Does anyone know how I would find a graphics card or set of graphics cards for Ubuntu which supported 5 monitors well, one being 4k?

I also don't want NVidia proprietary drivers due to bugs. They confuse something with monitors versus screens which breaks a lot of things. Nouveau works fine. Haven't tried AMD but I assume it's fine too.

AMD used to have special "Eyefinity" series cards which supported up to 6 displays (as in a single card / GPU would have up to 6 display controllers).

Though I don't know if that's still a thing, or whether they were well supported on linux, or how well they deal / dealt displays of different resolution. Also I'm pretty sure it only worked over native DisplayPort, so you'd need active adapters to plug in non-DP displays.

You might be better off taking advantage of Display Port Multistream. Some monitors have input and output display ports so they can be daisy chained. You can also get display port hubs. You can run one 4K display with a single display port or four 1080p displays with a single display port.

I'm not sure how easy it is in Linux to run different monitors at different DPI, so I'd keep that in mind.
