Understanding Video Wall Controllers & How They Work

Have you ever attended a live event with a massive LED screen made up of numerous panels around the stage or as a backdrop? If so, you have likely seen a video wall controller in action without even knowing it.

As a top supplier of Video Wall Processors and Controllers , we are your one-stop destination for all your needs. Our highly-specialized staff can assist you in finding the perfect product for your requirements.

What is a Video Wall Controller and Why Do You Need One?

Also referred to as a video wall processor, a video wall controller is essential for properly displaying images on a video wall made up of multiple panels. It splits the image into segments suitable for each panel, thereby preventing the tiled effect where each panel shows different content.

The processor functions as a regulator ensuring that each content piece arrives and displays as intended, seamlessly forming one large image. Smaller displays might use a multi-monitor video card instead, but larger setups, such as curved video walls, necessitate a video wall controller.

What Type of Controller Do You Need?

The type of controller you need depends on your specific project. Video wall processors come in both hardware and software variants, each offering its own set of advantages and limitations.

You must ensure that your controller can meet the screen size demands you have. For example, the Magnimage LED-550DS LED Video processor is ideal for larger events like theatre or live music performances. It supports oversized LED screens with seamless splicing using a DVI loop interface.

If you intend to show online content, look for a processor with a web server interface for easier firmware updates. For more detailed recommendations, discussing your needs with technical experts is advisable.

What Types of Video Wall Processors Are Available?

When considering a 4K video wall, several crucial factors must be considered. Here, we will explore what a video wall is, the technology behind it, and the four different types of video walls suitable for diverse applications.

What is a Video Wall?

A video wall is a multi-display arrangement that projects a larger image or multiple images through connected screens. This can include LCD or LED panels, tiles, cubes, or projection screens. Video walls offer flexibility, control, scalability, and creativity, ranging from a single source image stretched across multiple screens to more complex configurations.

Display Screens

When planning your video wall, consider the type of display you want to use, such as LED and LCD panels, tiles, cubes, or projector systems. Brightness and resolution vary among displays, affecting the detail and clarity you achieve. Additionally, consider the bezel width, as newer monitors with ultra-narrow bezels provide a more perfect image.

Video Wall Processors

Today, the terms video wall processor and video wall controller are often used interchangeably. The main role of these devices is to split video content across displays on a multi-display wall, ensuring each source signal reaches the correct screen at the right resolution. Video processors acquire an image and seamlessly distribute it to form one cohesive image.

Advanced video wall processors can manage content from multiple sources and display it across different screens, similar to traditional video scalers but with enhanced input, output, and processing capability.

Video Scalers

Sometimes, video wall processors are located close to displays and connected via video cables. In other cases, especially when processors are in server or IT rooms far from the display, a video extender is needed. For distances as short as 30 feet, an extender might be required; some IP-based systems use small receivers behind monitors, transmitting the signal over LAN without needing additional video extension.

Advanced Video Walls

Advanced video walls support a variety of configurations and provide a dynamic, canvas-style user interface for adjusting content windows. These processors can handle numerous screens and multiple video inputs, including local IP stream decoding to display content from IP-based security cameras or other remote sources. They can also encode video sources for sharing with other sites or users. Commonly found in mission-critical control rooms, these video walls need to be operational 24/7.

When selecting the appropriate video wall for your needs, consider its intended use: digital signage, control room displays, or something in-between, and the environment in which it will operate: military, security, utilities, retail, education, transportation, museums, industrial, conference rooms, etc.
