What I am looking for is actually something much simpler. I have a laptop and a desktop. I want to click a button to switch between them for the same set of monitors and USB-connected devices.

The USB-connected devices is ok since I can use a USB switcher. But I can't figure out how to switch my monitors' input sources without manually using their OSD and control buttons.

Maybe try my Lunar app (https://lunar.fyi/) if you’re on macOS. It can switch inputs using DDC if the monitor implements the VCP code for it, and it can assign a hotkey and a specific brightness/contrast for the input if needed: https://lunar.fyi/static/img/input-key/768_input-key.webp

For Linux, there’s ddcutil that can do that, and for Windows there’s TwinkleTray.

I’ve had good luck with this CableMatters USB KVM switch. It switches the USB devices along with a DisplayPort. So I leave the monitor’s input alone, and run its DisplayPort to this, and then DP cables out to my Mac and PC (well, DP-to-USBC for the Mac)
