Videowall and graphic controllers: boosting efficiency in control centers

Traditionally, the videowall has been a tool dedicated to displaying information in professional environments or control rooms, but nowadays it is used in various environments with a wide variety of applications, such as advertising, corporate presentations or live broadcasts of sport events. The videowall is a vertical surface made up of multiple individual screens that combine to create a single large image.

Graphics drivers, what do they consist of?

A videowall is always controlled by an electronic device that usually has several graphic outputs to handle the visual data of the wall, which are known as videowall graphics controllers and are responsible for processing and distributing the content across multiple individual displays to create a single large image.

These drivers allow users to configure and customize the layout of the screens, the content displayed and the image quality, thus guaranteeing an optimal viewing experience for users. Additionally, some graphics drivers offer advanced options such as remote management and playback of multiple video sources in real time. For all this, they are a very valuable and essential tool for presenting information in large spaces, since they offer an effective and powerful way to manage and control the display of content.

There are several types of controllers depending on their processing capacity, typology and format, which offer different levels of customization and configuration:

1. Thin Client: These drivers are designed for standard videowall configurations. They are low-power devices that offer high performance and flexibility since they are highly scalable and can be easily integrated with different types of displays and content management software. In addition, they currently have the capacity to generate up to 4 outputs in 4K resolution, such as the GESAB DataWall DTW5732 unit, which allows serving compositions of up to 8×2 or 4×3, among many others.

2. PC: They use a traditional computer to control the videowall. These controllers offer a high level of customization and flexibility as they can be configured to suit a wide variety of user needs, especially for those videowalls that require high processing and storage capacity.

3. Chasis: They are ideal for large format videowalls, as they can have several slots for video cards, allowing a greater number of outputs, physical input cards and decoder cards. These controllers are designed to be rack-mounted and offer greater processing and storage capacity than others.

When grid and layout management is the basis

Every graphics controller must allow the composition of grids, dividing the screen into windows to display different content sources, such as live video feeds, real-time data sources, PCs, SCADAs and even access to web pages. In addition to making it easy to switch layouts so that users can adjust the screen layout according to their needs and preferences, changing the size and position of content sources and creating custom layouts.

Content source management is another important feature of the graphics controller that makes it easy for users to select and manage the sources they want to show or hide according to their needs. Some controllers even allow remote control from a computer or mobile device through HTML access, as is the case with DataWall, which has an integrated WebServer.

Managing the videowall from the station of the operator is crucial for its correct operation and quick response in the most critical environments. Operators must be able to configure, control and supervise the display of content and the sources that launch it on screens in an easy, agile and intuitive way.

Innovative applications that transform the work environment

Technological advances in graphics controllers are transforming the way we interact with visual information, simplifying display systems and improving information understanding and decision-making efficiency.

One of the most notable innovations is the integration of these controllers with dynamic KVM systems in a single ecosystem, such as DeskWall, which allows users to control and access multiple video and data sources from a single workstation. This makes it easy to view and control information from multiple sources in real time, including the videowall controller, improving productivity and efficiency in collaborative environments.

Another innovation is the use of Natural User Interfaces (NUI), based on much more intuitive and natural ways of interacting with technology, such as gestures or even voice. For example, in the DataWall, remote control interface, drag and drop functionality allows for easy organization and distribution of content across screens.

Finally, the trend of using APIs for communication with external systems is gaining momentum, as they provide a standardized way of communication between the videowall controller and other systems, such as building management systems, security systems or automation systems. This gives operators and administrators greater flexibility and control over the videowall, improving automation and optimization of operations based on external conditions and events.

Videowall graphics controllers and the aforementioned technology trends are revolutionizing the way we interact with visual information. These tools allow for greater flexibility, customization, and efficiency in content presentation, resulting in an improved user experience and more effective decision making. As technology continues to advance we can expect more innovations in this field, providing even more powerful and accessible solutions for a wide variety of applications and environments.
