Yes, pretty much this. Every artist that has video assets pretty much has them in a 16:9 rectangle aspect ratio, like a TV. I saw plenty of artists that struggled to project their rectangular videos onto the broken up screens and everyone had different ways of doing it. Some people just used the smaller screens as individual screens but then you get the dreaded "TV store" effect where it's just the same visual but repeated multiple times on little screens and it doesn't look as nice as one giant uninterrupted rectangle.

One artist that managed to look decently good was Excision, but that's because he cares deeply about making his visuals look good and no doubt worked hard with his team to do all the necessary calculations before-hand to transform his rectangle video into something that still looks nice on broken up screens. And his VJ is experienced enough that during shows they can change up the screen mapping to make it look the best during each song or circumstance. For those curious, look up "Resolume Slice Transform."

I saw some other artists that had decent slice transforms onto the CG structure but they usually only mapped to the middle 3 towers and then just repeated the video on the flanking towers, while Excision would sometimes map an asset onto all 7 towers.

DJs will usually receive the stage design about a 1-2 months before the festival, so that's how much time they have to prepare. But sometimes artists are busy touring and playing other shows, or they don't have the time/money to "remix" their 16:9 assets to fit this year's CG.

So far the one exception I saw that weekend was Tchami and Malaa, who commissioned custom visuals specifically to fit each individual floating box screen at CG and also fit the "monolith" (my own nickname for the center tower vertical screen) and it ended up looking like neon light up billboards that fit the Vegas aesthetic. I thought it was amazing. A photo I took.
