KVM is working as expected at the moment. Video cable adapters will not work, so use good quality cables with proper connectors. The DP to HDMI adapters I had didn't work. The listing mentions they won't, but I had to check. I use DP-Mini DP cables from Surface Pro dock, DP-Mini-DP cables from KVM to monitors and DP-DP cables for my desktop which is equipped with Nvidia 1080 GPU.
