There are different approaches to

implementing a video wall, and usually

people looking at deploying one are not

too clear on what will fit best their project.

Video wall controllers provide more power

and flexibility to a video wall deployment;

but they used to be substantially more

costly— although there are solutions

nowadays that have made them more

affordable (for example the Userful video

wall solution). In this article we want to

shed some light on the situations where

having a video wall controller would be

very beneficial for a deployment.

Video Wall Controllers vs. Video Wall Scalers

Video wall scalers (or matrix scalers) offer a simple way to split a single video stream into multiple outputs, but

they are generally limited in both resolution—with even the best scalers supporting only 1080p, and 4k at most

—and layout options—many are limited to juts grid configurations. Many high-end, zero bezel displays include

built-in scalers, though end users are “forced” into using only compatible displays within a supported

arrangement. Matrix scalers are usually limited to a single source, and many can’t handle irregular aspect

ratios (i.e. 1x5, 1x10 configurations, etc.), and those that do are still limited to the original source resolution,

and look very poor quality.

Video wall controllers, on the other hand, address many of the limitations in matrix scalers. The Userful video

wall solution, for example, supports ultra high source content resolutions (up to 8k), allows multiple

simultaneous content sources (supporting real time content, interactive content, and managed content), and

even support artistic, mosaic-style, video walls with unique designs and highly irregular aspect ratios, while still

showing ultra high quality images. Userful also provides an intuitive browser-based graphical interface for

management and configuration, with advance features that allow for more dynamic and interactive video walls.

How do I know if my project needs a Video Wall Controller?

If a deployment requires showcasing multiple content

simultaneously (i.e. a mix of HTML5, live TV, videos, web

content, etc.), or switching easily between content sources,

that is a good indicative that a video wall controller is

needed. For example, control and command centers,

where multiple content is on display—live camera feeds,

interactive maps, desktop environment with analysis

applications, etc.), would require a video wall controller.

With Userful’s solution users can establish preset zones

within their video walls and allocate different sources to

each section, and switch configurations “on-the-fly” from

the web GUI.

Affordability in Video Wall Controllers

Traditional, video card based video wall controllers often cost up to $50,000 (or even as much as $100,000),

and are usually complex to configure and maintain. These generally consist of proprietary, specialized

hardware and software, and makes users depend on a sole vendor when it comes to setup, troubleshooting,

RMA, which may cause delays due to low availability.

Userful’s software-based video wall eliminates these problems by transforming a standard PC (available from

a variety of vendors and manufacturers) into a high performing video wall controller, with a simple and flexible

configuration interface that includes advanced features, such as pixel perfect alignment, display color

calibration, bezel correction, and more. Purchasing a video wall controller won’t blow the budget anymore, it

can actually save you money by reducing the cost of the displays.
