Video walls are an increasingly popular display technology, widely utilized in environments such as control rooms, retail outlets, sports arenas, and corporate lobbies. Essentially, a video wall is comprised of multiple screens arranged in a matrix to form a single, large-scale, seamless image. Video walls are versatile and can either showcase a singular expansive image or multiple images, videos, and data sources concurrently. The complex task of managing and displaying content on a video wall necessitates specialized hardware and software components. Among these, two critical components are the video wall processor and controller. This article delves into the distinctions between the video wall processor and the controller.

Defining Video Wall Processor
A video wall processor is a dedicated hardware device designed to process video signals and route them to multiple screens, thereby creating a large, unified display. Video wall processors accept input from various sources like computers, cameras, media players, and video conferencing systems, and then adapt these inputs to fit the video wall's configuration. The processor addresses the resolution, aspect ratio, and orientation of each display and makes the necessary adjustments to the content.
Video wall processors are capable of executing a range of image processing tasks including scaling, cropping, and de-interlacing. 'Scaling' adjusts the resolution of the content to fit the display, while 'cropping' removes parts of the image outside the display boundaries. 'De-interlacing' converts interlaced video signals to progressive signals to eliminate flicker and enhance image quality.

Additionally, video wall processors can manage and split the content displayed on the video wall. For example, the processor can display a unified large image across multiple screens or segregate the image to show different content on each screen.
The X9 series Modular video wall processor exemplifies this versatility, offering flexible graphics processing and seamless switching. Designed with high-performance hardware, it supports a variety of high-definition digital and analog signal switching and processing. This system also features two-way RS-232, two-way IR signal switching functions, and the ability to divide a single image signal into several outputs. It's perfect for industries spanning from radio and television engineering to large-screen display setups, multimedia conference system, intelligent traffic management centers, command and control centers, and more.
Explaining Video Wall Controllers
A video wall controller, on the other hand, is a hardware device that governs the display settings of a video wall, such as brightness, contrast, color, and orientation. It ensures the image maintains uniformity across all screens and controls the overall appearance of the video wall.
Beyond adjusting display settings, video wall controllers manage the content shown on the video wall. They can switch between different sources, tweak the aspect ratio, and configure the layout. Overlays like logos and text can also be added to the content.
Video wall controllers can be operated through various interfaces including web-based control, remote control, or physical control panels. These interfaces allow users to adjust settings, switch sources, and manage displayed content efficiently.
Distinguishing Video Wall Processors from Controllers
The roles of video wall processors and controllers are distinct yet complementary. The processor focuses on content processing and adapting it to the video wall's configuration, while the controller is primarily concerned with managing display settings and overseeing content presentation.
Generally, a video wall processor is a hardware-centric device designed to handle the substantial processing power needed for managing video content. It can simultaneously manage multiple video signals and adjust them to fit the display arrangement. Conversely, a video wall controller is typically a software-based application running on a separate computer or embedded system, dedicated to controlling video wall settings and communicating with the processor for content management.
Functionality-wise, video wall processors excel at advanced image processing tasks like scaling, cropping, and de-interlacing, while controllers concentrate on display settings and content organization.

What Is a Video Wall Processor or Video Wall Controller?
Many organizations contemplating the implementation of a video wall processor may still debate its necessity and ROI. This discussion is prevalent as video walls, or multi-screen displays, gain traction in a variety of applications—from retail to hospitality, sports venues, educational settings, control rooms, and corporate boardrooms.
Despite the technical complexity of video walls, their increasing adoption boils down to a straightforward reason: they offer a versatile and dynamic solution for sharing information with diverse audiences, both large and small. Video walls facilitate the display of content from multiple sources and provide an immersive viewing experience, thereby enhancing information impact.
In addition to the screens, video walls require sophisticated technology for dynamic and flexible content management. This is where video wall processors come into play.
What is a Video Wall Processor or Video Wall Controller?
Essentially, a video wall processor (sometimes also termed a video wall controller) is software, often bundled with hardware, that allows the orchestration of content across multiple screens within a video wall as if they were a single canvas. It offers users the flexibility to display any content across multiple screens or the entire video wall and supports viewing multiple content pieces on various parts of the display concurrently. Each screen can be managed individually or in groups, offering a dynamic display solution tailored to diverse requirements while ensuring effective and impactful information delivery. Video wall sizes can vary hugely, from two to several hundred monitors, depending on audience needs.
Objective of a Video Wall Processor/Controller
Visualization systems need some technology to dictate what viewers see. Take air traffic management centers for instance: the more complex the system, the stronger the control framework needs to be. To fully leverage the capabilities of a multi-screen setup—optimizing performance, image quality, security, and automation—a video wall controller is indispensable.
However, not all video wall controllers are equal. The most effective ones enhance usability, offering an organization’s AV team or video wall operators the necessary tools to maximize the technology’s potential.
Advantages of Video Wall Processors (Video Wall Controllers)
No Resolution Constraints
Resolution is fundamental when discussing displays. More pixels equate to higher pixel density, resulting in sharper and more accurate images. Video wall controllers excel in producing visually striking effects. High-definition screens combined into a video wall can significantly boost resolution, enabling high-quality display without degradation, provided supported by a powerful video wall processor.
Handling Multiple Sources in Various Formats
Connecting and displaying multiple sources on a single projector or screen is often limited. Typically, they interface with a finite number of devices and can display a single source per screen at any time. A video wall processor eliminates these limitations, enabling multiple streams from different sources to be displayed in any configuration, size, or aspect ratio on the collective surface formed by the joined monitors.
Processing Capacity and Performance
High-end controllers offer additional features such as enabling internet access, live web sources, clocks, dashboards, and emergency messaging to be displayed collectively. They also support both baseband and IP sources, allowing for diverse content integration. Some units come with control panel designers for custom button creation on computers or tablets, simplifying layout changes on the video wall. A robust video wall controller ensures flexible configurations and peak processing performance for impactful visualization experiences.
