If you’ve ever been to a live event where there has been a large LED screen comprised of multiple panels flanking the stage or comprising the backdrop, then you’ve probably witnessed a video wall controller in action without realising it.
The company is the world’s best Video Wall Processors and Controllers supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.
What is a video wall controller and why do I need one?
Also known as a video wall processor, a video wall controller, simply put splits the image into parts to be displayed on each individual panel of the video wall, so the full visualisation can be displayed correctly over the many panels of the screen. Without one, you would simply have a tiled effect with each panel displaying something different.
The processor acts as a regulator, ensuring that each bit of content arrives and is displayed on the panel that it is intended to create a large seamless image. Some smaller displays may not need a processor, instead, they rely on a multi-monitor video card. However, in the case of large video walls such as curved video wall banks, they will require a video wall controller.
What type of controller will I need?
The simple answer is, it depends on the project. Many processors are now available in both hardware and software versions and each one of these will come with its own benefits and limitations.
You need to make sure that your controller can handle the demands of the screen size you intend to use it for. For example, controllers like the Magnimage LED-550DS LED Video processor are ideal for larger-scale events, like theatre or live music events, where a large video wall is a necessity. This controller supports oversized LED screens with seamless splicing through a DVI loop interface.
If you plan to show online content on your video wall then look for a processor with a web server interface. Incidentally, this will also make firmware updates easier.
However, the easiest option to take when it comes to selecting the correct controller is to contact the technical wizards at Hybrid AV and discuss your requirements.

When considering investing in a 4K video wall, there are some important factors you need to keep in mind. In this guide, we'll take a look at what a video wall is, some of the technology behind it, and the four types of video walls used for different applications ranging from basic to complex.
What is a video wall?
A video wall is a type of multi-display wall that displays a larger image or windows of multiple images by connecting multiple screens together. The display technology can be LCD or LED panels, tiles, cubes or projection screens. A video wall can be as simple as one image from a single source stretched across multiple screens. These types of video walls offer greater flexibility, control, scalability and creativity.
Display Screens
When planning your video wall, consider what type of display you want to use. You can choose from LED and LCD panels, tiles, cubes and projector systems. Not all displays have the same brightness or resolution, and these specifications are likely to be important decision criteria. The more detail and clarity you require, the higher the resolution you'll need. You also need to consider the width of the monitor's bezel. Newer monitors have ultra-narrow bezels, resulting in a perfect image.

Video Wall Processors
Today, the terms video wall processor and video wall controller are often used interchangeably. Their basic job is to split the video content for each display in a multi-display wall. A video wall processor is a video scaler that ensures that each source signal goes to the correct screen at the correct resolution. It acquires the image and sends it to each screen to be displayed as one large, cohesive image. The video processor is responsible for taking the various inputs and putting them together. An advanced video wall processor can take content from multiple sources and display it on multiple screens. A video wall processor is similar to a traditional video scaler, but with greater input, output and processing power.

Video Scalers
Sometimes, video wall processors can be located close to the display and can be connected directly via video cable. In other applications, video wall processors may need to be located in server rooms or IT rooms that are too far away to use standard video cables. In these cases, a video extender is required to transmit the video signal from the video wall processor to the display. For cable distances as short as 30 feet, a video extender may be required. Some IP-based systems use small receivers (one per monitor) that can be mounted on the back of the monitor. In these cases, signal extension is done over the LAN and no additional video extension is required.
Advanced Video Walls
Advanced video walls are screens that support a large number of different form factors (e.g., 3x2, 3x4, 6x4, etc.) and provide a canvas-style user and display interface on which many content windows can be dynamically moved or adjusted. Advanced video wall processors typically support dozens of screens and many types of video inputs. These types of video wall processors can also support local decoding of IP streams to display a large number of streams from devices such as IP-based security cameras or other remote sources. Some are also capable of encoding video sources to be shared with other sites or users. Advanced video walls are found in mission-critical control rooms that need to be up and running 24/7.
When considering which type of video wall fits your unique needs, you first need to consider how you intend to use the video wall. Do you want a simple digital signage type display, a large state-of-the-art control room wall or something in between? What environment will the video wall be used in: military/tactical, security, utilities, retail, education, transportation, museums, industrial, conference rooms, etc.
