Walls: screens that play together

Two kinds: In step, where each screen keeps its own content and they all change at the same moment (three menu boards side by side), and One picture across TVs, where one playlist is spread over a grid of up to 4 × 4 TVs.

1. In Screens, press Walls.
2. Under New wall, type a name and choose the kind. For one picture across TVs, also choose its Rows and Columns.
3. Press Make it.

4. On the wall’s card, tick its screens (click a location to open it).
5. Press Save screens. They join within seconds.
6. Give each screen a playlist of the same total length. They change together only when their loops are the same length; the card lists each loop and warns when they differ.
7. Start again from the top sends every screen back to its first item together.

   

One picture across TVs

4. Under Plays, choose the playlist.
5. For each place in the grid (Row 1, column 1 and so on), choose the screen that hangs there as you face the wall, then press Save places.
6. Measure from the edge of one TV’s picture to the edge of the next one’s, type it under Frames between pictures (mm) and press Save gap. That much is left out, so lines crossing a join stay straight. It uses each screen’s TV size, so set that on its page.

Every photo, video and sign is spread over the whole wall. Made in the wall’s shape (32:9 for two TVs side by side) it fills the wall; anything else is centred with black at the sides, or cropped if a photo or video is set to Fill. Every TV in it hangs the same way: all landscape, or all turned the same way (three portrait TVs side by side make a 27:16 wall).

The screens keep in step by Dislab’s clock, even when the internet is down. A screen is in one wall at a time; adding it to another moves it. Delete a wall and its screens go back to playing their own content.
