Choosing the video projection screen p.1/2

It’s hard to live the real Home Theater experience without the video projection screen that enhances the video projector image quality.
Some users sometimes wonder whether a projection screen is really necessary in a home screening room system. We provide you with some essential information that will help you gasp the real benefit of this (too often seen as an option) element. What’s more, you’ll learn how to choose your video projection screen.

Video projector screen’s mission

The main goal of a projection screen if of course enhancing the screened image. However, beyond this final mission, let’s focus on the technical aspect of the fabric.
If you want the projected image to be perfectly clear-cut, the fabric’s surface needs to be completely smooth. That’s the secret of uniformly clear display.

Recreating the original colors of the screened image is another role of the projection screen. Pure white and smooth surface is required to enhance the colorimetry. The “pure white” (also known as matte white) comes from the Magnesium Carbonate mineral. It can be measured by the “gain” factor range. A screen with a gain of 1.0 is considered pure white.
Anyway, enough of technical details for today.

Now that you know the real function of the video projection screen, let’s got straight to the point : how to choose your projection screen.

 

Type and frequency of the video projection screen use

In order to determine what kind of video projection screen is perfectly adapted to your project, you should think about how and how often you are going to use it.

If you’re lucky enough to have a room that will be transformed into a Home Theater, a fixed frame screen would be the best choice. This type of screen guarantees the perfect screen flatness because the fabric is always stretched over the frame. However, it will always be visible. If you plan setting up a Home Cinema system in the living room as, you should probably opt for an electric projection screen.

Choosing your electric video projection screen

An electric video projection screen consists of 3 essential elements that define its quality:

  • the fabric
  • the motorization system
  • the carter (video projection screen case)

The fabric

There are two types of fabric material used in video projection screens production.

Vinyl video projection fabrics

This type of fabric is made of PVC (or polyvinyl chloride to be more exact [plastic like material to be less exact]). The production cost is relatively low and it’s most efficient when the screen frame is fixed and the fabric is stretched over it.
On the other hand, if the screen doesn’t allow the fabric to be stretched enough (this concerns electric video projection screens), the fabric slackens over the time. This is where the wrinkles and bulges come from. You must have already been in a meeting room equipped with a low-quality video projection screen.

Fiber glass fabrics

This kind of fabric is made up of three different layers : matte white layer for the image reflection; the fiber glass layer that naturally helps to maintain the fabric which prevents it from slackening. The last black layer is placed at the back of the screen. It makes the screen lightproof and avoids any video projector light flow “leak”. Thus, the fiber glass fabrics are more expensive because of the much longer and more complex manufacturing process but the quality is worth the price.

You’ll find an infinite number of fabric varieties from different producers online. They often have a very specific use (very light environment for example).
If you think you will probably watch movies in the dark (with the lights off and certainly not in the daylight) the 1.0 gain video projection fabric is the best choice.
If, however, you plan using your video projector in a highly bright environment, you have two choices: you opt for a video projector more powerful than the traditional ones or choose light rejecting fabrics. Useful but expensive, Screen Innovation screens cost at least 1 500€ (even the smallest).

Electric video projection screen motorization system

The motor is quite often neglected while looking for the perfect video projection screen. Yet, this essential element needs to be taken into account for it determines the speed and the noise level of the electric video projection screen.
It’s really important because the muffed sound that you hear when turning your video projection screen on and off may be really frustrating. Especially after spending a little fortune on transforming your living room into a Home Theater. Compare this feature among different screen models (measured in rpm as well as in dB).

Electric video projection screen case

In addition to design, which is indeed important for both an electric projection screen and a recessed video projection screen, here come other elements to think of while choosing your ideal video projection screen.

Projection screen’s attachment system

There are almost as many attachment systems as video projection screens. Some of them are more complex than others and provide faster and easier setting up process solutions. If consider yourself a decent handyman or your installer isn’t very expensive you can use a basic attachment system. However, if you wish the installation process to be simple and quick, the modular attachment system would be of great help. Our Concept Electrol video projection screen uses precisely this attachment system.
This is a very important aspect of recessed video projection screens embedded in the false-ceiling too. In this case, the most adequate attachment system is compatible with the plaster suspended ceiling (BA13) just like our recessed electric video projection screen Concept Built-In Electrol.

Your electric video projection screen’s volume

Unlike the USA, where there’s plenty of room for basically anything, the old good Europe requires much more compact solutions. You should probably check the projection screen case to the fabric’s size ratio.
Some producers manufacture cases with one end longer than the other. Just like over sized cases, this type of video projection screen mind ruin your interior decor.
This issue concerns on-ceiling electric video projection screens as well as the recessed ones.
