Overview

MAWi can work together with OBS Studio and the OBS Remote web application to provide flexible, browser-based control over a video wall.

This setup allows operators to control what appears on the MAWi video wall from any PC on the same local network. It is especially useful for control rooms, NOCs, SOCs, command centers, monitoring centers, showrooms, and other professional video wall environments.

Using OBS Studio, you can prepare and manage different visual sources, such as browser dashboards, applications, camera feeds, videos, images, presentations, and monitoring systems.

Requirements

Before starting, make sure you have:

• MAWi installed and configured
• MAWi Player v2 devices, if using standard display screens
• A Windows PC running as the main MAWi / OBS computer
• OBS Studio installed on the main computer
• OBS Remote web app
• All relevant devices connected to the same local network
• Access to the MAWi Display Config Tool

Step 1 - Create the Video Wall Layout in MAWi

Start by creating your video wall layout in MAWi.

In this example, we are using a 2x2 video wall grid.

Each screen is connected to a MAWi Player v2 device. The main computer identifies each connected MAWi Player as an extended monitor in Windows OS.

Once the screens are detected, assign each display to its correct position in MAWi.

Next, open the Display Config Tool.

Set the layout to 2 rows and 2 columns, arrange the screens according to their physical position, and confirm that each display is mapped correctly.

Once the layout is configured, the MAWi video wall is ready to receive content from OBS Studio.

Note for LED Video Walls

For LED video walls, you can usually skip the MAWi Player v2 layout setup, since the LED controller handles the screen mapping internally.

In this case, move directly to setting up OBS Studio for your video wall layout.

Step 2 - Install and Configure OBS Studio

Install OBS Studio on the main computer.

During the installation process, click Yes through the prompts until the installation is complete.

When OBS opens for the first time, select:

“I will only be using it for virtual cameras”

Then click:

Apply Settings

Next, set the video output resolution according to your video wall layout.

For example, if your 2x2 video wall uses four Full HD screens, the total canvas size may need to match the combined resolution of the video wall layout.

Step 3 - Create Scenes and Sources in OBS

Next, create your scenes and sources in OBS Studio.

In this demo, we use a Browser Source to display web-based content.

OBS can also capture and display other source types, including:

• Desktop screens
• Application windows
• Browser pages
• Dashboards
• Camera feeds
• Videos
• Images
• Presentations
• Technical software, such as DWG viewers or engineering applications

Prepare the scene layout in OBS according to the content you want to show on the video wall.

Step 4 - Project the OBS Canvas to the Video Wall

To show the OBS canvas on the MAWi video wall:

1. Right-click the OBS canvas.
2. Select Open Preview Projector.
3. Choose your video wall display.

Once selected, the OBS output will appear across the MAWi video wall.

Step 5 - Enable OBS WebSocket

Next, enable remote control in OBS.

In OBS Studio, go to:

Tools > WebSocket Server Settings

Make sure the WebSocket server is enabled.

The default port is usually:

4455

For security, enable authentication and set a password.

You will use this password later when connecting from the OBS Remote web app.

Click Apply and close the window.

OBS is now ready to receive commands from OBS Remote.

Step 6 - Connect from the OBS Remote Web App

Open the OBS Remote web app from any browser on the same network.

Enter the OBS computer’s connection details:

• OBS computer IP address
• WebSocket port, usually 4455
• WebSocket password

Click Connect.

Once connected, you can control OBS Studio directly from your browser on any PC connected to the same network.

Step 7 - Control the MAWi Video Wall

After OBS Remote is connected, you can control what appears on the MAWi video wall in real time.

From the OBS Remote interface, you can:

• Switch between OBS scenes
• Show or hide sources
• Control prepared visual layouts
• Manage what appears on the video wall without accessing the main OBS computer

This is ideal for control rooms, NOCs, SOCs, and command centers where operators need fast and flexible control over the video wall.

Common Use Cases

This workflow is helpful for:

• Control rooms
• Network Operations Centers, NOCs
• Security Operations Centers, SOCs
• Command centers
• Monitoring rooms
• Emergency operation centers
• Showrooms
• Demo rooms
• Technical presentation environments
• Live operational dashboards
  

Troubleshooting

OBS Remote cannot connect to OBS

Check the following:

• The OBS computer and the browser device are on the same network
• The OBS WebSocket server is enabled
• The correct IP address is being used
• The port is correct, usually 4455
• The firewall allows communication to OBS
• The WebSocket password is correct

The video wall does not show the OBS output

Check the following:

• The video wall layout is correctly configured in MAWi
• The MAWi Players are assigned to the correct screen positions
• Windows detects the MAWi Players as extended monitors
• The correct video wall display was selected under Open Preview Projector
• The OBS canvas resolution matches the intended video wall layout

The content does not fit correctly on the video wall

Check the OBS video output resolution and confirm it matches the video wall layout.

Also confirm that the screens are arranged correctly in the MAWi Display Config Tool and in Windows display settings.

Summary

By combining MAWi, OBS Studio, and the OBS Remote web app, you can create a flexible video wall control workflow.

MAWi manages the video wall layout and screen distribution.

OBS Studio manages the live visual content.

OBS Remote gives operators browser-based control from any PC on the same local network.

This allows teams in control rooms, NOCs, SOCs, and command centers to control video wall content quickly, easily, and in real time.
