Can someone explain to me how to connect so many monitors? Like I had two HDMI ports and I think thats pretty normal? How are people doing 3+ monitors?
USB video dongles.
You can daisy chain displayport, as long as you have the bandwidth for it. I think the real issue is not how many monitors, but just how many pixels you're trying to drive. Since secondary monitors are typically 1080p, the whole collection of them should be the same as a 4k main monitor.
You need a graphics card or smth to even have the ability to have >3 displays. Some Macbooks have a 2 screen limit, so if you want to use only external monitors you have to close the lid. PC graphics generally allow at least 3 screens. But thunderbolt usb is an option.
I have a tower pc with graphics card, dual booting windows and linux so in theory I can put 3 on here? Interesting
Linus Tech Tips did a video on having windows alongside macOS on the smae machine. They did it by having both as VMs on a barebones linux machines. Theoretically you could then dedicate each one of the operating systems to an OS, and run linux, windows, and mac side by side. My guess kn feasibility: very hard.

My laptop and a thunderbolt dock can do 4, a 4k panel, 2 qhd and a 1080p all at 30fps
Every Screen adds on bandwidth needs, the more pixes and faster refresh, the fewer screens you can handle.
You can get there with multiple gpus, or if you have lower demands, usb->html
Good grapics cards have 3, you're not limited to one graphics card
