I wondered that too, maybe he is routing everything through usb-c and uses a usb-c hub? Conventional KVMs have VGA, I doubt he uses it. Maybe he has an HDMI one. I've got a 4k display and finding a KVM that supports 4k 60hz is nearly impossible where I live. I plan on using a regular KVM to share mouse and keyboard via USB and use my monitors second input for manually switching between PCs. It's a two step solution but at least doesn't break the bank. 4k has been a source of lot of frustration for me. Regular adapters don't work, regular cables don't work, you can't find content. HiDpi scaling is not that great. I feel like an early adopter. Everything is a hassle, parts are expensive. I had a 1080p 32 inch monitor once, it was great but the resolution was lacking. I replaced it with a 32 inch 4K one, but I couldn't get the same experience.
