I'm been daydreaming about a setup involving 5-8 screens/frames fixed to a wall. When I pressed a button on a remote, they would all shift to whatever is on that 'channel', (i.e. all showing images of different sunsets when I press the 'sunset' button), which could be an image or a loop of images. Ideally, I'd be able to adjust what's on which 'channel' for each screen without having to take them down off the wall!
Is this currently possible? And how can I learn more about setting it up?
I don't mind having a dedicated minicomputer for all this, and I'm fairly tech-literate, but I really know nothing about this field. It seems as though this should be a fairly common use case, but I haven't really been able to find the right terms to google!
