If you are looking for a projector screen it is because you too are one of those people who have stopped thinking about television as the only way to enjoy a good movie. The habit of buying 40, 50 or even 60-inch devices is no longer so widespread. Nowadays, in fact, with a good projector, you can get amazing results.
The world of cinema and entertainment have found in projector and projection screens a new way of transmitting their images. This is due to the fact that these devices are able to offer the same audio and video quality as a modern television. If you are not familiar with this technology, continue reading to find out everything you need to know about projector screens.
With the right projector screen you can enjoy optimal quality when watching your films, but also at presentations and all occasions where you need to impress your audience with impeccable picture quality. Once you're clear on the main things to look out for, take a look at Hi-Fi Tower our product gallery, and find the projector screen with the size and features you need.
Projector screens are installations that you can mount in anywhere to create a sort of cinema, i.e. to project on them any multimedia content you want. Projector screens are manufactured in such a way that they do not allow light reflection, thus preventing image quality from being adversely affected. These devices have different sizes, shapes and modes of use, and each offers a different display standard (or format) and can be installed in various locations in any house or room. It all depends on the space you have available. In addition, there are many accessories to enhance the projection experience, such as speaker stands and mounts, tripods, cables and accessories.
A projector screen has a flat surface, usually made of canvas or derivatives, which is used to show images or films to an audience. In order to work, you need a projector that emits the above images or videos. Projector screens are used as permanent installations in cinemas and theatres, while a portable projector screen is designed to maximise the ease of transport.
The projection on the canvas usually takes place in a frontal direction, although there are models that allow rear projection. The colours used are almost always white or grey, in order to avoid discolouration of the original images. Although most projector screens are flat surfaces, there are also curved screens that are better suited to certain projector lenses.
At first glance, projection screens may all look the same, but although most are white and made of natural polyester, there are some aspects that make them different. In essence, the screens differ in gain, brightness and acoustic transparency. In the following table, we go on to better analyse these characteristics.
|Projector screen feature||What does it consist in?|
|Gain||This value defines the performance of the screen.
A low gain indicates a greater viewing angle, so it doesn't matter where you are sitting.
If the gain is high, the brightness will concentrate in the centre of the screen: this means that the person in front will enjoy a better sight
|Brightness||It is measured in LUX and indicates the contrast ratio of the projected image
The higher the contrast between the canvas and the background beyond it, the higher the image quality will be.
|Acoustic transparency||It indicates the ability of the screen to absorb sound and make sure it doesn't "bounce"
Many screens have very small holes in them to provide greater transparency and therefore improve sound quality.
Although they are very different from an aesthetic point of view, there are not really big differences between flat and curved projector screens. The main characteristic of the latter, which are more recent, is that the arc they form avoids the image distortion caused by the projector, which will be at the same distance from any point on the screen.
Fans of curved screens claim that each point of these accessories is at the same distance from the viewer's eyes due to the enveloping effect of the curve, therefore generating a more immersive experience. The detractors, on the other hand, claim that the curvature generates a strange perception, like that of a 3D effect.
This is probably the first question we ask ourselves. As we saw earlier, the aspect ratio is more important than the dimensions. In general, the projector allows us to see an image of up to 300 inches. However, this does not mean that screens need to be as large as possible. If you are going to install a projection screen at home, the ideal would be that its height does not exceed one-sixth of the distance between the screen and the place where you are going to sit. So, for example, if you sit at a distance of 250 centimetres from the screen, a 100 inches projector screen will work just fine.
Absolutely not. Using a wall to project images or videos has no advantage over a screen. This applies regardless of the type of wall you use: even when the wall is very white and particularly smooth, it is not the ideal medium for using a projector. The same applies to white sheets, even if they are made of the finest silk.
The materials used to make projector screens are specifically designed not to bounce light, to eliminate annoying reflections and to maintain image sharpness and definition. White walls or sheets may work if there is no alternative, but the quality of the result will be significantly lower.
