You can switch video inputs using dcc (eg https://www.ddcutil.com/) so you could bind a hotkey to do that or if Synergy/Barrier/Input-leap can be scripted it could do that part too.
There is also a utility that watches for usb device change events on a cheap USB keyboard/mouse (no video) switcher that does the video automatically, but I had it lock up the usb stack on my Linux machine and never really got it to work reliably enough.
I use one of the cheap usb KM switches and changing the input on the monitor manually. Still kind of sucks, but better than nothing.
bumped into reading about ddc a couple times this month now. does this have support across wide number of monitors? i like high refresh rate monitors and want to switch between a macbook and windows pc quickly depending on home/work. seems like a lot of kvms are going to either choke, not have usbc inputs
Not an expert in this by any means, but I think all modern monitors have support for this (eg brightness controls, etc from an applet). Monitors are named, so it supports multiple monitors too.
