For effect, video walls can be any shape or arrangement, to be more eye-catching and interesting, and carrying a single disaggregated image, or multiple but co-ordinated images. Graphics card drivers are good at grouping rectangular arrays, and rectangular media is efficient. For everything else, there are options.
Let’s take an irregular array of 8 panels that needs to be able to show a contiguous image. Except for the extreme-right panel, we would not be wasting much of a rectangular media frame:
Delta software offers composition mode, whereby elements of the source media are placed individually into display areas. This allows for very efficient media delivery by compacting just the visible areas during the graphic design, into a rectangular frame that minimises unused pixels.
In this case, the solution could be to take the displayed areas only, and compact them into a rectangular frame, a saving of 60 per cent:
Delta will take each element, rotate where required, and place them in the total canvas area:
There are many solutions, and a simple alternative in this case may be simply to extract the outlying area as a separate media resource and cut the right-hand quarter off the original.
Display controllers (see below, the Datapath Fx4, for example) can also produce a similar result, placing parts of a rectangular image into the distributed video space. The visual result is exactly the same.
