After having created a media feed, we now want to map the media feed onto the panels, so select one of the panels, and go to the Parameters section in the Side Bar.
Click on the feed drop-down button to show a list of available feeds, and select the one you want. Do so for the other three panels as well, and you will see the video playing on all 4 screens.
To get the 4 screens working as 1 screen however, we have to set the mapping for each panel, so select one of the panels, go to the Parameters section, and unfold the 'Mapping' area (by clicking on the small button in front).
There you see the media area, subdivided in H x V sectors (as earlier defined for the feed). This will allow for easy selection of which sector of the media you want on the selected panel. You can just click on one of the sectors (or click and drag to select multiple sectors). (You can always set the area with the 'Left', 'Top', Right' and 'Bottom' entries as well.)
Do so for all 4 of the panels, and you will get the panels to work as one large screen:
You can mix and use multiple media feeds and sources, for example using another feed called 'Camera',
which is attached to a another source, to show on one of the panels:
