I use Resolume professionally in my job building and operating LED walls for live events. I have a rackmount custom PC with a 4090 in a shockproof road case with popout monitors. One important skill is being able to map content onto multiple video walls. For example at a volleyball charity event I had a jumbotron with 4 walls where I needed to put camera shots and sponsors and also 2 walls on the side for a live charity donation and tournament schedules. I use resolume to route all the video signals. It's actually 1 4k screen sliced into 6 screens.
