so you want a dual-dual-monitor setup with a KVM. Have you considered getting a single large 4k monitor/tv instead of 2 smaller ones(assuming the smaller ones are 1080p)? That would simplify a lot of what you would need to buy. I am running a 4k TV across 2 machines, physically it is 43" and I have the usable resolution/space of 4 22" 1080P monitors. The color on my TV is decent and it is a cheap 4k tv ($220 + tax), so may not be much more expensive that the hardware needed to implement the above. I use the TV input/remote switch + a USB keyboard-mouse switch to switch control from one to the other. On one of the machines I have a second small monitor(not on a switch) off to the side showing stuff I always want to be displayed(outside cameras).
