About Video Walls

If you want to stretch your content across multiple physical displays next to each other, you have to use a video wall setup.

To set up a video wall, you must send an advanced configuration to your device through Wallboard. This configuration defines the layout, position, orientation and resolution of each display in the video wall.

Note

With a Premium license you can use up to 2 displays at once in a video wall, however for more than 2 displays a Video Wall license is required!

Understanding the key parameters in the configuration

Each video wall setup requires specific parameters in the advanced configuration in order for it to work.

• type: Always set to SCREEN_CONFIGURATION for video wall setups.
• outputName: The HDMI port for each screen, e.g. HDMI-1, HDMI-2, etc...
• screenX/screenY: The top left starting coordinates of the individual screens where X is the width and Y is the height.
• transform: Sets the rotation for each screen. Options include:
  • normal - default, no rotation
  • 90 - 90 degrees clockwise
  • 180 - 180 degrees
  • 270 - 90 degrees counterclockwise
• videoMode: Specifies the screen resolution and refresh rate, e.g. 1920x1080x60p.
