer Lay-Flat due to surface stretching

These are just some of the issues effecting the Lay-Flat qualities of Projection Screens and illustrate why it is worth paying extra, where possible, for superior product - like ours!

Can I use my screen in broad daylight?

Well..... Yes and No.

For the vast majority of Projection Screens, the entire theatre room should be as close to dark as possible, as ambient light will wash out the projected image to some extent, and the contrast (the difference between black and white) will diminish.

Projection Screens are not really an alternative to Televisions.

But there are products supplied by Screen Technics that can assist with ambient light conditions

Rear Projection Screens - When the projector is actually behind the screen in its own dark room and you are sitting in a well lit room on the other side from the screen.
This works well and is popular in corporate environments, but it does require a fair amount of real estate behind the screen and for that reason is rarely used in Home Theatre.

SuperNova Projection Screen - A totally new and revolutionary product manufactured in Denmark by DNP.
It is a solid acrylic screen designed for front projection in full ambient light conditions and if set up under under specified conditions can have an excellent result in such environments.

Information on both screen types can be found in our products section on the website.

What is side tensioning?

The aim of any quality projection screen is to have perfect Lay-Flat, or lack of surface waves, to present the projected image as clearly as possible.

But all Motorised and Manual Roll Down Projection Screens, by necessity, tightly wind their surface material around skinny tubes and thus create a problem for attaining good Lay-Flat qualities. The screen material rolls down with some waviness across the surface, this being an unavoidable feature of the roll down screen - well nearly unavoidable!

Side Tension Screens utilise a curved radius cut down the edge of the screen and support that edge with an elasticized cord connected to the screen at regular intervals, this pulls the screen outwards from the centre, vastly improving the Lay-Flat properties of the projection screen.

This can also assist in screens that require extra long top leaders, as this situation creates poor Lay-Flat also and the Side Tension System can really help this problem - Only available in Motorised ElectriCinema models.

Multi formatting - sounds good, what is it?

When selecting a screen one normally chooses a format shape, such as Video 4:3 or HDTV 16:9, and lives with the fact that should you wish to watch any other formats, that the screen will not have the correct black masking in place for a nice sharp edge to the projected image.

But what if you wanted 2 formats or 4 formats on the one screen, well this can be achieved by using Multi Formating screens, which use a series of motorised masking systems, either side or top to achieve the change in ratio formats from viewing one show to the next.

Which system you require is determined by how your projector handles the change in formats, either cropping them top and bottom or the sides. Once you have established this then you can choose the matching multi formating system for your projector.
Screen Technics produces a range of screens for this situation being the DualTech Formator Series 1 and 2 and the QuadTech Formator for those wanting 4 aspect ratios for the ultimate home theatre screen, all of which can be had in either roll down or fixed frame systems.
