User Manual

Multiple Outputs

iOS and iPadOS devices currently only support one video output. However, if you need multiple video outputs with each in different video modes or settings, you can use multiple video outputs. This takes a single, high-resolution video output and outputs it in a grid to allow an external video processor to split it into different displays.

Layout

This section lets you choose the type of video output to create.

  • 2 x 2 works best with 4K video output, dividing it into four, 1920x1080 HD videos outputs.
  • 3 x 3 works best with 6K video output, dividing it into nine, 1920x1080 HD video outputs.

Screens

This section lets you configure each output by selecting from Screen 1-4 or Screen 1-9 depending on the layout. By default, Screen 1 is set to Lyrics Projection and the rest are turned off. When turned off, screens output the screen number.

Video Wall Processor Required

Using multiple video outputs requires an additional hardware product to physically split the signal into four separate HDMI outputs. Choosing this will open a web browsers to display a purchase option for the selected layout.
