You’ve probably already had your attention captured by Video Walls. After all, they progressively conquer space in companies, banks, schools and stores. If you want to know more about this technology, check out this article and find out how to start your project.
What is Video Wall?
If you haven’t read our feature on digital signage, this technology consists of a network of centrally managed and programmable digital screens for displaying information, entertainment, merchandising and advertising.
The Video Wall is commonly called the Display Wall. It is a form of digital signage in which two or more screens are used close together to give the impression of being just a much larger screen. With creativity, you explore the various visual possibilities that more than one screen provides.
There are several formats, including:
Square matrix: In this format, the number of columns and rows is equivalent to the number of screens. For example, 3X3, 4X4, 5X5 and so on.
Portrait or portrait: As the name implies, this format resembles a portrait. It is possible to have more than one column of screens; however, the number of lines will always be more significant to cause a vertical screen.
Landscape: From the English “panorama”, this format is the opposite of portrait. The number of rows will be less than the number of columns to print a widescreen.
Mosaic: As the name implies, the union of the screens will form a mosaic. In this format, several monitors are allocated irregularly. It is worth noting that this format requires its Video wall processing software to configure the video in a synchronized way.
How Does It Work?
For a Video Wall project to be fully executed, only the screens that will display the programmed images or videos are not enough. Other equipment perform functions as necessary as televisions.
The video processor, also known as a Video Wall distributor or controller, is an essential piece of equipment. This processor can be built into professional displays. It can be a specific standalone device, a mini PC with one or more video cards, or a high-performance system.
This processor will interpret the received video signal, cut the regions of the image that each screen should display, reassemble the video protocol for the different parts, and send them to each of the screens that make up the Video Wall. All functions occur synchronously to achieve the effect of a single screen. Due to the complexity of the process, it is not possible to create a Video Wall using only video splitters or splitters.
Types of Borders and Screens
The types of borders and screens that will be used in your Video Wall project are of utmost importance. All monitors must be the same size and resolution. Otherwise, the image quality may decay from one screen to another, nullifying the effect of a single screen.
Another essential aspect is the edges of the TV. The thinner the monitor’s edge, the less “break” from one screen to another, that is, the greater the effect of a single screen. Therefore, to ensure the success of your project, use televisions with thinner edges (borderless monitors).
Video Wall with Borderless Monitors
It is worth noting that borders are as crucial as screen resolution. Borders are more visual, and ample space between screens can make it feel like you see a cropped image.
How to Assemble: Use of Professional Screens
This option is the most recommended because of its high performance. Several professional models of LFD (short for large format display) monitors already have the video wall processor built into the screens with the Video Wall function.
The number of businesses that bet on digital signage is continuously growing. In this way, the value of screens becomes increasingly accessible, and the market has screens with a wide range of sizes. The LFD monitor has several advantages when compared to a home screen. Among them, the following stand out:
- Specific supports for Video Wall;
- Thorough colour calibration to prevent differences between screens;
- Much thinner edges;
- High brightness for exemplary performance in brighter environments (ideal for out of home digital media ) ;
- Hardware development to run 24/7 and superior lifespan; Home TVs are generally designed to run 6 to 8 hours a day.
Last Suggestion Before purchasing a video display wall controller, check the model specifications to ensure it will meet the requirements you are looking for.
