So my PiKVM has issues and gets no video from my Proxmox host
I bought a JetKVM and it works flawlessly and was so easy to setup
I'll debug the PiKVM at somepoint (it's also via a HDMI & USB KVM switch as it's a DIY setup with their instructions but it allows control of 4 systems (when working)
For now, JetKVM it is as I only need it for 1 machine
