It isn’t clear to me if all the ports on the KVM need to be populated. Do you need to use a type c to DP cable, or can you just use a single type C cable for power + dp + data between the KVM and laptop?
I tried looking at those, but it was unclear to me whether you had to use additional cables, or if the type C PD was enough to cover everything for a laptop with one cable.
If not, is the only one-cable solution to go into a dock, and then go from the dock to the KVM?
So, the KVMs connections are tied together in rows. If you plug the laptop into the bottom USBC port, it does not have a connection to the top DisplayPort port. With just a USBC on the bottom you will get PD, data, and display to 1 monitor. The DP to USBC is required above it to get your 2nd monitor connected. I hope that made sense, let me know I can go further into it or make a video showing it in action
