Changes to Monitors Displayed on a Video Wall Controller

When setting up and managing a video wall, it can be very beneficial to have real-time visibility into what changes are being made to the monitors that make up the video wall. A video wall controller helps with this visibility by displaying on the monitor screen what changes are being made to the video wall setup. This helps when setting up different configurations of video walls or in troubleshooting any problems with the video wall setup.

Embedded System Design

In video wall systems, one large video wall screen is composed of smaller monitors. A video wall controller is responsible for the management and display of images on the video wall screen. The embedded system design of the controller must take into account the different capabilities of each type of monitor in the video wall system. For example, some monitors may have a higher resolution than others. The controller must be able to send the appropriate image signal to each monitor in order to create a seamless display on the video wall screen.

Video Wall Configuration

Video wall systems are becoming increasingly popular as they offer a high level of flexibility and functionality. A video wall controller is responsible for managing the display of content on a video wall. In this blog post, we’ll take a look at how changes to monitors can be made using a video wall controller.

Embedded System Components

The following are the embedded system components used in the Video Wall Controller sample:

– A processor (MPU)

– A real-time clock (RTC)

– A memory management unit (MMU)

– A power management unit (PMU)

– An interrupt controller (INTC)

– A direct memory access controller (DMAC)

– A Pulse Width Modulation timer (PWM timer)

Hardware Setup

You’ll need a computer with multiple monitors connected. The computer will act as the video wall controller. You can use any type of video cable to connect the monitors to the computer. We recommend using DVI, HDMI, or Display Port cables.

Testing Results

The first thing we noticed was that the displays were not updating as quickly as they should have been. After some investigation, we found that the video wall controller was not configured correctly. We made the necessary changes and the displays began updating correctly. However, we then noticed that the images were sometimes distorted. We again investigated and found that the refresh rate was set too low. We increased the refresh rate and the images displayed correctly. Finally, we tested to see if we could display different content on each monitor. We were successful and all monitors displayed different content.
