A video wall controller ( aka video wall processor) is a hardware and software device that allows the management of content on multiple monitors in a multi-monitor display or video wall, as a single canvas. A video wall controller gives users the flexibility to visualize any piece of content across a single screen, multiple screens or the entire video wall. It also allows for multiple pieces of content to be viewed on a single screen, a portion of the video wall or the entire wall, in any one of the unlimited possible combinations. Each display can be controlled individually or in groups, leading to a dynamic display solution that could be utilized to meet a wide range of display requirements while also delivering information effectively and compellingly. The number of monitors in a multi-monitor system can be as little as two displays to a hundred or even more.

Video Wall Controller Benefits

Resolution is a popular concept. It all comes down to the number of pixels available, we call this “display real estate”: the more pixels on a screen, the higher the pixel density, the more accurate and better the quality of image you will get. It’s easy to see why video wall controllers are very efficient at producing an impressive visual impact based on this flawed concept. When you build a video wall with a series of high-definition screens, the resolution increases incrementally. A video wall can only effectively display high-resolution content without quality degradation if it benefits the support of a powerful digital signal processing unit, i.e. a video wall controller.

Processing Various Sources

The connection and capacity to capture various sources on a single screen or projector is limited. They can interface with a limited number of devices and each screen can only display one specific source at a time. A video wall processor is needed to overcome these limitations so that a video wall can simultaneously display several streams from various sources and source types in any size, configuration or aspect ratio that is desired, across the single logical surface formed by the multiple monitors joined together.

Processing Performance

Professional high-end controllers bring many other additional benefits like the ability to enable internet access, allowing to display live web sources on the video wall or other apps, like clocks, dashboards, or emergency messaging, all at the same time. In addition to that, they can mix both baseband and IP sources and display them anywhere on the wall. Some even come with control panel designers that would allow you to design buttons on any computer or tablet that would permit users to change layouts on the video wall with a simple click of a button. The right video wall controller can deliver a high level of flexibility and achieve incredible processing performance, resulting in an infinite number of custom configurations for impactful and effective visualization experiences.
