I got a cheap and compact KVM that connects via ethernet HDMI and USB
- HDMI to SBC: this is the video out
- USB to SBC: this is power from SBC and keyboard and mouse to SBC
- Ethernet: to host. This has the webserver where the KVM can be accessed with remote screen and other functionalities
A fancier version has the screen with the IP address
In this version I look at my router and get the DHCP assigned address
Just punch in the IP in the address bar and everything works out of the box
