How to bring out the best of your LED wall with a video processor

One investment that companies can make into their presentations is installing a LED wall with a video processor or controller. Although, there are options aside from video wall systems like individual large displays, monitors, or front projectors. Considering that they are all cheaper options than video wall processors, you would expect that organizations would prefer them. However, many companies face complex display option issues that can only be resolved with a spread of multi-displays forming a coherent video wall surface. In addition to this the new technology of LED walls give a perfect solution to display information over a large area built from multiple LED modules. All of these video wall solutions will require a central control unit to dynamically manage the monitors and that’s where a video processor comes in.

Video Processors

Multi-monitor displays can be operated whether in a group or independently with a video wall processor. This device makes it possible for the monitors to perform several presentation functions. Organizations, both for-profit and non-profit, can utilize this multi-monitor set up to pass across powerful messages creatively. With the possibility of having over 200 monitors in the setup, the need for a dynamic controller cannot be denied. Depending on the kinds of video wall systems you have in mind for your company, there are no restrictions to the level of complexity and flexibility that your multi-monitor setup can possess. You can review some of our top video processors and choose the ones that best serve your organization.

The Necessity of Video Processors for LED walls

During presentations that includes images/videos, it’s important that the speaker can manage the flow of the information. Not only does this help to keep the audience interested in the presentation, but it can also serve as a much-needed control mechanism in complex systems like air traffic control. Such kind of systems needs to have processors for the LED walls to provide superior flexibility compared to a single display. For instance, non-profit organizations that conduct presentations at different locations for separate companies will find video processors to be necessary to fully utilize the available display systems without any concerns.

As technology improves, these LED walls with video controllers are now incorporating smooth internet connections to improve the quality of content delivery. That function increases the ability of speakers/presenters to edit or prove some information by searching for answers on the web in real-time. Besides, the pixel per density per unit cost of a single display option exceeds that of a multi-monitor set up of similar sizes. And the individual units of the LED wall can be replaced to achieve the desired result in the presentation or to resolve a fault. The cost of replacement would be much higher for a single monitor fulfilling the same function.

Benefits of LED Walls with Video Processors

You can add many positive attributes to your LED wall system by incorporating a video processor. Here are some of their benefits;

1. Impressive Processing

Most LED wall systems are designed to rely on an external device, like a processor or controller, to do the major part of its video and image processing. Besides, these video controllers offer more functionality than built-in display control units. Because of their impressive processing abilities, these video wall controllers can improve the overall performance of the system. And that includes the resolution.

2. Processors Provide Higher Resolutions

As you increase the display constituent of your multi-monitor, you consequently improve the overall resolution of the video system. Compared to a single projector or display option, you can achieve higher resolutions with a LED video wall. Besides, they provide organizations with the option to expand their display surface since they can scale without losing quality.

3. They Provide More Flexibility for Presentations

LED-wall systems with video processors can display contents that come in diverse formats and resolutions. It can also accept content from many kinds of devices including cable boxes, computers, and cameras. The processor provides the flexibility to access a wide range of video or image sources, on a single platform. This is advantageous over simple presentation options like projectors which can access only specific content sources and cannot display all many of them at the same time. Besides the video wall processor allows the system to handle all the individual display units concurrently as one unit. It can also stretch and drag the content across the monitors. Depending on the efficiency of the software that works with the controller, your company will be able to layer, scale, crop, and zoom the content on the display screen. You may even be able to create custom presentations that can easily be automated with the video wall software.

4. Exceptional Brightness

LED video is designed to offer users brightness that is more enhanced than that of projectors and other single display options. This can come in handy when presenting content in areas of high ambient light so that viewers can see even minute details without squinting their eyes. These LED walls with the processor have improved contrast ratio unlike projectors, so they keep images sharp regardless of when they’re enlarged.

5. They are Resilient, Reliable and Versatile

Compared to single display options, LED walls with video processors show more reliability. Since they are made from high-grade video units, video walls can work for hours without end. And they do not require regular maintenance to continue providing the maximum reliability. The in-built controls and external controllers are resilient. While projectors are cheaper than LED walls with video processors., their long-term cost of maintenance is considerably greater. Some video walls require zero maintenance. Multi-monitors can be set up in different manners to achieve a wider range of shapes and sizes than projectors. Your company can get various designs that are 3-dimensional, curved, or non-rectangular. There are several mounting systems that you can employ for interesting designs like free-standing or wall-mounted. Video walls are highly versatile, so they can be set up to take up massive space or scaled to be portable.


From healthcare, sports, entertainment, to non-profits, many organizations stand a lot to gain from utilizing LED walls with video processors. Asides from the versatility they offer companies looking to creatively present their content to their audiences, these video processors offer increased functionality in terms of resolution, brightness and image-quality. Besides, multi-monitors are more resilient than single-display systems.
