A video wall combines several displays into one large picture, such as two TVs side by side in a shop window or four in a square. You create it under Video walls, assign content to the whole wall at once, and can dissolve it again at any time.

How a video wall works

On its own, each display shows the whole scene. On a video wall, the scene is spread across the whole surface, and each display shows its part. The surface is a grid of up to 4 × 4 tiles, and each tile counts as 1920 × 1080 pixels. The displays don't need to be connected to the same device.

A scene is fitted into the shared surface of a video wall. The left display shows the left half, the right display the right half, and a display without a video wall shows the whole scene.

Keep three things in mind before you build:

  • All displays switch content at the same time, but videos are not frame-synchronized across the seam. Video walls work best with scenes, images, and calm transitions.
  • Videos on a video wall play in the browser, which needs more power. Avoid very large videos on big grids.
  • Every device needs a correct clock. Clock out of sync on one display affects the whole wall.

Steps

Create the video wall

  1. Open Video walls. If it says The video wall is not enabled yet, click Enable video wall. If the booking is missing, the dialog offers to book it.
  2. Click Create video wall and enter a name.
  3. Set Columns and Rows, then click each tile and choose the display that hangs there. Tiles may stay empty.
  4. Click Create. The portal confirms Video wall created.

The Create video wall dialog with a 2 × 1 grid: the Name field with the placeholder Shop-window band (1), the Columns and Rows fields (2), the tile grid with the tiles still free (3), the Makes a surface of … pixels line (4), and the Create button (5)

You can also select several displays under Displays and choose Combine into a video wall.

Assign content

  1. Open the video wall. The card What runs on this surface replaces the assignment of the single displays.
  2. Click Assign program and choose a program, scene, playlist, or file. It runs on all displays of the wall.
  3. If the displays still show different things, click Apply to the whole surface.

For very wide walls, design scenes in the Wide format, which the template gallery offers for aspect ratios from about 21:9.

Dissolve the video wall

Open the video wall, click Dissolve video wall, and confirm with Dissolve. The displays keep their seats and their last content, and each one shows the whole scene again.

Check the result

The video wall's page shows how the displays sit next to each other, and below it Displays of this video wall with each display's status and picture. All displays are showing means everything is fine. Otherwise, the line names the display that needs attention.
